PENZANCE was a sloop, one of a series built between 1928 and 1932. She was built at Devonport Dockyard.

She was lost on 24 August - under the command of Commander Allan John Wavish she sailed from Sydney, Cape Breton, Canada on 15 August as escort to slow convoy SC.1, composed of 42 ships, bound for Liverpool. Speed should have been 7.5 knots, but very poor weather reduced this to just 6.5 knots. On 24 August at 17.35 the convoy was in position 56.20N 28.20W, the Penzance was ahead of the convoy zigzagging at 8 knots when a torpedo track was seen on the port side, about 500 yards from the ship. Engines were put to full ahead and the helm put hard over, but before the orders could take effect she was hit on the port side amidships, below the foremast. The explosion blew the ship in two and she broke up and sank rapidly, steadily heeling over to starboard, disappearing in less than a minute. The bow and stern rose clear of the water before sinking. Two of the convoy, the Blairmore and Fylingdale lowered boats to pick up survivors. Her attacker had been the U.37 (Oehrn).
