00:00 — Before you start
One thing worth doing, sailed past once.
Highly Recommended
Mark the line
Sail past the boat end and the pin end, tap once at each. GPS coordinates confirmed right on screen. Skip it and your report won't include starting-line performance analytics — there's nothing to measure against.
T+00:00 — The race itself
Then it goes quiet.
Start the five-minute sequence and the countdown runs itself — clear call-outs through your earbuds, so your eyes stay on the fleet, not your phone. Once the gun goes, the app tracks everything in the background: your GPS track, every tack and jibe, every mark rounding — including offset marks, recognized automatically — with no button presses required.
Post-race — Your report
This is where it earns its keep.
-
01
A visual track of the whole race
Plotted from your own GPS data, colored leg by leg.
-
02
Every tack and jibe, analyzed
Boat lengths lost, speed loss, time to recover, and whether the new heading was actually worth it.
-
03
Automatic outlier flags
Any maneuver that cost you noticeably more than your typical one gets called out, so you know exactly where to look.
-
04
A full timeline and starting-line analysis
Exactly how your timing and positioning played out at the gun.
-
05
Trend against your recent races
See whether you're getting better or worse over time, not just how one race went.
-
06
Every metric explained
Right on the report page, a single tap explains every performance metric in detail — what it means and exactly how it's calculated. No guessing what a number is trying to tell you.
Share it in seconds
Get it in front of a coach.
Sync to your race video
If you have a full-length race video uploaded to YouTube, provide the link and enter the video timestamp of the starting signal from the video, and the app syncs every tack, jibe, and mark rounding with your video's actual timeline — ready to paste straight into your YouTube description as clickable chapters, or click straight through from any moment in your report to that exact point in the video.
Send a report straight to your coach
Sending it to Sailboat Instructor is attached and ready to review, right from the app — no exporting, no emailing files around. Prefer a different coach? Download the report or the raw GPX track and send it yourself, however you'd normally share a file.
Built for what actually happens
Real starts get messy. The app keeps up.
General recall? Race abandoned? Discard it with one tap — nothing gets saved, nothing skews your averages. Keep your race history as long as you want, or clear it and start fresh whenever you like.
