The Cal 3-27 is a development of the Cal 2-27, which was in turn a development of the Cal 27.[1]

The Cal 3-27 was also marketed as the Cal 27 Mk III and then later just as the Cal 27.[1]

Production

The boat was built by Cal Yachts/Jensen Marine in the United States between 1983 and 1985, but it is now out of production.[1][3]

Design

The Cal 3-27 is a small recreational keelboat, built predominantly of fiberglass, with wood trim. It has a masthead sloop rig, an inboard motor, an internally-mounted spade-type rudder and a fixed fin keel. It displaces 5,200 lb (2,359 kg) and carries 2,000 lb (907 kg) of ballast.[1]

The boat has a draft of 5.00 ft (1.52 m) with the standard keel and 4.00 ft (1.22 m) with the optional shoal draft keel. A tall mast was also an option with a main sail luff ("P" parameter) 1.5 ft (0.46 m) higher.[1]

The boat has a hull speed of 6.46 kn (11.96 km/h).[4][5][6]
