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.
