Production
The boat was built by Cal Yachts in the United States from 1961 to 1975, but it is now out of production.[1][3]
The Cal 20 was seen by Canadian Al Nairne during a visit to California. Nairne convinced Jack Jensen of Jensen Marine to allow him to produce the Cal 20 under licence in Canada and formed Calgan Marine in North Vancouver for that purpose. Calgan Marine went on to produce many Cal Yachts designs, plus designs of its own.[1][4]
A total of 1,945 Cal 20s were built during its 14-year production run.[1]
Design
The Cal 20 is a small recreational keelboat, built predominantly of fiberglass. It has a fractional sloop rig, a transom-hung rudder and a fixed fin keel with a weighted bulb. It displaces 1,950 lb (885 kg) and carries 900 lb (408 kg) of ballast.[1]
The boat has a draft of 3.33 ft (1.01 m) with the standard keel fitted and is normally fitted with a small outboard motor for docking and maneuvering.[1]
The boat has a PHRF racing average handicap of 279 with a high of 291 and low of 270. It has a hull speed of 5.69 kn (10.54 km/h).[5]
