Later that year, Captain was put into harbour service. On 22 March 1813, she was accidentally burned in the Hamoaze, off Plymouth, Devon. At the time, she was undergoing conversion to a sheer hulk. When it was clear that the fire, which had begun in the forecastle, had taken hold, her securing lines were cut and she was towed a safe distance away from the other vessels so that she could burn herself out. Even so, orders were given that she be sunk. Ships' launches with carronades then commenced a one-hour bombardment. She finally foundered after having burned down to the waterline. Two men died in the accident. The wreck was raised in July and broken up at Plymouth.
