The website of a Derek Kelsall trimaran and the story of the development of modern multihulls

Tehini

The 51 foot Tehini built in Wales in 1968 was Wharram's dream ship intended to sail around the World via Cape Horn. He crossed the Atlantic twice in her 1973/74 and she made two more crossings with other skippers. Many other boats have been built to the Tehini plans too. Only 40 feet on the waterline she is a very small boat for her length like most of the Wharram designs and although the hulls each have a centre cabin that is about 10 feet long they have the same basic layout of the classic designs Oro, and Narai with a large quarter berth fore and aft of the main cabin in each hull. The last section of the hulls is either a toilet, storage or a berth. I cannot imagine that the two forward berths were very comfortable at sea! Some builders of all three designs put a toilet/shower in the middle of the chartroom area with separate hatches into each berth which then had its own "dressing room" area in the cabin section. Others converted a berth into a toilet/shower cabin or a seat and table. Adding a covered cockpit on the slatted deck was popular too. Similar developments are then seen in the much improved Tiki 38 and Tiki 46. Looking at the pictures of Tehini I am left counting the number of people on board and wondering where they all went down below!!

But in my view Tehini was a magnificent creation and James was rightly proud of her. But after building Spirit of Gaia he was obviously out of love with Tehini and apparently she lay looking like an abandoned wreck at the bottom of his garden before he burned her. A sad end.
