The South Coast 21 is a recreational keelboat designed by Carl Alberg and first built in 1965.[1][2][3]
The boat was later developed into the slightly longer, swing keel South Coast 22.[4]
The design was built by South Coast Seacraft in the United States, between 1965 and 1979, with 300 boats completed, but it is now out of production.[1][3][5]
The boat was produced complete and ready-to-sail and also as a kit for amateur completion.[1]
Design
The South Coast 21 is a recreational keelboat, built predominantly of fiberglass, with wood trim. It has a fractional sloop with 206.30 sq ft (19.166 m2) of sail area or with an optional masthead sloop rig and 226.38 sq ft (21.031 m2) of sail area. The hull has a spooned, raked stem; a raised counter, angled transom, an internally mounted spade-type rudder controlled by a tiller and a fixed fin keel. It displaces 2,000 lb (907 kg) and carries 625 lb (283 kg) of ballast.[1][3]
The boat has a draft of 3.00 ft (0.91 m) with the standard keel.[1][3]
The boat is normally fitted with a small 3 to 6 hp (2 to 4 kW) outboard motor for docking and maneuvering.[1][3]
The design has sleeping accommodation for two people, with two straight settee berths in the main cabin. There are no provisions or space for a galley or a head. Cabin headroom is 39 in (99 cm).[1][3]
The design was changed during production to address issues that became apparent in service. Starting with hull number 91 the keel was moved aft to reduce weather helm. This did not entirely solve the issue and later the rudder was enlarged as well.[1]
The design has a PHRF racing average handicap of 252 and a hull speed of 5.1 kn (9.4 km/h).[3]
