It is claimed 404 of masthead rigged sloops were made. The standard arrangement has a small galley aft and settees/berths port and starboard. Their hulls, like most early fiberglassboat hulls, are known for being significantly thicker than more modern fiberglass construction with alternating layers of 1.5 oz. fiberglass mat and 24 oz. woven roving. The full shoal-draft keel has a 4250 lb. lead ballast embedded into it with a displacement of 10,300 - 12,600 lbs.
