The broken remains of the Victorian steamship Mohegan are probably the best-known and most intensively dived wreck on the Manacles reef off the Lizard. The liner hit the rocks in 1898, and divers now follow her flattened hull, engine and three huge boilers on a ten-minute boat trip from Porthkerris.

Also known as SS Mohegan, The Mohegan.

The dive

The dive is timed for slack water, which falls between 2 hours and 1 hour before low and high water at Coverack. Divers reach the wreck about halfway between the boilers and the stern at 22 m, a little more at high water, and most of it lies between 22 and 26 m. The hull is well broken and heavily salvaged, but its girders give a rough grid to follow, the engine stands above the wreckage and the three huge boilers lie forward of it.

A dive can also start at the outer pinnacle of Maen Voes, following a wall crusted with anemones and hydroids down to the rocky seabed at 14 m, then swimming north-east for a few minutes to the hull. The way back climbs the reef past gullies plastered with anemones, with nudibranchs and most of the UK's wrasse on the rocks.

Season follows Cornwall: Wrecks and reefs are dived all year when the weather allows; mid-May to September brings the sharks.

Know before you go

  • Tides can be a problem away from slack water; on a good neap the wreck can be dived through the flood tide.
