Why we built RaceZen

Dinghy racing has never been short of technology. It has been short of technology that a club can actually run on a Saturday afternoon without a rigging crew and a budget.

The gap we kept hitting

Sailors already carry a device with GPS, a screen readable in sunlight, and a data connection. What was missing was software that treated that device as a race instrument rather than a phone that happens to log a track.

RaceZen started from that: start line precision, live race status, and a replay worth watching afterwards, all from equipment people already own.

Both sides of the line

Most sailing tech is built for one side of the fleet — either the sailor or the race committee. We built for both, because a start is only fair if the boat and the committee are looking at the same picture.

That means roles across the whole event: sailor, crew, coach, tactician, organiser, volunteer, umpire, parent, spectator, committee boat, course mark, support vessel and base station.

What comes next

Hardware, because a phone needs somewhere to live on a boat. Better tools for clubs, because that is where most racing actually happens. And a shop, so you can get the parts without an email chain.
