Naval Air Command Sub Aqua Club

The Naval Air Command Sub Aqua Club (NACSAC) was an organization within the Royal Navy that oversaw sports, technical diving training activities for naval aviation, and fleet units. Today, it has branches at RNAS Culdrose (HMS Seahawk), and RNAS Yeovilton (HMS Heron). Both bases provide training, and club members regularly dive in their local areas on weekends. Diving instruction, from beginner to advanced level, is offered under the auspices of the British Sub-Aqua Club.Information on the NACSAC on the UK Ministry of Defence website.
/ref> In 2005, NAC-SAC was closed down as an organization in favour of a Royal Navy Sub Aqua Club, which is what Lieut. Graham and CPO Larn had wanted from the outset of NAC-SAC, which was only given that title since HMS Vernon, the RN Diving School at Portsmouth, would not support the idea of sport diving within the service.

History

In the early 1960s, a group of chief petty officers from the Naval Air Command formed amateur diving clubs and mounted annual expeditions.Interview with Roy Graham in December 2005.
In retirement, he and his wife Grace moved to the Isles of Scilly where they ran a holiday guest house and became active in developing tourism on the Isles. He died on 16 March 2007, shortly before the 300th anniversary of the great naval disaster of 1707, and was buried in the churchyard of St Mary's Old Church, St Mary's. These clubs were first based at the naval air stations of Portland (HMS Osprey), Culdrose, and Yeovilton and conducted diving under the auspices of an umbrella organization which became known as the "Naval Air Command Sub Aqua Club" (NACSAC). The club's first chairman was Lieutenant Roy Graham (1924–2007), an engineer officer who had begun his diving career aboard the aircraft carrier . Whilst in Gibraltar, he was in charge of diving training on this ship. Following a shallow water diving course with 24 entrants and only himself and a Royal Air Force medical officer finishing the rigorous training, Graham became the only Fleet Air Arm officer with a naval diving qualification.

Chief Petty Office Richard Larn was the organization's Diving Officer from its formation in 1960, who, apart from a period on HMS Bulwark in 1967-68, continued to organize training and expeditions until his retirement from the navy in 1971. One of the club's first projects was to send a team of divers to the Isles of Scilly to find an historic Royal Navy ship, HMS Association, a 90-gun ship of the line lost in the great naval disaster in 1707.''Wreck of the fleet and treasures of the deep'', The Islander 3, Autumn/Winter 2007.

Their initial dives began a series of navy visits that continued for four years. In 1964, 1965 and 1966 the
divers could only access the Western Rocks, but barely around the Gilstone Ledge, where a later expedition managed to locate the wreck of in 1967.''BSAC Pioneers'' on the British Sub-Aqua Club website.

The annual expeditions, organization to promote diving as an exciting sport, have become a key focus of NAC-SAC activities. Despite changes to the Royal Navy Fleet command structure, NAC-SAC flourished and at one time had branches in seven Fleet Arm Arm bases until superseded by the Royal Navy Sub Aqua Club.
