See the race you just sailed.
SailTrace records from your phone, reconstructs the race, and shows you what happened on the course.
Record
Set up at the dock. Race as usual.
Start recording before the warning signal, put the phone away, and SailTrace captures the whole race on its own. Your replay will be ready when you get in.

For clubs, teams, and coaches
Cover Pro for your whole fleet.
The replays get better with every boat that records the race or practice session. Clubs, teams, class fleets, and event organizers can sponsor Pro for the sailors in their group: one price for a regatta, a clinic, a series, or the season, and every sailor gets the full Pro benefits.
We make it easy to get everyone set up: a custom sign-up link, printable QR codes, and information for your sailing instructions.

Questions before you start.
- What kind of regattas and fleets can use SailTrace?
- One-design fleets, club series, championship regattas, PHRF, junior programs, and high school and college teams.
- Do I need an iPhone?
- Yes. Recording is iOS-only right now. Sailors who don't have an iPhone can still open shared replays after the race on their Android phone or computer though.
- Do I need any gear besides my phone?
- No mounts, no new hardware. Your phone is all you need.
- Does the whole fleet need to use it?
- No. SailTrace is useful even if you're the only one using it. That said, when more boats record a race the replay and stats get even better.
- How accurate is it?
- SailTrace uses advanced recording and processing techniques for race data. While no tracking is perfect we get pretty close.
- How much battery does SailTrace use?
- SailTrace is optimized for battery efficiency, so if your device is charged you should be able to record many hours worth of races.
- Do I need cell service on the water?
- Yes, SailTrace requires a cellular data connection to function. This shouldn't be a problem for most U.S. racing venues.
- Can I use SailTrace outside the United States?
- No. At this time SailTrace is only available in the United States.
