Start sequence controls

Coach mode is optional. Dinghy Coach works without coach mode, and this page covers the extra tools for coached sessions on the water.

Coach capabilities

Talk to the fleet

Group push-to-talk broadcasts to all sailors. Individual PTT lets you speak to a specific boat. Works with wired or Bluetooth headsets, including media-button toggle.

Set the wind

Capture wind direction from the coach boat using the full-screen compass with live heading and a calibration prompt when sensor accuracy is low.

Place marks

Set Committee Boat, Pin, and up to nine named course marks using GPS-validated positions captured on the coach boat.

Run the sequence

Synchronised 5, 3, or 2-minute start countdowns aligned across all boats using clock-offset sampling. Abort retries automatically to any sailor who hasn't acknowledged.

Coach commands

Send Go Home, Come to Me, or Follow Me overlays to the whole fleet with a tap. Commands show as full-screen alerts on each sailor's device and auto-dismiss after a few seconds.

Monitor the fleet

See live speed telemetry and connection status for each boat at 1 Hz. Acknowledgment indicators show when a start or stop command is still pending on a specific boat.

Speak to sailors instantly

For coached group sessions, give a quick correction, regroup the fleet, or call the next step without shouting across the water. Dinghy Coach includes built-in push-to-talk so the coach can speak to the whole group or to an individual sailor during the session.

Voice notes recorded during the session are transcribed on-device using offline speech recognition and saved with the session — so observations made on the water are waiting in the debrief.

Communication uses local IP transport over Wi-Fi. Coaching does not require internet access and voice audio stays device-to-device.

A simple on-water flow

  1. Open Coach mode

    Switch to coach view to start setting up the session.

  2. Set wind and marks

    Capture wind direction and place committee boat, pin, and course marks.

  3. Talk to sailors, run the sequence, and record notes

    Use push-to-talk to guide sailors. Run synchronised countdowns. Record voice notes during the session — they are transcribed automatically and included in the debrief.

  4. Debrief later with the setup already in place

    Session context carries through automatically to the debrief.

Less setup friction. Better debriefs.

Wind, marks, and session control happen while the session is being run, so the review afterwards starts with more of the important context already in place.

Next steps

Want to see a coached debrief before running your own? Open one of the example sessions below. Coach mode still requires the Android app on the coach boat and a local Wi-Fi hotspot or club network to connect sailors.
