Fort Foster

The Wandby is a British freighter built in 1899 that has almost all vanished from when she founded on rocks in 1921. A few small pieces of the wreck can be found in about 20ft of water- a boiler at most 15x15ft in size are still visible, a small cylinder divers have also reported small portions of the hull located nearby as well. 

Note this dive should be done at high tide and divers will only get one dive in.
