Well, I've been reading "Catamaran Racing for the 90's" and it says so. <img src="http://www.catsailor.com/forums/images/graemlins/grin.gif" alt="" />

Actually, I can feel the boat accelerate as I move up and get the sterns out of the water (and the gurgling stops). Also, it does point better with the bow tips digging in more, helping the skegs make it go straighter upwind.

Granted, this is light to medium winds, and I weigh a shade over 200; so in heavier winds or with lighter cargo, the difference may not be as noticeable.
