SHAMROCK 23-METRE : DATA TABLE & LINES

Category: SHAMROCK 23M

Shamrock23MFTV.jpg“Shamrock” was designed by William Fife (III) in 1908 as a potential challenger for the America’s Cup. The Americans refused the challenge but Lipton asked Fife to continue building at shipyard of William Denny & Brothers in Dumbarton..
Shamrock was built under the “International Rule” used in England and the other European yachting countries while the United States adopted the “Universal Rule”

The New ShamrockSir Thomas
Lipton's new racing yacht Shamrock has been successfully launched and is now being fitted out in the Solent for the season's competitions. She is longer than last year's champion, White Heather, and is a good deal fuller in the midship section class. More striking, still, however, is the manner in which the lines of the yacht are stretched out. Instead of the comparatively short, rounded ends of White Heather a development which was probably caused by the operation of the new rule of rating Shamrock is drawn out in long, graceful overhangs.

The modeling of the counter is particularly handsome. The beam is carried aft well into the counter, and, as this is balanced with good and fairly full shoulders, it is apparent that this vessel will have at least one of the elements which helped Reliance to success -i. e., a long sailing side when hard driven, although it goes practically untaxed in the measurement.
The free board looks more than was expected, but the unfamiliar appearance of the green top sides with the white boot top under may make this something of an optical delusion. At all events, there is no bulwark to increase the height of topside, the only foothold for the crew being a light rail set well in on the deck. From the outward appearance, the yacht is in all respects a racer of the thoroughbred type, and should give a good account of herself when pitted against other vessels in the big class.

From Fast and Bonnie: History of William Fife and Son, Yachtbuilders:

Book1.jpgLipton then discussed this with Fife, who refused to design to the old condition. As a result Sir Thomas commissioned Fife to design and build a composite 23-metre whose frames would be prepared by Denny at Dumbarton. The boat would differ little from the design with which Sir Thomas had intended to challenge for the cup and was launched in April with little or no ceremony. Her owner was not present and she was called Shamrock.

She was a large yacht and had to be launched with the new floating dock. The interior finish, as for all the Fairlie-built yachts, was superior. The saloon was panelled in rare hardwoods and tapestry, and electric lighting was installed for the first time in a Clyde-built yacht.
She had accommodation for 22 crew.

Book2.jpgImage20.jpgShamrock {23-metre) (1908), cutter, 94.02 tons TM, 96.6 ft OA, 20.85 ft beam. Designed and built by William Fife & Son, Fairlie for Sir Thomas Lipton. She carried 9,843 sq.ft. of sail. She sailed across the Atlantic, arriving in New York on 7 June I920. She acted as the trial horse for Shamrock IV.

She was skippered by Tom's brother Alf, along with Tom, three other brothers and two of alf's sons. So out of a total crew of 22, seven were Diapers.
