SHAMROCK V: DATA TABLE & LINES

Category: SHAMROCK V

02942VFirst J-Class yacht to be commissioned and built in the UK

Sources : http://www.boat-duesseldorf.com Towards the end of 1929, Lipton issued his fifth and final challenge for the Cup (he was busy planning his sixth when he died). In the negotiations that followed as they always do when someone lays a challenge, Lipton agreed to build his yacht to the American Universal Rule, and that the yacht would be of the J Class.

For the design and building of Shamrock V Lipton went to Camper and Nicholson's. Shamrock V was the first of his yachts to be built to Lloyd's A1 scantling requirements, this stipulation having been agreed between the Americans and the British earlier to avoid the construction of lightweight hulls which in the past had proven unseaworthy and expensive.

Teak and elm

Of semicomposite construction, Shamrock V had her stem, stern post and counter timbers of teak and her wooden keel of English elm. Her lead keel weighed 78 tons. Her frames were entirely of steel with a longitudinal ‘trough' of steel plates. The planking was mahogany and the main deck was laid with yellow pine. The mast, pear-shaped in sections was not less than 162 feet from truck to heel and was constructed of about 50 pieces of silver spruce. Shamrock V contrasted strongly with the other British Bermudan rigged yachts because although she carried some 700 sq ft less sail area, her sail plan was 152 feet high compared with the 137 feet of the others.
