Start line decisions, laylines and boat performance on your phone. Try the working app with simulated sailing data today.
Explore a simulated Saint-Tropez start in your browser. No account, Hub or boat instruments are needed for the demo. Apply to join the app beta when you’re ready.
Open the working demo →The Hub is being developed for supported marine instrument networks. Live wind, depth and heading need suitable sensors; calculated tide also needs speed through water and heading. GPS alone does not supply these readings.
Register interest in beta testing →Explore line bias, follow the approach and switch to the upwind leg. This is the working app running a simulation, so you can see how it behaves for yourself.
Sail an upwind leg in the Golfe de Saint-Tropez. Red and green layline corridors show the calculated approach and a conservative margin for changing wind, speed and current.
See your approach in a wind-up view, with tide-corrected laylines, live distance and the countdown together. Check the starboard approach or switch on the port flyer.
Read wind, heading and boat speed on the app’s instrument display. Switch between pages and customise the readings to suit your boat.
See the connection status, available readings and app settings in Systems. The connected Hub shown here is simulated; Tackr Hub hardware is in development.
See wind, speed and start line geometry together, so you can judge your approach without switching between instruments. Live readings depend on the data available from your boat.
The Hub is being developed to connect supported SeaTalk1, NMEA 0183 and NMEA 2000 instruments to Tackr over WiFi. Register your interest in the beta programme; hardware availability and installation will be confirmed for your boat.
For live instrument data, the Hub will need power and a suitable connection to your boat’s supported network. Wiring and connectors vary between SeaTalk1, NMEA 0183 and NMEA 2000.
The Hub creates its own WiFi network on the boat. Any phone, tablet, or laptop within range can connect — no internet required, no cloud dependency, sub-second latency.
Live data streams directly into the Tackr app. Laylines compute from your actual wind. Tide vectors update from your real SOG vs STW. Every number is real, every second.
Depth Alarm is shipping today. The rest is on the roadmap for the 2026 season, prioritised by beta feedback.
Set a depth threshold. Tackr alerts you when a connected sounder reports a depth below your threshold.
One button drops a man overboard marker on the chart with a bearing and distance — instantly visible to helm.
Define an anchor radius. Tackr watches your GPS position and wakes you the moment you start to drag.
Connected to a bilge float switch via NMEA, Tackr alerts you to unexpected water ingress instantly.
