Jim poses on the foredeck of the former US Navy dive support ship USS Clamp (ARS-33), a much decorated veteran of World War II and a diver support and salvage vessel used in the atomic bomb tests at Bikini Atoll in 1946. In 1989 and 1990, Jim dived the sunken fleet at Bikini with the National Park Service's Submerged Cultural Resources Unit. They were the first divers to reach some of the wrecks since Navy hardhat divers from Clamp had visited them in 1946. In 2005, while touring the "Mothball Fleet" at Benicia, California, Jim recognized Clamp and asked permission to visit the ship.
