HMCS Sans Peur was a notable armed yacht that served with the Royal Canadian Navy during World War II. Originally constructed in 1933 by John I. Thornycroft & Company at their Woolston, Southampton yard, it was initially named Trenora. The vessel was built for Ernest G. Stanley, a nephew of Rudyard Kipling, and launched on 11 May 1933. It measured approximately 210 feet (64.0 meters) in length, with a beam of 30 feet (9.1 meters) and a draught of 13 feet (4.0 meters), and had a gross register tonnage of 856 GRT. Powered by twin Polar Atlas diesel engines, it cruised at about 12.5 knots, with a top speed of 16 knots, covering 7,000 nautical miles on a single tank. In the 1930s, the yacht was sold to George Sutherland-Leveson-Gower, 5th Duke of Sutherland, who renamed it Sans Peur, meaning "Fearless" in French. The vessel was used for leisure, including visits to British Columbia and a world cruise. During a 1939 cruise off California, Sans Peur grounded on a sandbank near Espiritu Santo Island, resulting in hull damage but was refloated and repaired with the help of a tugboat. Requisitioned by the Royal Navy in October 1939 and transferred to the Royal Canadian Navy, Sans Peur was modified for wartime service. It was equipped with naval guns, including a 4-inch gun from a former destroyer, a 12-pounder, and 25 depth charges, along with radar installed in 1941. The vessel was the first Canadian armed yacht to be commissioned, entering service on 3 March 1940. Initially tasked with anti-submarine patrols and training along the British Columbia coast, Sans Peur played a significant role in defending the west coast, including tracking Japanese submarines after the attack on Pearl Harbor, and transporting prisoners of war. In 1944, Sans Peur was transferred east to Nova Scotia for anti-submarine training at HMCS Cornwallis, where it operated alongside submarines and participated in escort duties. After the war, it continued as a training vessel until January 1947, when it was paid off and sold. The vessel changed hands multiple times, reverting to the name Trenora, and was used as a private yacht in the Mediterranean. It was further sold to Japanese buyers in 1972, renamed Sans Peur again, and served as VIP accommodations during the 1975 Ocean Olympics at Okinawa. Its ultimate fate remains unknown. Throughout its service, Sans Peur exemplified the adaptability and versatility of yachts converted for wartime purposes, contributing significantly to Canada's naval efforts during WWII and maintaining a distinguished maritime legacy.
