Underwater directions: The north of the Island is best for diving but it is easy to get lost in all the gullies here. The is plenty to see and because of the shallow depth, you will get long dives. There is a wreck called The Gothenburg City which lies to the north but you will only see bits of rusted metal, nothing recognisable as a wreck can be found. The Janet Clark which lies to the northeast of the island in 9m with the bows which are smashed to the island and the prop and boiler a little further out. some ribs are still standing up from the seabed.

Air & Nitrox:  Deep blue

Site Hazards:  Low viz after bad weather. The causeway has taken lives when people try to cross it at High tide and get swept off or just walk off.

Other comments: St. Mary's Island is a voluntary marine reserve so take only Photos. For best diving conditions you need about five days of low south-west winds. There are a few shipwrecks here including the Lovely Nelly, Gothenburg City, California, Janet Clark and the Confidence.
