My photos are still in the Other Boat Photo section. They were available with either 100% balsa coring or balsa only in the hull sides/deck with a solid glass bottom. The liner was the stringer system. All V-24 hulls (Seabird's name although the hull measures 23' 3" LOA) could accept different configurations with bolt-on deck caps. Very similar to the Formula 233 hull but designed by a different guy in the racing community (forget the name). With 24 degrees of deadrise, they ride really nice. There is a flat pad in the aft 1/3 of the hull so they can get up out of the water pretty well. Mine had a 225 Johnson which performed admirably - cruise 25-26 knots around 4500rpm and WOT was 35 knots at 5600. I sold mine in August '08 to a gentleman from this area that was taking to the Florida Panhandle where he spends his winters.
