I do not understand the economical principles behind a sailing vessel. Please explain to me how a boat that doesn't have any engines is cheaper. Is it the gas? Or is wind just cheaper? Can I power my power boat with wind? How does wind make it go? If PNWBrit would be so kind as to explain his infinite boating wisdom to me It would be much appreciated. Also Brit: I haven't forgotten that you want to beat me up and, just to let you know, I'm still very, very frightened.
