I don’t know yet what design, but I have always said that a catamaran with keels is the worst possible craft to run aground in.
On a mono, the crew can kedge off of the top of the mast. I’ve been there. On a tri, the slackers can all be ordered onto the ama.
A cat with keels is a whole difference scenario, and better hope that you don’t get neaped. A cat with boards can stop, determine the way back out, lift the boards, and flee back. Keels don’t allow that. Thats part of why I prefer boards, among all the other reasons from pointing better to being able to perform repairs while underway.
