. Shamrock V was built wood, with mahogany planking over steel frames and, most significantly, a hollow spruce mast. Following its launch on the 14th April 1930 it showed early promise on the British Regatta circuit winning 15 of 22 races. It also underwent continuous upgrading with changes to its hull shape, rudder and modifications to the rig to create a more effective racing sail plan, before departing to America in time for the 14th 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 Classes immense power and beauty, their Achilles heel would be the exorbitant cost to construct and race them. Winthrop Aldrick’s syndicates, Enterprise, emerged from the competitive round robins as the eventual defender.

Enterprise was the smallest J Class to be built, its 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 its Park Avenue Boom, hidden lightweight winches and the world’s first duralumin

The first of the best of seven races was a convincing victory for Enterprise winning by nearly three minutes. Shamrock V was to fair worse in the second race loosing by nearly 10 minutes. The third race finally provided the ensembled thousands on the shore at Newport with the racing they had craved for. Shamrock V’s initial lead at the start was relinquished to Enterprise after a tacking duel. Following this surrender disaster struck, as Shamrock’s main halyard

 parted and her sail collapsed to the deck. The forth 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 Venderbilt. For Sir Thomas Lipton, after endearing himself to the American public during 31 years and five attempts he 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 1932 as a trails horse to gain experience of J class racing. He would also add to Nicholson’s skills with his own aeronautical expertise and material knowledge to build and perfect his challenger for the 13th America’s cup, Endeavour

Shamrock V was then sold to Sopwith’s aviation friend, and fellow yachtsman, Sir Richard Fairey of Fairey Aviation

 and Yankee) during the 1935 regatta season. In 1937 Shamrock was sold to the Italian senator and industrialist Mario Crespi. This change in ownership prompted Shamrock’s only change in name. 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 not for performance, but for comfort by installing its maple interior.

A renaissance for Shamrock V began in 1962 with its acquisition by the Italian yachtsman Peior Scanu. He instigated a comprehensive three year overhaul commencing in 1967 with Shamrock V returning to the Camper and Nicholsons
