Windsurfing Calculator

Windsurfing Calculator allows calculating windsurfing and kitesurfing equipment (sail, board, fin, kiteboard and kite size) based on the sailor weight, board type and wind speed. The app is a GUI wrapper of the famous Windsurfing and Kitesurfing Calculator of James Douglass. The app has no ads!

Some features are disabled in the free version: favorite sails/kites filtering, advanced fin calculation, mast compatibility chart.
