The San Juan 21 is a two-to-three-person keelboat with a retractable keel. Like the San Juan 24, the SJ21 was a product of the Clark Boat Company in Washington State. More than 2,600 boats were produced from 1969 to 1985, some at a second facility in North Carolina. Three hull models, known as Mark I, II, and III, offer variance in foredeck and cabin dimensions. Some boats feature large spinnakers in addition to the jib and genoa. With the fractional rig, the boat can be sailed singlehanded. The class has a reputation for basic construction and easy maintenance. In North America, San Juan 21s are raced most heavily in the Pacific Northwest and the southeastern U.S. For more information, read the San Juan 21 Wikipedia article.
