Several hundred Optimists packed along a start line, seen from above

Your whole fleet.
One live map.

Sailors bring their own pucks. The club owns one base station. The race committee gets the line, the start and the finish, called in centimetres.

Zero work at the race office.

No rental desk, no device handout, no charging crates. Every sailor owns and charges their own puck. The organiser enables tracking for the event and the fleet appears on the map.

The line pings itself

A puck on the committee boat and one on the pin broadcast the line to every boat, live. Move the pin, and the line moves with it.

The over-early list, seconds after the gun

Each puck decides on board whether any part of the hull was over. The race control app shows the list with distance per boat.

Finishes scored as they happen

Close finishes recorded to the centimetre and written straight into the results. Fewer scoring inquiries, fewer redress hearings.

Families and coaches follow live

Every boat on one map, ashore and in the coach RIB. Full replay of every leg for the evening debrief.

The decision is made on each puck, so the start does not get harder with more boats. The committee sees one fleet on one screen.

The club plugs in one base station. The fleet gets RTK.

RTK needs a fixed reference nearby. The club owns one, mounts it once, and connects power and internet. Corrections reach every puck on the water.

The club owns the base.
The sailors own the pucks.

Club pricing is confirmed with pilot clubs. Sailors pay €199 for the puck and €5 a month in the months they race.

Put your fleet on the
start line in 2027.

We are looking for dinghy clubs and class associations to run the pilot: a base station at the club, pucks on the boats, real starts at real regattas. Email your club name, your role, approximate sailor numbers and the regattas you have in mind.

Base-station pricing and pilot terms are confirmed with pilot clubs. Built in Sweden.
