Founded by Hollis Metcalf, the South Coast Seacraft Company of Shreveport, Louisiana began production of the SC 23 and SC 21 in 1965. Both Carl Alberg designs. In a effort to capitalized on the emerging trailerable cruising boat market, Metcalf and his chief engineer, James Monroe, redesigned the SC 21 to include larger accommodations and a swing keel, which became the SC 22 and their most successful boat by far with over 3000 produced. In 1975 the company was sold to a group based in Chicago and the plant closed in June of 1981. Over 4,000 South Coast sailboats were produced.
