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 — REVIEW

Every session saved for later.

Each sailor's track on a map, peak speed, average speed, detected tacks and gybes, plus every coach note pinned in time and place. Speed chart layers all sailors together. Past sessions stay searchable on every device you sign in on.
