"His Majesty's Yacht Britannia was a racing yacht built in 1893 for RYS Commodore Albert Edward, Prince of Wales. She served both himself and his son King George V, with a long racing career." ---
"Despite a lull in big yacht racing when the new linear rating rule came into effect in 1897, Britannia served as a trial horse for Sir Thomas Lipton's first America's Cup challenger Shamrock, and later passed on to several owners in a cruising trim with raised bulwarks. In 1920,[1] King George V triggered the revival of the "Big class" by announcing that he would refit Britannia for racing. Although Britannia was the oldest yacht in the circuit, regular updates to her rig kept her a most successful racer throughout the 1920s. In 1931, she was converted to the J class with a bermuda rig, but despite the modifications, her performance to windward declined dramatically. Her last race was at Cowes in 1935. During her racing career she had won 231 races and took another 129 flags." (Wikipedia)

The racing yacht Lulworth was built in Southampton in 1920:

"The boat's name comes from Lulworth Castle, which belonged to her second owner, Herbert Weld, whose grandfather was a charter-member of the Royal Yacht Squadron.[1] The Lulworth (1920) was built by the White Brothers' Yard for Richard H. Lee, who wanted a racing boat to compete in the premier yachting league in Europe: the British "Big Class".Shortages in the supply of premium spruce after World War I meant that Lulworth's original lower-mast was made of steel instead of wood. This constraint handicapped Lulworth greatly, leaving her trailing older, more famous Big Class racers like Thomas Benjamin Frederick Davis's Herreshoff-designed schooner Westward (1910), HMY Britannia I (1893) and Sir Thomas J. Lipton's Fife-designed 23mR Shamrock (1908).Her gaff-rigged sail plan was updated several times to no avail, until America's Cup naval architect Charles Ernest Nicholson redesigned the rig with a wooden lower-mast and adjusted the keel balance. By 1924, Lulworth's flaws were corrected and she became an accomplished racer in all subsequent seasons of the Big Class: from 1920 to 1930, she took part in 258 regattas, taking 59 first places, 47 of which were after 1924."
