Dr. Palin (sailing PH.D.), from the Houston area built an all carbon 18sq. He sailed it many years. Not quite sure what it weighed, it was very light and very fast. He trailered it on his pop up camper, broken down. He would rig and break it down all by himself, very quickly I might add.
He sold it at least 4 years ago, don't know where it is now. A spin on that would have been awesome.
Tammy and Jay Klassen bought Dr. Palin's masterpiece and took it to Ocean Springs, MS. It's now available for sale, or was at last report. Dennis told me once that it was just barely under the 330 lb limit; I've race against it quite a few times and it seemed sticky in light air---as soon as a hull started flying tho, look quick - it was GONE!
