Velocity Made on Course

Real-time VMC (speed to destination) + SOG, Bearing, Distance & Angle. Tap for waypoints, optimize tacks/gybes. Now with Apple Watch support and background operation.

Trimming your sails for speed is one thing; finding the fastest course to your destination is another. That’s where Velocity Made Good on Course (VMC) comes in—it tells you exactly how quickly you’re closing on your waypoint. VMC isn’t constant: as you move, the angle between your course over ground and the bearing to your target shifts, so your effective speed toward the mark keeps changing. With this app, just tap your destination on the map and your VMC will update in real time. Use it to choose how close-hauled or how deep to sail for maximum efficiency—essential insight for cruisers and racers alike.
