Here is my entry, "The Oracle" I love this boat. The remote controlled sailboat I built. I grew up sailing real yachts and this became a hobby, The whole family sails, we belong to a RC Yacht club that holds regular races once a month. This is a class I Designed and built. It is called the AoneD RC Yacht. (America One Design) I had a lot of fun building this yacht. It is completely wind powered, there is no engine, it is only powered by winches, servos, and wind. Oh, and batteries for the remote of course.
