This unidentified wreck out of Kimmeridge was discovered in 1990. Divers have named it the "pin wreck" due to the large pins holding the copper hull to the wooden frame.
The anchor standing upright to one end is of a mid 1800s design, so the wreck is thought to be post-1850.
The wreck itself is upright on a sandy seabed at 30m, which gives pretty good visibility. She is a very interesting wreck, yet very confusing. A set of machinery midships - a vertical capstan and associated cogs and worm gears plus a steam boiler and water tanks - but no sign of propulsion. This has suggested some sort of work barge, which along with stories of a recovered military button and single diving boot have further confused wreck identification.
