What happens when signal drops
The unit keeps recording positions even when it cannot send them, and sends them once coverage returns. During the race you can see that a boat has stopped reporting; in the replay the race appears complete.
How it works
Three steps, and none of them asks you to be technical
Setting up tracking for a race takes less time than setting the course. What follows is everything the club has to do on race day.
A GPS unit on each boat
Small, waterproof and with no wiring: strap it on before launching, collect it when the boat comes back. It touches nothing on the boat and needs no power from it, so it works the same on a patí as on an Optimist.
Set the course
Marks, committee boat and start line are dropped from the race officer’s phone, right there and on the chart. If the wind shifts and a mark has to move, you move it and the system takes it.
Share one link
The same link is the live view during the race and the replay afterwards. Post it in the club’s WhatsApp group and everyone has it — no accounts, no passwords.
What people ask before they try it
Who operates it on race day
One person on the race committee, from a phone. They set the course, start the race and close it. Everyone else — families, sailors, the bar — just opens a link.
Where the data sits
Positions are only visible inside the race window. Outside it nobody from beyond the club can see where any unit is, and that includes TV mode.
What happens when it ends
The race closes and the replay stays available at the same link. Standings, times and tracks can be shared and are still there next season.
