From John, Truelove39@aol.com: I think the fact that no one is voyaging in a power cat (or are they?) makes quite a statement. If all of the wonderful advantages of cat hulls are really true, why hasn't this taken hold?

Just heresay, but probably not going to show up in the towing tank, eh? Brian replied: You are right here. There are a significant number of cats that slam, particularly when they get overloaded.
