Shamrock V was the first British yacht to be built to the new J-Class rule. She was commissioned by Sir Thomas Lipton for his fifth (and ultimately last) America's Cup challenge. Although restored many times she is the only J not to have ever fallen into dereliction.
The services of Charles Ernest Nicholson were once again employed to design the challenger and she was constructed at the Camper and Nicholsons yard in Gosport. Shamrock V was built from wood, with mahogany planking over steel frames and, most significantly, a hollow spruce mast. As a result of rule changes, she was the first British contender for the America's Cup to carry the Bermuda rig. Following her launch on 14 April 1930 she showed early promise on the British Regatta circuit winning 15 of 22 races. She also underwent continuous upgrading with changes to her hull shape, rudder, and modifications to the rig to create a more effective racing sail plan before departing to America in time for the 15th America's Cup.
Four New York syndicates responded to Lipton's challenge each creating a J-Class, Weetamoe, Yankee, Whirlwind, and Enterprise. This was a remarkable response particularly during depression-hit America with each yacht costing at least half a million dollars; and would serve to highlight that despite the J-Class' immense power and beauty, their Achilles heel would be the exorbitant cost to construct and race them. Winthrop Aldrick's syndicate, Enterprise, emerged from the competitive round-robins as the eventual defender.
Enterprise was the smallest J-Class to be built, her size being an early indication of the ruthless efficiency that was employed by the renowned naval architect Starling Burgess. The efficiency of design was coupled to a number of pioneering features such as the Park Avenue Boom, hidden lightweight winches and the world’s first duralumin mast.
The first of the best-of-seven races was a convincing victory for Enterprise winning by nearly three minutes. Shamrock V was to fare worse in the second race losing by nearly 10 minutes. The third race finally provided the assembled thousands on the shore at Newport, the racing they craved. Shamrock V's initial lead at the start was relinquished to Enterprise after a tacking duel. Following this surrender disaster struck, as Shamrock V's main halyard parted and her sail collapsed to the deck. The fourth race clinched the cup for Enterprise after which Sir Thomas Lipton was heard to utter "I can't win".
Shamrock V's challenge was plagued by bad luck and haunted by one of the most ruthless skippers in America's Cup history, Harold Vanderbilt. Sir Thomas Lipton, after endearing himself to the American public during 31 years and five attempts, would die the following year never fulfilling his ambition to win the cup.
Post Cup Career
The British aviation industrialist Sir Thomas Sopwith was to be the next custodian of Shamrock V. Already a keen yachtsman, Sopwith bought her in 1931 as a trial horse to gain J-Class racing experience. He would also add to Nicholson's skills with his own aeronautical expertise and material knowledge to build and perfect his challenger for the 16th America's cup, Endeavour.
Shamrock V was then sold to Sopwith's aviation friend, and fellow yachtsman, Sir Richard Fairey of Fairey Aviation who continued to incorporate aerodynamic and hydrodynamic modifications as well as campaigning her against other J-Class yachts (Velsheda, Endeavour, and Yankee) during the 1935 regatta season. In 1937, Shamrock V was sold to the Italian senator and industrialist Mario Crespi. This change in ownership prompted Shamrock V's only name change. Italian Fascist law had banned the use of foreign names in society, accordingly Shamrock V was renamed Quadrifoglio (cloverleaf). Crespi was also the first owner who modified Shamrock V for comfort by installing her maple interior.
A renaissance for Shamrock V began in 1962 with her acquisition by the Italian yachtsman Piero Scanu. He instigated a comprehensive three year overhaul commencing in 1967 with Shamrock V returning to the Camper and Nicholsons yard. The hull and deck received significant attention along with the modernisation of the systems and engines. The effects of this rebuild were to last the next twenty years during which a remarkable repeat of history was enacted when, in 1986, Shamrock V returned to the ownership of the Lipton Tea Company who donated her to the Museum of Yachting at Newport, Rhode Island. Another extensive restoration was instigated by her new owners and undertaken by Elizabeth Meyer in 1989.
Following changes of ownership in the 1990s and another renovation, Shamrock V participated in a fitting reunion in August 2001 with the only two remaining J-Classes, Endeavour, and Velsheda, for the America's Cup Jubilee in the Solent. In March 2016 it was reported that Shamrock V had changed ownership; she had been listed for sale with an asking price of €6 million.
