To be sure the Bay is no place for a "newb" to learn anything, but since a windsurfer and kite board both require more wind, and the Bay has some pretty good wind, that would probably be safer for a newb vs. a new cat on it's side blowing toward the rocks.

I think there are not too many sandy type beaches around the bay as well, but more mud flats at low tide which would be very difficult to pull any cat through.
