DescriptionDrawing by Bob Miller titled 'Prelim Lines Hyprostatics for 60' Catamaran' designed at Miller at Whitworth about 1970.
HistoryThe design and development of the modern sailing catamaran, widely popular around the world today, began in 1947 when Woody Brown, Rudy Choy and Alfred Kumalae built MANUKAI a modern catamaran based on the ancient Polynesian double hull boats.
Ten years later, spearheaded by Rudy Choy, Alfred Kumalae, and Warren Seaman, in the Hawaiian Islands, ‘C.S.K Catamarans’ was formed in 1957, with plans to build a production of modern catamarans.
The early 1960’s saw the dawn of the modern multihull era, which has continued, and grown stronger, ever since. In 1966 the American actor James Arness (Marshall Matt Dillon on the famous 1960s television show, Gunsmoke.) asked Rudy Choy to design and build him a fast, race winning catamaran. The result was the 60-foot SEASMOKE, launched in 1967 which proved to be a very fast yacht. James Arness entered ‘SEASMOKE’ in the 1968 Multihull Transpac Race which started on July 4th. at Point Fermin off Los Angeles. The yacht proved all the owner had hoped for, winning lines honours and arriving at Diamond Head, Hawaii thirty-six hours ahead of the fleet after the 2,500-mile race.
The exact date of this design work of a 60-foot catamaran by Ben Lexcen (Bob Miller) is unknown, as no date, or clients name is shown, but other sketches indicate it was during the early 1970’s when he was still in the ‘Miller & Whitworth’ partnership. He had sailed mono hull racing yachts, several times in Hawaii and was aware of the modern CSK Catamarans. As an ever-innovative yacht designer, he would have been drawn to design his own version, which this work appears to verify. The Ben Lexcen (formally Bob Miller) design for the 60-foot racing catamaran could well have been inspired, or based on the 58-foot SEASMOKE.SignificanceBen Lexcen (formally Bob Miller) was generally known for designing fast monohull ocean racing yachts, International 12mR America Cup yachts, dinghies and racing skiffs. He designed and built a 13-foot sailing catamaran while still a teenager, but did not appear to venture into multihull design, other than this 60-foot yacht. The interest in modern sailing catamarans developed in the 1960’s and a number of prominent yacht builders produced them. With a constant interest in fast sailing yachts, it would be been natural for Ben Lexcen to venture into multi-hull craft.
