We had a small fleet of 5.5 sloops in Florida a few years back, Tim Bohan and I switched to I20s, Seth Stern and Mike Crawford switched to F16. Greg Henry still has a sloop and Rush Bird still has a uni. You should get in touch with Rush, if he doesn't see your post here try the 1Design.net forum.

The 5.5 sloop for a lighter crew is one of my favorite all time boats. In 15-20 that boat hauled butt.
