James Wharram (born May 15 1928 in Manchester), England is a pioneer in catamaran construction. 1953 he designed the first ocean going Catamaran, the TANGAROA (length 23'6"/ 8 m) which ment the beginning of Cruising (maritime) and Transatlantic crossing with a Catamaran.

An northern transatlantic passage on the RONGO (length 40'/ 12 m) followed in 1959, which he designed and constructed in Trinidad after RONGO was infected by worms. This was the first west to east transatlantic crossing with a catamaran. He shared these adventures with two women, Jutta and Ruth. The supplies consisted of 100 lbs of wheat, 100 lbs of oat, 70 lb block of pressed dates, soya beans, soya flour, lentils, peas, peanut butter, honey and cheese for the 8000 nm long journey. Jutta bore their son Hannes in Trinidad. In 1960 the four started a TV sponsored trip around the world, beeing interrupted by Jutta dying of an inborne illness.^[1] With Hanneke Boon he sailed around the world on the 63 foot SPIRIT OF GAIA from 1995 to 1998. ^[2]

Wharrams are based on polynesian two-trunk boats and typically have an open deck. James Wharram combined boat building with studies of polynesian culture. Wharrams are unique in beeing intelligent boats with beams lashed to the hulls with ropes which absorb the shocks of the waves like elastic bands. Modern catamarans are rigid and put up with greater forces and strain in the waves. Wharrams are built with linen latches or belts, in true polynesian style.* ^[3] The rig is usually a rigsail, which adds safety. No full size wharram has been know to have capsized. ^[4] The cabins and deck space are multifunctional and at human scale. The motto is "Keep it simple!" and "Less is more!" using the little space in a multifunctional modular way. Also the little payload of plywood catamarans keeps it's sailors to the minimum. Usually plywood is used in combination with epoxy for the hull, and laminated beams.

Wharram is not just about selling plans but stands for a philosophy of "Sea People".^[5] As Wharrams are usually home built, Wharram owners (those that actually finish a build and sail off) are known to be determined and caring about their boats. Wharram plans are drawn in a way that anyone can build a reliable transatlantic catamaran. The plans are idiot proof, complete and use "cheap" materials as plywood and epoxy. Due to the safe contruction and professional plans they are much easier to immatriculate than amateure self drawn boats. Wharrams are inexpensive, seaworthy and easy to handle.
