I voted "what's a boat" because although I have been sailing in the past on boats I don't own, it has been aaaaaaaages since I stepped on to one. Unfortunately. I just don't get the opportunity. I've applied for a sponsorship to go sailing on the Leeuwin in June/July this year, though, since I'm too poor to pay the whole thing myself. The Leeuwin is a 55-foot tall ship... I think a brig, but I'm not too crash -hot on my terms. It's three-masted, mostly square rigged, but with some lateens as well. It's used as a sail training ship.
Here's a link, if you want to find out more.
