The art of setting and trimming sails has a long and noble history, but when you think about it, it’s an art that exists because of fundamental flaws in the technology. Sails are fixed to a few basic positions that must be carefully tended to translate the impetus of wind into forward motion. Dan Tracy, “an enthusiastic sailor and fisherman from Mount Desert Island, Maine,” took a page from the kiteboarder’s playbook and attached a really big kite to a trimaran. Flying a kite lets him catch higher, steadier winds, from a wider variety of angles, to power his boat. Check him out on your next visit to Hawaii. [treehugger]
