Carl,
What about the Richard Roque designs -- aren't they supposed to be planing hulls? And what about that one-off Holder design that Randy Smyth was supposed to use one year in the Worrell back in the 1980's. I believe those were supposed to be planing hulls. Unfortunately, the boat broke (main beam, I think, wasn't it?) on the first leg, so it never got a chance to show what it could do. I thought it was a beautiful boat. I wonder what happened to it.
