Sailing is a method of solving the various problems involving course, distance, difference of latitude, difference of longitude, and departure.

The app plots on a Google map the route between a departure and a destination point, using the following sailings:
- Rhumb line (loxodromic).
- Great Circle (orthodromic).
And calculates:
- Course & distance.
- Waypoints of the great circle route.
- Save between Rhumb line and Great Circle route.
- Nodes and vertices of the Great Circle.

It also plots the entire Great Circle.
