01 / 04 FEATURE — START

Join a session in seconds.

The coach generates a session code. Sailors enter the same code, pick their sail number, and tap start. No accounts required to join — guest mode lets a sailor on the water connect immediately.

02 / 04 FEATURE — COACH

Broadcast to every sailor.

Set the top mark with one tap at the RIB's position. Send canned messages — STARTING SOON, REGROUP AT RIB, FOLLOW ME — that banner and beep on every sailor's phone. Tag tacks, gybes and wind shifts silently for post-session review.

03 / 04 FEATURE — RACE START

5 · 3 · 1 start.
Every device beeps.

Coach taps a duration, the countdown syncs across the whole fleet via server time. Flag-coloured banner above every screen. Audible sine-wave beeps every minute, every second of the final ten, and a long horn at zero — even with the silent switch on.

04 / 04 FEATURE — COURSE

Lay the course from the RIB.

Point the bow into the wind to capture its direction, pick a shape — windward/leeward, triangle, Opti trapezoid — and the app lays the marks out from the RIB's position. Drag a pin to fine-tune; every sailor's gauges, leg detection, and the race reports follow the move instantly.
