Good points. Except for a few places, one gets blown onto either mud or rocks. It's a little easier to pull a board out than a cat (except for one unfortunate windsurfer who, I'm told, was killed slipping off some downwind rocks).

But there's a strange thing about the SF Bay. There are lots of dinghies and skiffs and keelers out there, and kites and windsurfers (a superb Formula windsurfing scene) -- but very few cats. Either this is a tremendous untapped market, or there is some special multihull repellent which I don't know about, and which doesn't repel every other sort of sailing craft. Does anybody know what's (not) going on with that?
