Essential Racing Metrics on Your Wrist

Stay informed without losing focus. Get instant, glanceable access to your most vital data:

Real-Time Speed: Track your current boatspeed in knots, mph, or km/h.

Average & Max Speed: Monitor your session's performance and push for a new personal best.

Precise Heading: See your current course and the bearing to your next waypoint.

Distance to the mark: Know exactly how far you have to go.

Seamless Waypoint Navigation

Plan your course on your iPhone and sync it directly to your watch.

Disabled waypoints will be skipped when automatically going to the next waypoint.
