It's often said that the first artificial diving reef in Europe was HMS Scylla, sunk in Whitsand Bay near Plymouth in 2004. But Scylla was in fact the third ship sunk as an artificial reef; the first was the Glen Strathallan, sunk on this day in Plymouth Sound in 1970.
The Glen Strathallan was a gentleman's steam yacht bought as a 21st birthday present for Robert Colby Cubbin. Cubbin never married and was somewhat of an eccentric recluse; he died unexpectedly in 1951 after sailing on the Glen only 12 times. Cubbin's mother kept the ship exactly as it was when her son died, with his pyjamas neatly folded on the pillow in his cabin, and the door locked. Cubbin’s mother died in May 1955, and in her will she bequeathed the Glen Strathallan to a naval training school, and when she was no longer serviceable, the ship must be taken out to sea and sunk. At the end of her working life, they intended to sink the vessel in the English Channel, but an appeal from Alan Bax at the School for Nautical Archaeology Plymouth (SNAP) changed the plan, and instead the Glen was scuttled in Plymouth Sound on 27th April 1970.
The second ship to be sunk as an artificial reef and for scientific research was the little Trinity House tender Tavy. We sank Tavy in December 1995 next to the Breakwater Fort in Plymouth Sound, and she was used for many experiments over the next 10 years before she broke up.
The Glen Strathallan was the first ship in Britain to be sunk especially for divers as an artificial reef, pre-dating the sinking of HMS Scylla in Whitsand Bay by 34 years.
