Find what mattered.

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.
- 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.
