Your Session
Record your session using your Garmin, Apple Watch, or any GPS-enabled fitness tracker. As long as it records a track, we can analyse it.
The Upload
Once you're back on shore, export your data as a GPX or TCX file. Simply drop the file into the KnotNow Sessions dashboard. Our software immediately begins parsing the GPS pings into sailing metrics. Need help? See our upload guide for Garmin, Apple Watch, and more.
The Diagnosis
Within seconds, your performance report is ready.
- Check the Map: Does your track align with the wind?
- Spot Asymmetry: Are your port tacks wider than your starboard ones?
- Review Smoothness: Did you keep your speed through the gybes?
The Professional Edge: "KnotNow doesn't just show you where you went; it shows you why you weren't faster. Use the map, VMG, and port vs starboard breakdown to spot patterns—and start fixing the habits you didn't know you had."
