Pednathise Head is the southern most area of Western Rocks, a group of the Isles of Scilly, southwest of Cornwall. In 1912 at the start of winter, the 2600 ton Greek steamship Antonios came to grief just off Pednathise Head. This diving site sets the scene for a great, pleasing dive, not just for the wreckage but the surrounding rocks. Dropping down the shot, a small insignificant gully is passed through and at first around 17m it doesn't seem there is much to see. But at this depth immediately on the left of the shot line a rock looks rather rounded in appearance. On closer inspection it is revealed to be a large boiler with its casing broken in places, where steam pipes can be seen - easily missed!
With the possibility of conger the shot line deepens to 20m with yet another boiler on the seabed amongst much hull plating, undistinguishable items of wreckage and winches. Dropping to 22m this extends some 30m as a wreckage area where many crabs, starfish and cotton spinners inhabit. Bottoming out at 26m directly in front and hard to miss is a deeply cut gully, some 3m across at its base. To the left hand side is a sheer vertical mass of rock extending almost to the surface, to the right a ridge some 4m high. Dives can go off in differing directions after finishing with the wreckage. Dense clusters of red dead man's fingers, along with gardens of nermetesia or sea beard, hydroids and nudibranchs can be enjoyed along the dive.
