Istria was a 15-metre class racing yacht designed by Charles Ernest Nicholson and built at the Camper & Nicholsons yard in Gosport, Hampshire, in 1912. She was the first yacht in the world with a lightweight, laminated wood construction and the first to feature a marconi topmast.
She was designed by Charles Ernest Nicholson and built for Charles C. Allom in 1912. In her first season she won twenty-nine out of thirty-one starts in European waters. It was intended that the boat competed as a challenger for the 1914 America's Cup. During the trials, World War I started and the next competition was the 1920 America's Cup.
