Shamrock V was built in 1930 for Sir Thomas Lipton’s fifth and last America’s Cup challenge. Designed by Nicholson, she was the first British yacht to be built to the new J Class Rule and is the only remaining J to have been built in wood. After launch she was continually upgraded with changes to hull shape and rudder. The rig was also modified to create the most effective racing sail plan but she was no match for the faster US design “Enterprise”.

America which was modeled on the state-of-the-art pilot ships of New York astonished people from the moment she arrived in Europe. Her reversed bow, like a Clipper-ship, her tin plating, and her sails of vertical layers of cotton, laced to the masts, had never been seen before.
