This is a well-designed program with realistic wind characteristics and accurate -- if simple -- tiller and line controls. I especially like the clean graphics and the basic tutorial since I have little experience sailing. The regattas are challenging and the time-keeping encourages you to sail the same course several times in order to improve your skill steering, tacking, and judging when to jibe. Music is appropriately relaxing and the messages and tips are useful. Worth the time to explore and enjoy!
