While most of the wood has long since disintegrated from what is believed to be an early to mid-19th century wooden-hulled shipwreck on the deep Gulf of Mexico seafloor, copper that sheathed the hull beneath the waterline as a protection against marine-boring organisms remains, leaving a copper shell retaining the form of the ship. The copper has turned green due to oxidation and chemical processes over more than a century on the seafloor. Oxidized copper sheathing and possible draft marks are visible on the bow of the ship.
