Hand Deeps is an area of the English Channel located 8 nautical miles south-west of Rame Head, Cornwall and 3.5 nautical miles north-west of the Eddystone. The name comes from the five pinnacles there which rise from the surrounding sea bed depth of 55 metres to depth between 7 and 19 metres from the surface. The pinnacles are within a rectangle about 1 nautical mile north-south and 0.5 nautical miles west-east.
