|James Wharram designed his first offshore cruising catamaran, the 23' 6" TANGAROA in 1953, before the word catamaran was yet in common use and began sailing with her off the coast of Britain with two German girls, Ruth Merseburger (Wharram) and Jutta Schultze-Rohnhof. He was inspired to do this by Frenchman Eric de Bisschop, who sailed a double canoe from Hawaii to France in 1939. James believed in the innate seagoing qualities of the double canoe and set out to prove them with two pioneering Trans Atlantic voyages on TANGAROA (1956) and 40ft RONGO (1959). (see his book: Two Girls Two Catamarans)
Since then, James Wharram, has been designing, building and sailing offshore catamarans longer than any other multihull designer. Already in 1987 the "Multihulls Buyers Guide" showed that James Wharram had sold three times more plans than any other multihull designer in the world. Design sales have since topped 10,000.
One reason for this success is that James Wharram is a "hands-on" designer having, over his lifetime, built personally many of the prototype designs. These prototypes were built in the open, in barns, workshops and all the range of building sites available to self-builders, in a variety of climate types from northern European to the Tropics.
