Production

The boat was built by Cal Yachts in the United States between 1963 and 1969, but it is now out of production.[1][3]

The design was also built under licence by Calgan Marine in North Vancouver, Canada.[1][4]

A total of 347 examples of the type were completed.[1]

Design

The Cal 28 is a small recreational keelboat, built predominantly of fiberglass. It has a masthead sloop rig, an internally-mounted spade-type rudder and a fixed fin keel. It displaces 6,000 lb (2,722 kg) and carries 2,200 lb (998 kg) of lead ballast.[1]

The boat has a draft of 4.50 ft (1.37 m) with the standard keel fitted.[1]

A Universal Atomic 4 gasoline engine with a "V" drive was a factory option. The fuel tank holds 18 U.S. gallons (68 L; 15 imp gal) and the fresh water tank has a capacity of 28 U.S. gallons (110 L; 23 imp gal).[1]

The boat has a PHRF racing average handicap of 183 with a high of 186 and low of 180. It has a hull speed of 6.36 kn (11.78 km/h).[5]

gollark: I don't do stuff which requires more performance than "common stuff completes in under a few tens of milliseconds", so honestly I'd prefer a GCed language like OCaml over Rust, except Rust actually has good libraries and tooling.
gollark: Macron doesn't seem very good.
gollark: There are some languages I would be happy to use if they had more of an ecosystem. Like OCaml.
gollark: This is what I do, despite no language being truly satisfying.
gollark: You are such a subresource integrity, gnobody.
