CourseSetter

Allows sailing race courses to be quickly and accurately set

This app allows you to pick a predefined sailing race course (Triangle, Trapezoid, ) and rotate/resize it to suit the wind conditions and the area in which the race will be held.

If the standard courses are not sufficient you can define your own and share them.

Once you have set up your course the app will provide steering navigation for you to put the race marks in the desired locations.

Alternatively you can export the course as a GPX file and use a different app for navigation.
