Instrument integration

Can I calibrate the speed through water (STW) in Tactiqs?

Yes. Tactiqs supports speed calibration, you can apply a correction factor to the raw STW data received via NMEA to account for uncalibrated speed sensors.

Does Tactiqs work with the ORCA wireless system?

No. The ORCA system uses a proprietary protocol over Wi-Fi that only works with the ORCA app. They do not allow third-party apps to use the ORCA data stream. If you have an NMEA 2000 network, the recommended solution is to use a standard NMEA-to-Wi-Fi gateway such as the Yacht Devices YDWG-02, which provides standard NMEA-183-over-Wi-Fi that Tactiqs can read.

Is the B&G H5000 processor required to use Tactiqs?

No, the H5000 is not required. Any NMEA-to-Wi-Fi gateway that outputs standard NMEA 183 over Wi-Fi (such as the Yacht Devices gateway) will work. The H5000 is mentioned frequently because it is the most common system among Tactiqs users, and Tactiqs has deeper integration with it for sending data back to B&G displays and configuring wind calibration tables.

How do I send Tactiqs calculated data back to my boat instruments and displays?

In iOS Settings > Tactiqs > Advanced, enable 'Tactiqs data over NMEA.' Set the NMEA transmit address and port to match your WiFi gateway's listening address and port. Configure the metric-to-channel mapping on tactiqs.io under your boat's display settings, then sync your device. Tactiqs sends data as standard NMEA-183 XDR transducer sentences, ensure your WiFi gateway is connected to both NMEA-0183 input and output ports on your processor. For B&G H5000 systems, data can be sent via the WebSocket interface (User channels 0-9), which allows sending the race timer, performance metrics, and custom values to H5000 displays. For Garmin GNX displays, data can be sent via the Yacht Devices NMEA-2000 YDWG-02 gateway with control over field names and units. Please note that the YD gateway is the only model that supports sending the Garmin GNX sentences, other manufacturers do not support sending arbitrary NMEA2000 PGNs.

What should I check if Tactiqs cannot connect to my NMEA gateway?

Common troubleshooting steps: (1) Verify your iOS device is connected to the correct WiFi network (the one your NMEA gateway broadcasts or is connected to). (2) Check the IP address and port in Tactiqs settings match your gateway's configuration. (3) If your device shows a 169.254.x.x IP address (standard placeholder for an unassigned address), it has not received a proper address from the router -- try reconnecting to WiFi or restarting the router. (4) Try loading the gateway's IP address in Safari to verify network connectivity. (5) On sme gateways, ensure only one app is connected to the TCP port at a time if using TCP. (6) WiFi connection drops during races can be caused by interference, weak signal, or the iOS device trying to switch to a stronger network -- disable auto-join on other networks and keep the device close to the WiFi source. (7) Disable any VPN connections, which can interfere with local network communication.

Should I use TCP or UDP for the NMEA network connection?

Both work on a small boat network. TCP is recommended when available, as it provides a reliable connection. Some simpler NMEA gateway devices only support UDP, which broadcasts data to multiple clients. On a single-access-point WiFi network typical on a boat, the latency difference is negligible. UDP can be slightly faster on complex networks but may have some packet loss. If TCP connections to WiFi gateways drop and do not re-establish, try UDP on port 10110 (the standard NMEA port) as an alternative.

Can Tactiqs integrate with an older B&G WTP2 system?

Direct integration with the WTP2's proprietary data protocol is not possible, as B&G discontinued that interface after the H3000. The recommended approach is to use an NMEA 183 to Wi-Fi gateway such as the Yacht Devices gateway, which is bi-directional. You can set up one channel to receive data from the WTP2 and another to send data to the processor's NMEA input. On older systems, the FFD displays can also ingest select NMEA 0183 sentences. Note that only NMEA-enabled Fastnet FFDs with software version 9 or higher support XDR inputs. You can tell if your FFDs have NMEA support by checking for the additional brown and violet leads in the display's connection cable.

How do I connect Tactiqs to a B&G Vulcan or Zeus chartplotter via WiFi?

The Zeus and Vulcan plotters can output NMEA 0183 data over their WiFi or Ethernet connections. In the Zeus NMEA menu, go to NMEA over Ethernet settings and enable forwarding for at minimum: RMC (GPS position), DBT (depth), HDM (heading), MWV (wind), and VHW (water speed). Connect your iOS device to the same WiFi network. In Tactiqs, set the data source to TCP and enter the plotter's IP address and port. Note: the Zeus/Vulcan WiFi does not support receiving data back from Tactiqs -- for bidirectional communication, use a separate NMEA-to-WiFi gateway like the Yacht Devices YDWG-02.

Can I exchange routes or polars between Tactiqs and a B&G H5000/Zeus chartplotter?

Route and waypoint exchanges with B&G Zeus plotters are not supported by B&G. Polars are also not exchanged with the H5000, as Tactiqs uses its own internal performance data which users can fine-tune based on measured polars. Tactiqs does, however, push TWS/TWA calibration data back to the H5000 to ensure wind data is displayed consistently on B&G deck displays and in the app.

Is COG (Course Over Ground) available in magnetic, or only as true?

COG is always defined as true track over ground. If you use COG as the heading source, Tactiqs applies the magnetic variance to calculate your HDM (Heading Magnetic) metric.

How do I change the NMEA TCP server address and port in Tactiqs?

Go to the Setup tab (left edge swipe) and click on the Setup Wizard in the bottom left to configure the data connection type, IP address, and port number. Alternatively, you can adjust these individually in iOS Settings > Apps > Tactiqs under the NMEA Data Source section. If your instrument data comes over the network, set the GPS source to 'Network.'

How do I connect Tactiqs to a Garmin GPSMAP instrument system?

Garmin devices have varying connectivity support. On some devices, you can connect to TCP port 39150 to receive NMEA-183 data, but most newer Garmin chartplotters only support their own proprietary Captain's app interface. If TCP port 39150 does not work, the recommended solution is to add a Yacht Devices Wi-Fi gateway directly on your NMEA-2000 network. It can create its own Wi-Fi network or connect to your Garmin Wi-Fi as a client, keeping everything on one SSID.

How do I connect a SailTimer wind vane to Tactiqs?

SailTimer uses a proprietary Bluetooth connection, so you need to run the SailTimer API app in the background as a bridge. Launch the SailTimer API app and connect it to your sensor -- you should see wind data in the text window. Then put it in the background and switch to Tactiqs. In the Tactiqs Settings under NMEA Data Source, select 'UDP + Internal Sensors' for instruments, 'iOS Internal' for GPS, and set the UDP Listening Port to 55554 (which is the port the SailTimer app transmits on).

How do I access and interpret the NMEA diagnostics screen?

The NMEA diagnostics screen shows incoming data in real time. Access it by long-pressing the Wifi/GPS status indicators. Blue crosses indicate valid received sentences; red crosses indicate sentences with errors or missing sentences. Use this screen to verify your gateway is sending the expected sentences and to identify data quality issues before racing. Here you can also set the neutral device position for the internal heel and pitch sensors, and with a swipe on the right edge you get access to the setup page for B&G H5000 processors (if connected to such a unit voa the B&G websocket protocol).

What NMEA heading sentences does Tactiqs support?

Tactiqs parses HDT, HDM, HDG, and THS (True Heading and Status) heading sentences. HDM is the generic magnetic heading sentence, while HDG is commonly associated with B&G Zeus systems. All Wi-Fi gateways for NMEA-2000 networks translate NMEA-2000 to NMEA-0183 sentences since there is no standard yet to transmit NMEA-2000 messages directly over Wi-Fi.

How do I enable and retrieve NMEA log files from Tactiqs?

Enable raw NMEA logging in iOS Settings > Tactiqs > Advanced Settings. Log files are stored in the app's Documents folder and included when you upload a race through the normal sync process. To retrieve files manually, connect your iPad/iPhone to a computer and use Finder (Mac) or iTunes (Windows) to access the Tactiqs app's Documents folder. NMEA logs are useful for troubleshooting data quality issues with the support team.

What instrument compatibility does Tactiqs require?

Tactiqs requires instrument data as an NMEA-183 stream over WiFi. Most current instrument makers (B&G, Garmin) include WiFi hotspot options in their chart plotters that support this. For systems with wired-only output, use a WiFi adapter such as those from Yacht Devices (NMEA-0183 WiFi Gateway for serial ports, or NMEA 2000 WiFi Router for N2K networks). The most important data inputs are position, boat speed, heading, wind angle, and wind speed. A fixed GPS puck antenna provides better accuracy than the built-in iOS GPS. Heel and pitch data can come from the iOS device's internal sensors if mounted on the boat. The Support page has a guide for selecting your connection options.

How do I set up a WiFi gateway (YDWG-02, DMK, or similar) with Tactiqs?

Connect the gateway to your NMEA network. Configure the gateway's WiFi settings and NMEA routing (route the input port to the TCP/UDP server output). In Tactiqs, set the data source to match the gateway's protocol (TCP or UDP) and enter the gateway's IP address and port. The Yacht Devices YDWG-02 is the recommended gateway. For sending data back from Tactiqs to instruments (e.g., Garmin GNX displays), ensure the gateway is connected to both NMEA input and output ports on your processor. For NKE instrument systems, you can use the NKE Wifi Box to access the NMEA data.

What do I need to connect Tactiqs to my boat's NMEA-2000 instrument network?

Since iPads and iPhones lack wired connections, you need an NMEA-to-WiFi gateway. There is no standard for transmitting NMEA 2000 data directly over WiFi -- gateways translate NMEA 2000 payloads into NMEA 0183 sentences for WiFi transmission. Recommended gateways include the Yacht Devices YDWG-02 or similar devices that output standard NMEA-183-over-WiFi. If you are purchasing a gateway to integrate Tactiqs we recommend the Yacht Devices models.

How do I connect Tactiqs to a B&G H5000 system?

The H5000 processor has an Ethernet port that can be connected to a Wifi Access Point configured for a network with addressing in 192.168.0.0/255 and a DHCP pool from 192.168.0.10 - 192.168.0.200. In Tactiqs, enter the H5000 default settings for a B&G Websocket connection: IP Address 192.168.0.2, Port 2053. Via the Websocket interface Tactiqs can also send performance data, race timer sync, and wind calibration tables back to H5000. For accepting external data channels the H5000 needs to run the Hercules or Performance software packages.

How do I connect Tactiqs to a Raymarine or Tacktick wireless instrument system?

Raymarine systems need to output standard NMEA 0183 data over WiFi. Some Raymarine systems use proprietary interfaces. The recommended approach is to connect a Yacht Devices WiFi gateway to the NMEA port of your Raymarine T-122 NMEA interface. For Tacktick wireless instruments, the T-122 bridge converts the wireless data to NMEA 0183, which then feeds into the WiFi gateway.

Can Tactiqs send data to Sailmon, Raymarine Axiom, or other third-party displays?

Tactiqs can send data using standard NMEA-183 XDR transducer sentences, select NMEA-2000 PGNs, the Garmin GNX display PGNs, via B&G Websocket connections, and the Sailmon E4 UDP connection spec. Whether a particular display can read these depends on the display's support for these messages. Sailmon and Raymarine Axiom compatibility depends on the specific model. Contact the Tactiqs support team for specific compatibility information with your display model.

Can Tactiqs send data to Garmin GNX120/GNX130 deck displays?

Yes. Garmin is the only display manufacturer that fully supports third-party data sources. Tactiqs can drive all custom metrics to GNX displays, including field titles, values, and which page layout is active (e.g., a pre-start versus race layout). You can send up to 10 metrics. The GNX120 and GNX130 run the same firmware and differ only in size; the GNX120 can display 3 metrics per unit. You need a Yacht Devices YDWG-02 gateway to transmit data from Tactiqs to the Garmin displays. On the YD setup page, configure an additional server with UDP, RAW data protocol, port 10111, and Direction: Receive Only. In Tactiqs, use the YD's IP address and port 10111 for NMEA Tx. The GNX displays have excellent readability in bright sunlight thanks to their transflective panels.

How should I handle multiple GPS sources and GPS-related issues?

Having multiple GPS sources can cause conflicts. Ensure only one reliable GPS source is configured on your NMEA network. Use the NMEA Receive Settings in Advanced Settings to select which GPS sentences to accept. GPS data is primarily received via the RMC sentence containing position, time, and date. If RMC has empty or malformed timestamps, data processing will fail. If GPS sentences use a non-standard talker ID (the first two letters after '$'), add it in iOS Settings > Tactiqs > Advanced > NMEA Receive Settings.

Can I use a VPN while connecting to my NMEA gateway with Tactiqs?

Using a VPN while connected to your NMEA gateway is not recommended. Depending on your wireless carrier settings we have seen the app not being able to talke to a local gateway, or multiple devices running Tactiqs not seeing each other.

Can Tactiqs send performance data back to B&G H3000 and H2000 displays?

Yes. Tactiqs supports sending the following B&G proprietary NMEA-183 sentences back to a B&G H3000 processor: $PBGTTBS (Polar Speed in knots, Polar performance %), $PBGTLAY (Distance to Layline in Nm, Time to Layline in hhmmss), and $PBGTSTR (Distance to Start Line in metres, Time to Start Line in hhmmss). For H2000 systems the FFD display may accept NMEA data if it is the NMEA version (noticeable via the purple NMEA-input lead in the display's harness). H2000 B&G FFDs with NMEA capability need to be at least firmware version 9 to accept inputs.

How do I connect Tactiqs to Expedition navigation software?

Tactiqs can read the Expedition protocol. In Expedition set up a network that re-broadcasts its data, then use Expedition as the data source data in Tactiqs with the same UDP port.

How does the speed dampening setting work?

The speed dampening function (iOS Settings > Tactiqs > Advanced) smoothes speed readings. Units are in samples (one sample = one receive interval, e.g., 1 second for B&G H2000). Valid range is 0 to 100, designed primarily for high-rate speed sensors.

Can I connect Tactiqs to a Raspberry Pi running as an NMEA WiFi gateway?

Yes. Enter your Pi's IP address and port into the app settings. If running kplex, TCP should work fine. For NMEA data to show up, Tactiqs needs to receive GPS RMC or GGL messages, as those trigger the update interval.

How do I configure a Digital Yacht WLN10 WiFi gateway with Tactiqs?

Set the instrument source in Tactiqs settings to UDP only, and set the port number to match the WLN10's configured port. If the WLN10 uses a non-standard talker ID, add it under Advanced Settings > Custom NMEA Talker ID. Note that the WLN10 only supports one device connection at a time; power-cycling may help if it stops sending data.

Does Tactiqs support the SignalK protocol?

No. Tactiqs does not support SignalK, as it is not a marine standard. The app requires NMEA-0183, B&G Websocket, or Expedition Protocol data.You can verify incoming data in the network diagnostics view: the gray area at the bottom shows raw incoming data.

Can I use a Calypso Ultrasonic wind sensor with Tactiqs?

Yes, the Calypso Ultrasonic wind sensor is fully integrated with Tactiqs. It connects via Bluetooth automatically (no manual pairing needed, similar to heart rate sensors). Keep your NMEA Data and GPS sources set to Internal in the Tactiqs settings, and enable the Calypso sensor option. The app will automatically connect when the sensor is in range and remembers the hardware ID of your specific unit, so it will not read data from another boat's Calypso. Mount the sensor with its front notch aligned with your bow. If you notice different AWA values on port and starboard tacks with the same trim, adjust the centerline AWA offset in the Calypso section of the Tactiqs settings. The Calypso also has a built-in compass, useful when the phone cannot be mounted perpendicular to the centerline. The larger model with a solar panel is recommended so you do not have to charge it. It is a great option for smaller boats without wired instruments, as it requires no wiring and can be mounted on a small pole. You can use the Calypso with the basic subscription.

How do I connect Tactiqs to an NKE instrument system?

Tactiqs supports NKE systems via the NKE Wi-Fi gateway (Box USB Datalog WiFi). Configure the gateway to send NMEA data over Wi-Fi via UDP on port 10110. In the Tactiqs app, use the Setup Wizard (found in the SETUP tab via left-edge swipe, bottom left) to select UDP transport and the matching port number.

Weather routing

How does the weather routing engine work in Tactiqs?

Tactiqs includes a weather routing engine that uses GRIB forecast data and your VPP polars to calculate optimal routes. It builds a half-circle search pattern from start to finish in iterative steps, identifying the fastest angle towards the next waypoint or the finish for each step. The engine requires forecast data and internet access to fetch weather -- it cannot run on current wind conditions alone. Routes can be calculated into the future as long as GRIB data is available for the time window up to a maximum of 10 days. If the router fails, common causes include: start/end positions too close to shore, marks too closely spaced for the resolution, or no internet access. Weather routing is best suited for courses where waypoints are at least several nautical miles apart in fairly open water. For inshore courses or in very constrained waters where the router cannot find a path, you can instead set the course, tap the weather icon, and adjust the race start time to use forecast data for condition calculations without full routing. Weather routing requires internet before racing but no connectivity during the race itself.

Does Tactiqs integrate with PredictWind for weather data?

No. Unfortunately PredictWind does not provide a data API to third-party applications because they offer their own online routing service.

Can the routing and weather functions be used from a client device?

The routing module can only be operated from the master device which holds the downloaded forecast data and must be an iPad. However, once a route is created and activated on the master, client devices display the same route, position, and leg TWA information. The only reason to go back to the master iPad is to trigger a route refresh with new weather data (common in longer offshore races over 24 hours).

Charts and navigation

How do I use Navionics charts in Tactiqs?

Tactiqs supports Navionics charts in the Navigate tab. To use them: purchase a Navionics subscription (via the Navionics Boating app), then enable the chart layer in the app settings. Charts can be cached for offline use by panning and zooming over the area you need while connected to the internet. You can adjust the depth detail shown on the chart and the depth unit in the app settings.

Why are some marks on the chart showing as numbered waypoints instead of their proper names?

Marks that display with their correct name are marks stored in the Tactiqs database. If you are using Navionics charts, you will see the original marks within the chart, and any marks defined in the Tactiqs database. If you tap on a Navionics mark to add it to a race course, the course will add a numbered waypoint at that same location. Numbered waypoints are not in the Tactiqs database and specific to your device - they are intended to tweak or define a one-off course setup, or direct a routing solution a specific way. For marks that you plan to use repeatedly, it is best to creat an entry on tactiqs.io under Marks in the database.

Where can I see the remaining time to the next mark during a race?

To see the remaining time to the next mark, select the 'Time to next mark' metric on any numerical field in the Race views or in the Navigation side/bottom area. If you are not reaching to the next mark, you can also choose 'Layline Time,' which gives you the time to the next mark's tacking or gybing layline. The annotation displayed along a leg in the Navigate view always shows the full estimated time for that leg given current conditions.

Which start data is most useful inside 20 seconds to the start?

It depends on your typical starting techniques and how the rest of your fleet behaves. Auto time/distance to line is more useful when you have aggressive starters in the fleet and need to react to last-minute luffs and quick course changes. Time to burn is better suited for more conventional timed run starts. Choose based on the style of starts common in your racing.

How do I get a bearing and distance to a specific point on the chart?

Long-press on the chart at any point to get the latitude/longitude of that location along with the bearing and distance from your current position. These values will continue to update as your position changes.

Can Tactiqs handle long races or multi-day races?

There is no theoretical limit to recording duration. The app continuously writes to a SQL database containing the race log data. If you restart the app during a race, it recognizes the ongoing race and continues adding records.

VPP/polar data management

How do I calibrate my wind instruments using Tactiqs?

The full wind calibration table feature with detailed TWA calibration is available on the iPad version of Tactiqs. On iPad, you can adjust the wind calibration table to correct for systematic errors in your wind instruments across different wind angles. The User manual provides a detailed step-by-step instruction on how to annotate tacks and gybes to generate the correction profiles. The resulting TWA and TWS corrections are stored on the same device and applied to subsequent races. If you are connected via a B&G H5000, the calibration tables are sent to the processor to ensure consistency between the wind data shown in your on-deck displays and in the app.

How do I set up, manage, and train VPP polar data in Tactiqs?

When creating your boat on tactiqs.io, select your boat type from the VPP database to load baseline polars from our collection of VPPs. If your type is not listed, contact us as often we can find a source to get you started. You can fine-tune polars under My Boats > VPP editor (target symbol). ORC certificate data can be imported via the ORC reference number for your boat found on the bottom left of your certificate. To import other polar formats, contact us as we can likely import the data for you. Tactiqs collects dynamic VPP data during sailing by identifying steady-state 15-second intervals where speed, heading, and wind angle are stable. Only data from actively running sessions (between Start and Finish) is collected, and only uploaded logs contribute to your aggregate polars. The Analyzer's Sail Stats section includes a slider to adjust outlier filtering, the default settings work well for most typical cruiser/racer designs. For boats where no VPP data is available (e.g. for dinghies where crew weight is a key factor), you can learn VPPs in dedicated up- and downwind runs. The is described in step-by-step instructions in the user manual.

What does Speed Performance percentage mean, and how are VMG and VMC calculated?

Speed Performance percentage shows how your actual boat speed compares to the VPP target speed for the current wind angle and speed. VMG (Velocity Made Good) is calculated against the wind direction, representing effective speed toward or away from the wind. VMC (Velocity Made to Course) is calculated against the course direction to the next mark, showing effective speed toward the mark. VMG performance is based on your VPP polars and instrument data (boat speed and wind angle).

If I adjust my polars after a race, does that change the performance data for prior races?

No, the polar target speeds are recorded as part of the race log, so if you change the polars after a race, it will not affect the performance data of that previously recorded race.

How can I disable specific NMEA sentences in Tactiqs if they contain bad data?

In the iOS Settings app, go to Tactiqs and then Advanced. There you can disable specific NMEA sentences. This is useful when some sentences from your instruments contain bad data (e.g., incorrect timestamps or positions). For example, if RMC messages from your system have timing issues, you can disable RMC and Tactiqs will fall back to using GLL sentences for position and timing instead.

What parameters does Tactiqs use to analyze tack and gybe maneuvers?

Tactiqs analyzes maneuvers using several correlated parameters: heading change, ingoing TWA and outgoing TWA, and boat speed are the key inputs. The time loss indicator is based on comparing the progress to the next mark based on the actual progress versus the theoretical progress if you had continued the same tack/gybe. Tactiqs also tracks bear-aways and turn-ups in addition to tacks and gybes.

How do I access the side menus on an iPad Pro?

The swipe needs to be a quick movement from the edge of the screen edge towards the inside. If your iPad case prevents from performing the gesture, you can enable Hot Corners in iOS Settings > Tactiqs. This allows you to tap in the bottom-left and bottom-right corners of the screen instead of swiping. Yellow indicators appear in the corners when this feature is enabled.

How do I create a boat profile and set up VPP data?

Go to tactiqs.io and sign in. Click the Boats tab to create a new boat. Select your boat type from the VPP database, or contact support if not listed. Enter your hull number (a unique identifier, typically 10-15 digits from your registration -- letters and digits accepted). Set the GPS antenna offset from the bow, which Tactiqs uses to calculate distance from the starting line by determining where the bow is relative to the line. After creating the boat, open the app, go to SETUP, log in, and Sync to transfer your configuration.

Can I control which sailing data is included in my aggregate VPP polars?

Yes. Tactiqs only collects dynamic VPP measurements when a race or training session is actively running (between Start and Stop). Only the logs you choose to upload with VPP data are pulled into your aggregate VPPs, giving you full control over which data sets build your polars. You can exclude sessions with poor data or time spent under power.

How do I set up the Actisense W2K gateway to work with Tactiqs?

On the Actisense W2K gateway, select TCP server mode with NMEA-0183 output, then configure the Tactiqs app to point to the Actisense's IP address and port number. Note that the Actisense incorrectly advertises itself as a router connected to the Internet rather than a private WiFi network. If your iOS device has cellular data and you cannot connect to websites while on the boat's WiFi, this is the cause. Temporarily turning off WiFi on the iOS device will fix web connectivity when needed.

Can I use either a comma or a period as the decimal separator when entering VPP data?

You should use a period separator when entering VPP data on the tactiqs.io web portal.

Race analytics and performance metrics

Where is the race log data stored, and can I access it from a different device?

The race log used by the in-app Analyzer is only available on the device that acted as the master during that race and recorded the performance log. However, once uploaded to the Tactiqs cloud, you can access track metrics, sail heatmaps, dynamic VPPs, and detailed maneuver metrics through the My Races page on tactiqs.io from any browser. The system is designed with the backend as the main aggregation database.

How does SailCast race playback work in Tactiqs?

SailCast is a feature where participants upload their race data after finishing. The race can then be played back for review by the competitors or the sailing club or fleet at the after-race gathering. Sailcast provides a 3-dimensional replay of the race with ladder-lines and laylines overlaid on the course to see how different competitors performed relative to each other.

How do the wind speed bands work on the polar charts?

The polar chart displays VPP target speeds at different wind speeds as concentric curves. Each curve represents a specific wind speed band. Your dynamic VPP measurements (colored dots) are plotted against these theoretical curves to show actual versus expected performance at each wind speed. The colored wind speeds associated with each curve represent the center of each band.

Can I import race data from other sources such as GPX or NMEA log files?

No. Tactiqs captures a wide range of parameters required for its race analytics, so there is no option to upload previous track data from GPX or NMEA logs to the backend. Race data must be recorded live through the Tactiqs app.

What is the preferred method for uploading race data -- by sail or combined?

Uploading polars by sail is the preferred method, as it provides the most useful data for analysis. Make sure you have the sail usage intervals set in the Analyzer for each sail. In the chart view, swipe left across the Track Metric selection to access the sail selector, then tap on the track to mark each sail's usage interval (points it was set and doused).

How does the finish work in Tactiqs, and do I need to press the Finish button?

If you have a course set for the race, the app will finish the race when passing the last mark pr the finish line (if configured in the course definition. If you do not have an active course, you do need to press the Finish button to end the recording session and save the race log. The data between Start and Finish events constitutes your race log.

How does sail tracking work in Tactiqs?

Tactiqs tracks which sails are in use during each race for per-sail performance analysis based on sail-set and set-douse events. After you set up your sail inventory on tactiqs.io, you can select the active sails from the sail tracker. Set and take-down times are recorded for each sail. If you missed any set or douse events, you can also add these usage events in the Analyze view after the fact. After upload, tactiqs.io lets you slice performance data by individual sail across sessions. Reefing configurations, e.g. Main Full, Main Reef 1, Main Reef 2 should be set up as separate sail entries.

What does the sail time distribution heatmap show?

The sail time distribution is a heatmap showing where you spent the most time during a race. Colors indicate duration (red = longest time) at particular combinations of true wind angle (TWA) and true wind speed (TWS). This helps you understand sailing patterns and identify where you may have spent the most time.

What is the difference between sailed distance, distance over ground, and leg distance?

Leg distance is the direct straight-line (geographic) distance between marks. Sailed distance is calculated from boat speed (STW) multiplied by time -- the distance through water. Distance over ground (DoG) is the GPS-based distance actually traveled. Both sailed distance and DoG are calculated by summing each 1-second interval. The difference between them reflects the effect of current. In the Analyzer, tap the total distance field at the bottom of the map to see the per-leg breakdown.

Can I view live race analytics during a race?

Yes. The Analyzer has a Live Data mode. Open the Analyzer's race selection dialog and select the Live Data entry. In live mode, a refresh button in the top right corner lets you update the analytics display with current data while racing.

What do the up/down fractions in the sail statistics view represent?

The up/down fractions show what proportion of total race time you spent sailing within your target angles for upwind and downwind legs. Upwind time is counted when within +/- 5 degrees of target TWA, downwind when within +/- 10 degrees. On a symmetric windward/leeward course with perfect angles, each fraction would be around 25%. In practice, values around 20% are typical.

What are the different ways to analyze race data in Tactiqs?

Tactiqs provides two analysis options: (1) The in-app Analyzer, designed for quick visualization during and right after racing (including a Live Data mode for real-time analytics during a race). (2) The tactiqs.io web portal, providing detailed race statistics broken down by leg after uploading. The web portal also provides aggregate performance data over time and per-sail performance analysis, helping users understand where improvements can be made in boat/rig setup and sail usage.

Device setup

How does Tactiqs handle heel and pitch data, and how should I mount my device?

Tactiqs can measure heel and pitch using the iOS device's internal accelerometers and gyroscopes without extra hardware. Mount the device securely on a vertical surface using Velcro or a dedicated mount, ensuring it stays firmly in place. Calibrate the zero position after mounting (accessible in the diagnostic page via a long-press on the Wifi/GPS icon). The internal sensors provide accurate attitude data for real-time heel and pitch display. Alternatively, you can use dedicated heel/pitch sensors connected via NMEA (Tactiqs reads NMEA-183 heel/pitch sentences). For compass heading accuracy, mount the device away from magnetic interference. The mounting orientation matters -- the device needs to be aligned with the boat's centerline for correct heading, heel, and pitch readings.

How do I access the weather overlay and select weather data sources?

Swipe on the right edge of the screen in the Navigation tab to reach the routing/weather module. A second swipe opens the detailed settings, where you can select wind, current, wave, and weather sources. You can have multiple sources selected and switch between them when the weather overlay is active by tapping the source name in the bottom left of the chart area. If the weather button is greyed out, you likely do not have a source selected. Tidal data details are available by tapping on any tidal icon on the chart while the forecast overlay is active.

What does the 'Use only apparent wind data' setting do?

With this setting enabled, Tactiqs ignores any TWA/TWS (True Wind Angle/Speed) data from your instruments and calculates true wind internally from apparent wind and boat speed. TWD (True Wind Direction) is then derived from heading and the calculated TWA.

What do the Advanced Settings in Tactiqs control?

The Advanced Settings provide access to some advanced features (e.g. force a device to run in client mode), customization of how Tactiqs processes data and transmits performance metrics back to the boat network, including: Disabling GPS Filtering to use raw GPS data, NMEA Receive Settings to select which sentences to use for GPS, speed, or wind data, NMEA Transmit Settings to send Tactiqs metrics back to instruments, use SOG as STW to substitute GPS speed for boat speed (e.g. if you paddle wheel is not functioning), custom NMEA Talker ID for non-standard hardware configurations, speed dampening to smooth speed readings, or Speed - Filter Zero-Readings to clean up intermittent zero readings from faulty paddle wheels. If there is a specific setting that is not working as you expect, please contact us at info@marineventures.io.

How does the master/client multi-device setup work in Tactiqs?

Tactiqs supports running on multiple devices simultaneously (iPads, iPhones, Apple watches, Maverick AR glasses). The first iOS/iPadOS device to run Tactiqs becomes the master performing the metrics calculation and creating the race log; others automatically become repeater/client displays providing access to all Tactiqs metrics, and allowing to remote control the app, e.g. the start timer, setting the line ends, etc.). All devices must be on the same WiFi network. The 'Force Client Mode' advanced setting will make a device always act as a client, this is very useful if you have crew members running their devices as personal remote displays, and you want to ensure that your dedicated master device is always running as the master. Race logs are only stored on the master device, after uploading the race log from the master device you can create a share code to provide access for your crew or friends to the race data and replay.

Does Tactiqs drain the battery quickly? How long does it last?

On the master device, continuous network usage and keeping the screen on drains the battery more than applications that are used occasionally. Depending on your model, you can expect approximately 3-4 hours of battery life on an iPad or iPhone, with slightly shorter times for devices that have XDR displays in full sunlight conditions (while they are brighter and easier to read, they also consume more power). For longer days of racing, it is recommended to keep the device plugged into a charger or connected to a portable travel battery via the device's Lightning or USB-C connector.

Is Tactiqs available on Android?

No. Tactiqs is iOS/iPadOS-only (iPhone and iPad).

Which iPhone or iPad should I use with Tactiqs?

Any iPhone or iPad works if connected to boat instruments via WiFi. For standalone mode (without instruments), you need a Cellular iPad or any iPhone, since WiFi-only iPads lack the GPS receiver - if your WiFi-only iPad shows no GPS position, this is the cause. Tactiqs requires iOS 14 / iPadOS 14 or later. For best on-deck readability, the iPad Pro models with XDR (Ultra Retina) display are recommended for their sunlight visibility. WiFi-only iPads can still be used if a separate GPS source provides position data (via NMEA network or external Bluetooth GPS).

How do I change the distance measurement units in Tactiqs?

Go to the iOS Settings app, then Apps, then Tactiqs. In the Display section, you will find the setting for 'Distance metric unit,' which allows you to choose between feet, yards, and meters.

Can I use both an iPhone and an iPad with the same Tactiqs account?

Yes, the login is a web interface that is device independent. You can use both devices. If you want to use your phone as a second display, turn your iPad on first so it becomes the master device managing the race data and performance metric calculations. Your phone will then automatically discover it and operate as a secondary display, as long as both devices are on the same Wi-Fi network.

Why does Tactiqs require GPS positioning instead of using Wi-Fi or cellular location?

Tactiqs forces GPS-based positioning rather than the blended location that iOS provides by default. On open water more than 1-2 miles from shore, both Wi-Fi triangulation and cellular site triangulation become very inaccurate. The derived sailing data (wind calculations, laylines, start metrics) is susceptible to the position and speed jumps that often occur with blended positioning. By forcing GPS and running established filters to eliminate inherent GPS errors, Tactiqs achieves very smooth inputs and avoids noise in calculated data. This does mean Wi-Fi-only iPad models require an external GPS receiver.

Can Tactiqs work without boat instruments (standalone mode)?

Yes. Tactiqs works on any size sailboat, from dinghies without instruments to fully equipped racing boats. In standalone mode, the app uses the device's internal GPS for position and speed, and the internal compass and accelerometers for heading, heel, and pitch. You need a Cellular iPad or any iPhone for GPS. For wind data without full instruments, the Calypso Instruments Bluetooth ultrasonic wind sensor is a small, solar-powered option ideal for boats that do not have traditional wind instruments. GPS-derived wind data is less accurate than real instruments but still provides useful tactical information. The Basic subscription tier ($99.95/year) supports standalone mode with internal sensors and Bluetooth wind sensors.

How does demo mode work, and how do I exit it?

Demo mode replays a recorded race log so you can explore all features without a boat instrument connection. The app starts in demo mode by default after you install it. To exit demo mode, go to iOS Settings > Tactiqs and turn Demo Mode OFF. In demo mode, the start line and course positions correspond to the recorded data and will not match your actual location -- this is expected. All Tactiqs features except the race upload are available in demo mode, so you can experience the app when not on a boat.

What display layouts are available in the Tactiqs app?

Tactiqs offers multiple display layouts depending on your device and orientation. On iPhone, you can display 4 or 6 configurable data fields. On iPad, layouts range from 6 to 8 fields in landscape mode. In portrait (vertical) orientation you can choose 5 metrics, and on iPad a MAXI layout shows just 3 large numbers, ideal for mast-mounted displays where readability at a distance is important. You can switch between layouts by swiping from the right edge of the screen while in RACE mode. Long-press any data field to change the metric it displays. The app remembers your metric selections individually for each layout.

Can I use an iPad as a mast display with Tactiqs?

Yes, you can mount an iPad on the mast in either portrait or landscape orientation. In portrait mode, the MAXI layout shows 3 large numbers well-suited for mast viewing. For best sunlight readability, use an iPad Pro with the XDR (Ultra Retina) backlight, which is fully sunlight-capable. An alternative approach is to keep the iPad in the cockpit for the navigator/tactician and mount Garmin GNX120 displays on the mast. Tactiqs can send all calculated metrics to GNX120 units, including custom values like distance to line, time to burn, and time to layline.

Can I use negative values for manually entered custom metrics in Tactiqs?

Yes, the system supports negative values for manually entered metrics. You can use negative numbers in the discrete list format, or set a range that starts below zero.

Where should I place a load sensor for monitoring headsail trim on structured luff or Helix designs?

If you are using Helix or structured luff sail designs, luff tension is the key number for trimming purposes. For Helix-type sails, place the load sensor on the cunningham, as the tack load really defines the sail shape and is the number you want to trim to. For structured luff code sails, place the sensor on the tack rather than the furler.

How do I calibrate my boat speed sensor?

Go out during calm, no-wind conditions at slack tide and do several runs up and down between two points of known distance (at least half a mile apart) under engine. After the first round trip, compare the distance through water reading to the actual distance (times two) and calculate the calibration factor. Do additional runs to verify. Your instrument system's manual has instructions for entering the calibration factor. If your instruments do not support speed calibration, you can long-press the Wifi/GPS status icon to get to the diagnostics page and access Tactiqs speed calibration there - please note that in this case only the speed shown in the Tactiqs app will be corrected, your instrument displays will still show the original uncalibrated value.

Does Tactiqs calculate True Wind Direction (TWD), and is it displayed in magnetic or true north?

Tactiqs calculates TWD from TWA (True Wind Angle) and heading from your instruments. By default, TWD is displayed in magnetic north. This can be changed in the settings if you prefer true north, though most users work with magnetic TWD to keep it consistent with their compass heading.

What do the GPS accuracy indicator colors mean in Tactiqs?

The GPS indicator uses a color system: red means poor accuracy, yellow means accuracy is less than approximately 100 meters, and gray means the position is accurate to within a few meters. Tactiqs checks GPS accuracy before using the data to ensure reliable positioning.

What do the status indicator bars at the top of the screen mean?

The stack of bars at the top of the screen indicates your device's battery level, gray means the device is charging, red means it is not connected to a charger.

Subscription and trial info

How do I sync my Tactiqs account data to my iOS device?

Open the app, go to the Setup tab, log in with your tactiqs.io credentials, and tap Sync. This transfers your boat configuration, VPP data, courses, regattas, marks, and subscription status to the device. Changes made on the tactiqs.io web portal (such as new courses, updated VPPs, or subscription renewals) require a manual sync to appear on the device. The device stores configuration locally and only updates during a sync. The app does not autonomously connect to the Tactiqs server to ensure compliance with RRS Rule 41 (external assistance).

What are the Tactiqs subscription plans, pricing, and trial?

Tactiqs offers a 45-day free trial with no feature limitations and no automatic charge at the end. Subscription plans: Basic ($99.95/year) supports internal iOS sensors and compatible Bluetooth wind sensors (like Calypso), using the device's GPS and compass for performance data. Regular ($199.95/year) adds support for full NMEA instrument systems over WiFi, VPP management, polar-based performance metrics, and detailed analytics including per-sail performance analysis. To purchase after the trial, log into tactiqs.io, go to My Account, and pay via PayPal. There is no automatic renewal -- you must manually renew. After renewal, sync your device to update the subscription status. The app can always be explored in demo mode for free (accessible in the app settings).

Do I need to create an account and log in to use Tactiqs?

Yes, you need to create an account on tactiqs.io and log in via the Setup tab. Tactiqs offers a 6-week free trial with full functionality. If you don't have a boat accessible to test with (e.g. during winter) you can also explore the app's functionality in demo mode, which replays the NMEA data of a built-in race-log.

What chart options are available in Tactiqs?

Tactiqs supports Navionics charts (via Navionics Boating App subscriptions) as the primary chart layer in the Navigate tab. Raster charts are supported to supply your own chart files by copying them into the Tactiqs application folder. Upon app launch it check for new raster files.

What is Tactiqs and how do I purchase it?

Tactiqs is an iOS app for iPhone and iPad that analyzes sailboat performance. It works on any size sailboat, from dinghies without instruments to grand-prix racing boats. Features include race start optimization, tactical decisions (when to tack, which sail to use), weather routing, real-time and post-race performance analysis, sail inventory tracking, VPP polar building, and marine chart navigation. To purchase, go to tactiqs.io, log into your account, go to My Account, and purchase a subscription. Download the app from the App Store and try it in demo mode before purchasing - we offer a fully functional 45 day trial period.

What is the difference between the 'Internal iOS Sensors only' setting in the boat setup versus the regular subscription?

The 'Internal iOS Sensors only' checkbox in the boat setup page on the web portal pertains to the subscription tier for boats without instruments. If you plan to use Tactiqs with data from your boat's instrument system, subscribe to the regular tier.

Troubleshooting common issues

What should I do if Tactiqs shows no boat speed and the true wind direction (TWD) reads as zero?

Tactiqs always calculates TWD itself from the available sensor data. Without boat speed as a critical input, TWD cannot be computed correctly. As a workaround, go to the Advanced settings (iOS Settings > Apps > Tactiqs > Advanced) and enable 'Use SOG for Speed' to use GPS speed over ground instead of speed through water. Note that this cannot account for current, so if you sail in areas with significant current, the layline calculations will be less accurate. When both STW and SOG are available, Tactiqs adjusts laylines for current automatically.

Why are my laylines, VMG performance, or time-to-burn values not showing during a race?

These metrics require VPP data to be loaded for your boat. Ensure you have selected your boat type with VPP polars on tactiqs.io and synced to your device. For time-to-burn, both the starting line must be set (by pinging both ends) and VPP data must be loaded. If you see dashes instead of values, check that you have valid wind and speed data coming in, and that a course or starting line is properly configured. A red circle with 'VPP' inside next to the status icons indicates missing VPP data.

The H5000 WebSocket connection keeps disconnecting. What could be wrong?

The H5000 only supports one WebSocket client at a time. Make sure no other devices or apps are connected to the WebSocket simultaneously. You can also use the embedded browser view in Tactiqs diagnostics (swipe from the right edge in the diagnostics view) to access the H5000 system page and verify the connection status. Additionally, check that iOS's Private Wi-Fi Address feature is turned off for your boat's network (iOS Settings > Wi-Fi > tap info symbol for your network), and consider adding a static IP assignment for the B&G processor's MAC address in your router. The H5000's default IP address is 192.168.0.2.

How do I upload race data and troubleshoot 'no data available' issues?

After racing, open the Analyzer tab and select your race logs for uploading by clicking on the upload arrow in the top right. During the next Sync operation in Setup, logs are uploaded to tactiqs.io where you can access track metrics, sail heatmaps, dynamic VPPs, and detailed maneuver metrics from any browser. If your data shows 'No Details' or 'no data available' after uploading, most likely the upload process was interrupted and the track data on the server is incomplete. You can force a re-upload by long-pressing the upload button for that race in the Analyzer, then syncing again.

My device shows a 169.254.x.x IP address and I cannot receive NMEA data. What is wrong?

A 169.254.x.x IP address is a self-assigned address, which indicates that Wi-Fi address assignment (DHCP) is not working properly. Check the networking setup on your Wifi acces point, NMEA gateway, chartplotter or instrument processor to find its DHCP configuration. Refer to the manufacturer's documentation on how to configure your local network settings.

How do I get started with Tactiqs?

Download the Tactiqs app from the iOS App Store. Upon first launch, the app starts in demo mode, replaying a pre-recorded race so you can explore features immediately. The initial demo dialog allows you to launch the setup wizard to change the app configuration to connect to your instruments or run standalone based on iOS sensors for GPS and heading. To go racing: (1) Create your account at tactiqs.io (includes a 45-day free trial with no feature limitations) and set your region. (2) Set up your boat details, including hull number (a unique identifier, typically 10-15 digits from your registration), GPS antenna offset from the bow (for accurate start line distance calculations), and VPP polars. (3) Create race courses and marks, or select participation in existing regattas set up for your region. (4) In the Tactiqs app, go to SETUP (left-edge swipe), log in, and press Sync to download your configuration. The user manual is available at tactiqs.io/support.

My subscription shows as expired on my device even though I renewed. What should I do?

After renewing your subscription on tactiqs.io, you need to sync your device to get the new expiration date set on your device. Go to the Setup tab in the Tactiqs app and tap Sync to update your device with the current subscription status.

My external Bluetooth GPS receiver is not working properly with Tactiqs. What should I check?

First, make sure no other GPS app is running at the same time, as some GPS apps keep a separate connection to the receiver that can interfere. Set the NMEA data source to 'TCP + Internal' in the Tactiqs settings. Test outdoors with a clear view of the sky, as Tactiqs requires a minimum GPS fix quality for reliable navigation data. Try turning Wi-Fi off on the iPad and leaving only Bluetooth on -- this prevents iOS from falling back to Wi-Fi triangulation, which produces inaccurate position data. Pair the receiver, verify it works in another app like Google Maps first, then open Tactiqs.

Tactiqs is receiving NMEA sentences but not using the instrument data. What could be wrong?

There are two common possibilities. First, the NMEA sentences may have a non-standard two-letter talker ID prefix. You can add custom prefixes under iOS Settings > Apps > Tactiqs > Advanced > Custom Talker ID. The standard supported prefixes include GL (Glonass), GN (GPS+Glonass), GP (GPS), II (Integrated instruments), IN (Integrated navigation), WI (Wind instruments), SD (Depth sounder), and others. Second, some required data may be missing. To run off instrument data, the app needs at minimum GPS data, heading, and speed. Wind information will be used if present. Also check that the NMEA sentences include checksums -- valid NMEA-183 sentences should end with an asterisk (*) followed by a two-digit hexadecimal checksum. Check your gateway's configuration for a setting like 'Send NMEA-183 checksums.'

Can I use GPS speed (SOG) as a substitute for boat speed (STW)?

Yes. The 'Use SOG as STW' setting in Tactiqs replaces boat speed with GPS-derived speed over ground in all calculations. This is useful when your boat speed sensor is not working or not installed. Note that SOG includes current effects, so VMG and performance calculations will reflect speed over ground rather than speed through water.

What should I do if my compass heading data appears incorrect in Tactiqs but displays correctly on my boat instruments?

If your onboard displays show correct heading but Tactiqs shows incorrect values, the issue is likely between your boat's instrument network and the NMEA gateway. Check what device is generating the heading information and how data is routed to the gateway. A non-NMEA-compliant node in your network (such as a PC running navigation software) can corrupt heading values. As a temporary workaround, go to iOS Settings > Tactiqs > Advanced and enable 'Use COG as Heading' to ignore the compass readings.

I get a 'Boat already exists' error when trying to register my boat. What should I do?

Tactiqs requires the hull number to be unique to allow boats to transfer between owners. Sometimes users enter a simple number like '0001' that is already in the system. Make sure you enter your boat's actual hull number. If you did enter the correct hull number and still get the error, contact support -- it may be that a previous owner registered the boat, and the team can look into it for you.

My boat speed readings show intermittent zeros. What is causing this?

Common causes include a weak magnet in the paddle wheel (causing some rotations to go undetected), a faulty wire connection, or two speed sensors on the same NMEA network sending conflicting data. A 'Speed - Filter Zero-Readings' option is available under iOS Settings > Tactiqs > Advanced Settings to filter out these intermittent zeros.

My instrument gateway is connected but GPS data is not showing up. Can I still use the app?

Yes. Set the NMEA data source to your network connection type (TCP or UDP) for instrument data, and set the GPS source to 'Internal.' The app will combine your boat's instrument data with the device's built-in GPS. This requires an iPhone or an iPad with a cellular modem (no active data plan needed). If GPS sentences are present on your network but not appearing, your GPS receiver may use a non-standard talker ID. Add a custom talker ID in iOS Settings > Tactiqs > Advanced > NMEA Receive Settings.

AR glasses and smartwatch support

Do I need an SDK or API key to use the AR glasses with Tactiqs?

No. The Tactiqs app has a license key for the AR glasses built in, so they work automatically without any developer SDK setup or API key registration.

Does Tactiqs support smartwatches?

Yes. Tactiqs supports Apple watches as repeater displays and remote control for the start timer and line end pinging. Please note that Apple only supports pairing their watches with iPhones, not with iPads. If you are using an iPad as your Tactiqs master device, simply run Tactiqs on your phone in client mode, and it will relay the data and commands between your watch and the iPad.

What AR glasses are compatible with Tactiqs, and how do I set them up?

Tactiqs supports the Everysight Maverick AR glasses (the Raptor was the original model, now discontinued). The Maverick is the next-generation platform which is fully supported by Tactiqs. The glasses connect to your iOS device via Bluetooth. They display configurable sailing metrics, bird's eye views of the starting area and next mark laylines, a guidance display, and an aviation-style summary view that will be familiar to pilots. Detailed instructions for the glasses are in the Tactiqs user manual. The AR glasses are purchased separately from the Tactiqs subscription at www.everysight.com.

Race course creation and management

Can I use the same mark more than once when building an ad-hoc course?

Marks from the database can be used multiple times in an ad-hoc course. However, newly-created numbered waypoints that are created as part of the course creation process are unique and cannot be reused within the same course. If you need to round the same point twice, use a pre-existing mark rather than a waypoints, or, if pressed for time, add second waypoint next to the first one.

How do I create, manage, and select race courses in Tactiqs?

Courses can be created on the tactiqs.io web portal or directly in the app. On the portal, create a regatta for your region and add courses to it -- courses appear in the app after syncing. Note that only courses belonging to regattas that you select the participation checkbox for are synced to your device. In the app, tap Select Course on the start screen. Choose 'Ad hoc' to create a one-off course by adding marks (from pre-configured marks, explicit lat/lon positions, or relative offsets). Swipe a mark left to delete it; the icon to the right sets port/starboard rounding. Courses can be defined as windward/leeward with geometric marks, Olympic triangle, or with specific waypoints. For coastal races, the Navigate module supports adding waypoints between marks for controlling more granular route segments. The finish line has an option to be set to the same as the start line, in which case it will be dynamically determined by the start line ends you pinged at t he beginning of the race.

How do I create offset marks in Tactiqs?

In the iPad version go to the Navigate tab and select EDIT for the current course. Long-press the mark that you want to to create an offset mark for, then use the compass rose widget to set both angle and distance from the reference mark. Alternatively, in both iPhone and iPad versions, use the ad-hoc course editor, select 'Relative' when adding a mark, choose the reference mark, then set the bearing and distance.

How do I create, enter coordinates for, and manage marks in Tactiqs?

Marks can be created on tactiqs.io or in the app i the Setup tab. Enter coordinates in degrees and decimal minutes format in the separate degree and minute form fields(e.g., 41 / 23.456, 72 / 05.789), or in fractional degrees (e.g. 41.3909, 72.09648). Note that southern latitudes and western longitudes are indicated with a negative degree value. Marks not defined as 'permanent' in the Mark creation dialog will appear yellow in the Quick Course mark list. Such marks, which are typically at estimated locations, can be pinged by long-pressing the mark in the Quick View when passing them for the first time. The confirmed mark's position wil be remembered in the app for the remainder of the day.

Does Tactiqs require cellular or Internet connectivity during a race?

No. You do not need cellular connectivity or internet to run Tactiqs during a race. Internet connectivity is only needed when you sync your device with your account to download regatta and course settings, or to upload race logs. The app uses an explicit sync model to ensure compliance with racing rules regarding external help -- no external data sources are allowed between prep and finish. Tactiqs caches weather data, so if you calculate a route while connected to the internet during pre-race preparation, you can run subsequent routes without internet access.

If I finish a race and start a new timer for the next race, do I need to set the course again?

Yes. When you press the Finish button, it completes both the race and the course. If you start another timer for a subsequent race, you need to set the course again as well, since back-to-back races would not necessarily use the same course. You can verify that a course is active by checking for the mark list widget on the Race page. If you set up a windward/leeward or olympic course, the weather mark bearing and distance will be remembered for the race day.

Does Tactiqs support course planning with wind angles?

Yes. You can set a course based on waypoints, marks, or windward/leeward definitions. Swiping up on the wind graph twice shows a course overview with wind angles along each leg based on current instrument input, helping with sail planning. You can also manually change expected wind direction and speed for what-if scenarios. With the weather routing module you can also set the starting time for inshore racing at the bottom center and see the predicted leg conditions, or for offshore races have Tactiqs calculate the optimum route. The weather routing menu is accessible via a right edge swipe in the Navigate module.

Can I bulk-import race marks into Tactiqs?

There is no self-serve bulk upload option because mark lists come in many different formats. However, if you send a GPX file, waypoint export from navigation software like Expedition, or an Excel spreadsheet with your marks to the Tactiqs support team, they can help import them for you.

During a race

How do I synchronize the race start timer with my B&G H5000 system?

In the Tactiqs advanced settings, enable 'Transmit Start Info' and ensure the B&G WebSocket settings have the start timer control enabled. You must be connecting directly to the H5000 processor via the WebSocket interface (not pulling NMEA data over TCP via a gateway). This functionality requires the Hercules or Performance software version on the H5000. Note that B&G only supports minute-resolution updates for the timer, so the CPU may take the first sub-60-second interval to synchronize. Tactiqs stores the effective start time whenever you begin a countdown and recovers the race timer on an app restart.

Why does Tactiqs use HDM to next mark instead of COG delta to course to next mark?

HDM to next mark incorporates current into the calculation, meaning it shows where you need to point your boat to reach the mark given any surface current.

Can I use both my NMEA instrument Wi-Fi network and internet Wi-Fi (e.g., Starlink) at the same time?

If your iPad has cellular capability, you can turn cellular on and use both Wi-Fi for instruments and cellular for internet simultaneously. If not, you can configure your NMEA gateway (e.g., Yacht Devices) as a client on your internet Wi-Fi network (e.g., Starlink). On the YD setup page, go to 'WiFi-Client' and enter the Starlink Wi-Fi network name and password. Check the 'Use static address' field and pick an IP address from the Starlink network that is unlikely to conflict (e.g., if your router is at 192.168.1.1, set the gateway to something like 192.168.1.199). Then set that same address as the TCP Server Address in the Tactiqs settings. This way your iPad connects to the Starlink Wi-Fi and can still see the YD gateway as a data source. If you have to switch your iOS device between a Internet provider and your local boat Wifi, remember to restart the Tactiqs app when you change networks. Any ongoing start sequence or race persists across app restarts, so you don't loos your start setup or race data.

How do I set up the start line and how does time-to-burn work?

Set the starting line by pinging both ends from the water when your GPS antenna is lined up with the boat/pin. Based on the GPS antenna-to-bow distance configured in your boat setup and your relative angle to the line Tactiqs calculates where your bow is relative to the line for all line-specific metrics. Three dashes between the boat and pin buttons indicate neither end is set; two dashes mean one end is set; after both are set you see wind bias, distance to line, time-to-line, and time-to-burn. Time-to-burn equals start time minus time-to-line. Unlike apps that use current speed, Tactiqs calculates time-to-line based on your VPPs and includes additional time if you need to turn around (tack or gybe), making it more accurate during pre-start maneuvering. Start lines can be set up on tactiqs.io to include fixed line ends such as a marker or specific location on land paired with a boat or pin for the other side. In the advanced settings, you can also adjust the polar penalty applied to pre-start target speeds due to frequent maneuvering and the wind shadows at a crowded line. The default performance is set to 90% which has proven well for many start situations, and you can adjust the pre-start polar factor for your specific conditions.

Does Tactiqs support tide and current data?

Yes - during a race, Tactiqs determines current from live instrument data (COD/SOG versus Heading/Speed through Water)during sailing and corrects start timing and laylines based on the measured current. For pre-race planning, you can specify current direction and strength that will be factored into leg time estimates. With the weather add-on, current GRIBs are used to factor in when performing weather routing for longer distance courses.

Does the race recording start automatically when I cross the start line?

Race logging is triggered by the race timer. It starts recording at 4 minutes before the scheduled start time. The finish is triggered either by passing the last mark of a set course, or by manually hitting the Finish button. If marks in your course are passed at a significant distance, the app may not automatically advance through the mark sequence, preventing an automatic finish. If a mark is not automatically recognized as rounded, you can long-press the next actual mark in the Quick Course View, or use the 'advance mark' option on the Watch OS and the AR Glasses versions of Tactiqs.

How do I record training sessions or practice sailing in Tactiqs?

Open Tactiqs, press 'Select Course', choose 'Training' and select a training type (Boat Handling, Sail Trim, etc.). Press 'Start' to begin (automatic 3-second countdown, then recording starts), press 'FINISH' when finished. The handling versus trim categories do not influence any metrics calculation, they are intended to help you identify specific training sessions in the analyzer and on tactiqs.io.

Can Tactiqs run in the background, and what happens if it gets backgrounded?

Tactiqs should stay in the foreground during racing for best results. The screen stays on automatically during a race. If the app goes into the background briefly (e.g., switching to another app to check a message), the app continues to receive instrument data for about 30 seconds. If the time in the background is longer, the app will resume the race log upon being back in the foreground, but race data for that period will be missing. If any marks were passed while Tactiqs was in the background, you will need to adjust the actual next mark in the course quick view after wake-up as the app could not track the mark passing. For users with the Maverick AR glasses the bluetooth connection will be maintained in the background, so if you are using the glasses, Tactiqs can be placed into the background.

Does Tactiqs show wind shift information and time to laylines during a race?

Yes, Tactiqs shows time splits to laylines and wind direction and speed history. It also provides a single lift/header metric value, which is the current wind direction compared against the average over the wind graph window. This value is corrected for upwind/downwind and tacks, so a positive number (shown in green) means you are lifted upwind resp. headed downwind, indicating you are on the better tack or gybe.

Is pursuit race start timer based on GPS time or iOS device time?

The race start timer and elapsed race time are based on iOS system time, not GPS input. iOS system time is based on the same official time signal that is used within the GPS system.

How do I switch between Start mode and Performance mode in the app?

Swipe up across the numerical fields on the left side to switch to START mode (timer and line setup). Swipe down to return to PERFORMANCE mode. You can also swipe vertically across the wind graph to toggle between the bird's eye view (showing start line and laylines) and the standard wind display. Long-press any numerical field to customize which metric it shows.

What do the TWA delta and lift/header indicators mean during a race?

The TWA delta shows the difference between your current True Wind Angle and the optimal angle from your VPP polars. The lift/header indicator shows wind shifts relative to the average wind direction over the wind graph duration (by default 15 minutes) -- the lift-header metric is very helpful to know when to tack, often the first header is still within the lifted range, and you can determine the right time to tack when you fall below the average wind direction.
