The MacGregor 21 is an American trailerable sailboat that was designed by Roger MacGregor as a racer-cruiser and first built in 1980.[1][2][3][4][5]

The MacGregor 21 is a development of the Venture 21.[1][2][6]

Production

The design was built by MacGregor Yacht Corporation in the United States , from 1980 until 1985, but it is now out of production.[1][2][7][8]

Design

The MacGregor 21 is a recreational keelboat, built predominantly of fiberglass, with wood trim. It has a masthead sloop rig, a spooned raked stem, a slightly angled transom, a transom-hung rudder controlled by a tiller and a retractable swing keel. It displaces 1,175 lb (533 kg) and carries 400 lb (181 kg) of cast iron ballast.[1][2]

The boat has a draft of 5.50 ft (1.68 m) with the swing keel extended and 12 in (30 cm) with it retracted, allowing operation in shallow water or ground transportation on a trailer.[1][2]

The boat is normally fitted with a small 3 to 6 hp (2 to 4 kW) outboard motor for docking and maneuvering.[1][2]

The design has sleeping accommodation for four people, with a double "V"-berth in the bow cabin and two straight settee berths in the main cabin. Cabin headroom is 39 in (99 cm).[1][2]

The design has a PHRF racing average handicap of 252 and a hull speed of 5.8 kn (10.7 km/h).[5]
