Beverly was a catamaran sailboat designed by MacLear & Harris, built by Cape Cod Shipbuilding and owned by Van Alan Clark Jr.,[1] who won several racing competitions with her in the 1960s.
[1] Beverly took the North American Catamaran Championship title in the 300-square-foot class[1] on August 19-20, 1962.
[2] In the fourth One-of-a-Kind Regatta, sponsored by Yachting magazine, boats of all types competed against each other under a complicated handicap system in the waters of Biscayne Bay, Florida,[3] in February 1963.
Catamarans dominated to such an extent - taking the top ten places in all three races - that organizers decided to name only one overall winner, Beverly, which outclassed the other catamarans.
[3][4] However, she was defeated by Sealion in the 1963 North American Catamaran Championship, held off Marion, Massachusetts.
