From BSAC (might be worth considering...)
"DIVE magazine is pleased to announce the launch of a series of events beginning in 2009 with the DIVE Fest - Party on the Beach, which takes place 15th to the 17th May 2009 at Pentewan Sands in Cornwall, with the support of BSAC. At this
festival of diving, visitors will be able to go diving either with their own clubs and branches or through an on-site provider, they will also be able to view and try out new kit, attend seminars and hear speakers, but most of all get together with other divers for a weekend of partying and diving. The weekend's highlight will be a beachside party with a band, bonfire and hog roast. DIVE and BSAC will be releasing ticketing information within the next few weeks, but please support what is going to be a fantastic diving event and put these dates in your diaries now."
