Oh that's right SD, with a tri-hull, you have built-in flopper stoppers. Aside from the speed advantage, that's one of a multi-hull's best attributes.
Did you see the video in the Gunboat site yet? They claim a Gunboat 60 has a top speed of 30 kts, shown passing an 80 ft Pugh, which was "only" doing 18 kts.
