SailingMetrics

SailingMetrics – Your Complete Sailing Performance Companion Whether you're a competitive racer, club race officer, or coaching the next generation of sailors, SailingMetrics gives you the tools to track, analyse, and improve performance on the water. LIVE METRICS & AUDIO COACHING Stay focused on sailing, not your screen. SailingMetrics reads your key performance numbers aloud so you never need to look down: VMG (Velocity Made Good) – know whether you're sailing fast to the mark Speed Over Ground (SOG) and Course Over Ground (COG) Heel angle with configurable threshold alerts Magnetic heading Configure each metric's announcement frequency independently and tune integration periods to match your sailing style. TACKING TRAINING Improve your upwind technique with automated tack analysis. SailingMetrics detects each tack automatically using GPS track fitting, then calculates the height gained or lost compared to your baseline VMG. After every tack you get instant feedback on your manoeuvre — so you can identify what's costing you distance to windward and fix it in the next tack. Automatic wind direction estimation from your tack angles Pre- and post-tack GPS track capture (10 seconds each side) Height change displayed in metres after every tack Full session history to review your progress GPS TRACKING & RECORDINGS Record your time on the water with continuous background GPS tracking. Review past sessions, upload recordings to your club's backend, and share data for instructor debrief. Background location tracking (no need to keep screen on) Offline recording support Instructor card view for coach-to-sailor sessions Ultrasonic wind sensor integration via Bluetooth SailingMetrics is built for serious sailors who want data-driven improvement. Try it on your next race or training session. Requires location permission for GPS tracking. Background location is used for continuous recording while racing.
