Hi Greg. Search "Port Hunter/ Hedge Fence Shoals ". It’s a WW1 cargo ship that went down in 1918 on the shoals between Falmouth and the Vineyard. It was in a collision with another ship, the captain managed to run it up on the edge of the shoal. If I recall its in the 40-80’ depth range. Visibility not bad, definitely a slack tide dive though. Rests somewhat upright, has large railroad car wheels chained to the deck.
