SailingHelper (v. 1.6.3) Разработано Koert Zeilstra

This application helps you to determine the most optimal direction to sail to by displaying the current speed and direction. It will keep track of your speed and direction to display a graph of speed vs. direction.

You can enter waypoints with GPS coordinates and navigate toward these locations. When you navigate to a destination, the application can display the effective speed in this direction (Velocity Made Good - VMG).
