James Wharram (15 May 1928 – 14 December 2021) was a British multihull pioneer and designer of catamarans.

Polynesian beginnings

edit

Wharram was born in Manchester, England. In 1953, after long studies into the records of boats of the Pacific in the libraries and museums of Britain, and inspired by Eric de Bisschop's book The voyage of the Kaimiloa,[1] he designed and built the first British ocean-going double-canoe-catamaran, the Tangaroa (length 23 feet 6 inches (7.16 m)) and in 1955–56 sailed with Jutta Schultze-Rhonhof and Ruth Merseburger,[2][3] across the Atlantic to Trinidad – the beginning of cruising and transatlantic crossing with a catamaran.[4][5]

No scholars in the Western world at this time believed that the Polynesians had boats capable of directed ocean voyages. Wharram believed otherwise and set out to prove it by doing it himself. He followed this first Atlantic crossing by building a 40-foot V-hull double canoe, Rongo, in Trinidad in 1957–58, with Bernard Moitessier's help, and sailing her across the North Atlantic in 1959 from New York to Ireland.[6] This was the first west-to-east crossing of the Atlantic by catamaran or multihull.

The story was told by Wharram in the 1969 book Two Girls Two Catamarans.[7]

From 1973 Wharram was assisted by his co-designer Hanneke Boon.[8] In 1987-92 James and his partners built a new flagship, the 63-foot catamaran Spirit of Gaia, which they sailed into the Pacific and round the world, to study Indo-Pacific canoe-craft (1994–98).

The Lapita Voyage

edit

In 2008–09 James Wharram and Hanneke Boon conceived the Lapita Voyage expedition, sailing two double canoes based on traditional Polynesian hullform and crab claw sails, from the Philippines to Tikopia and Anuta in the Solomon Islands. The ‘Lapita Voyage’[9] was a major expedition in Experimental Marine Archaeology. It was the first exploration of one possible migration route into the Central Pacific by Ethnic sailing craft.[citation needed]

Wharram catamaran designs

edit

Wharram designs are inspired by Polynesian double canoes and typically have an open deck, with small deckpod(s) for crew shelter. Wharram combined boat building with studies of Polynesian culture. Most modern catamarans are built as a single rigid structure thereby sustaining greater forces and stresses in waves, whereas on Wharrams the separate hulls are connected to the crossbeams with (synthetic) rope lashings, in true Polynesian style. The flexibility of the Wharram system makes the boats suffer less stress in ocean waves.[10]

Wharram's designs covered a range of sizes from the 14 feet (4.3 m) Hitia to the 63 feet (19 m) Pahi 63 Gaia.[11]

The rig on Wharrams since the early 1980s is the 'Wharram Wingsail Rig',[12] an appropriate tech squareheaded rig with low turbulence pocket round the mast and a short adjustable gaff at the head. The advantages of this rig are simplicity, low turbulence and the fact that it can be lowered in a following wind at any time. The Centre of effort on all Wharram rigs is kept low, giving them very good stability. No full-size Wharram has been known to have capsized.[13]

Many of the cabin interiors are designed to flexy-space principles, the concept being multi-purpose space on a human scale, in which less is more and the simpler the construction, the better. The slim v-shaped hulls have a very good speed/length ratio and all have canoe sterns, giving minimum drag, even when loaded. This hullshape requires no keels or boards to sail to windward, giving hulls with little draft and easy beachability. Wharram also keeps freeboards low for minimum windage.[14]

Personal life and death

edit

Wharram died on 14 December 2021, at the age of 93.[15]
