Seafarer 31 (Fastnet Yawl)
Description
The Seafarer 31 Fastnet Yawl, designed by McCurdy & Rhodes and built by Seafarer Yachts in Huntington, New York, from 1968 to 1974, is a rare fiberglass cruising yawl variant of the Seafarer 31 sloop, with an estimated ~50 of the ~200 total units featuring a mizzen mast for enhanced balance and offshore versatility. Measuring 31 feet LOA with a 9-foot-10-inch beam, 4-foot-6-inch draft, and 8,500-pound displacement (3,500-pound lead ballast), it boasts a fin keel with skeg-hung rudder, 450 ft² sail area (SA/D ~16.5), and 41% ballast ratio for a comfort ratio of ~25, delivering a dry, stable ride at 5.5–6.5 knots (hull speed ~6.8 knots) in coastal or offshore conditions like the Fastnet Race-inspired passages. Its hand-laid GRP hull, balsa-cored deck, and teak interior house 4–5 berths (V-berth, saloon settees, quarter berth), a galley, and an enclosed head, ideal for family cruising or short-handed PHRF racing (~200–220).
