Optimize Your Performance with VMG
Make better tactical decisions with live Velocity Made Good (VMG). See exactly how fast you are closing in on your next waypoint and adjust your heading to maximize your efficiency toward the mark.

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.

Compass bearing to the mark: Know which direction on a compass the next waypoint is.

Seamless Waypoint Navigation
Plan your course on your iPhone and sync it directly to your watch. The app automatically transitions to the next waypoint as you round a mark, with haptic feedback to keep you alerted without needing to look at the screen. Disable and optionally hide waypoints. Disabled waypoints will be skipped when automatically going to the next waypoint.
