Jim Abernethy’s Scuba Adventures (JASA), based in South Florida, innovated and set the bar for diving with large predatory sharks without a diver cage. For over 35 years JASA has been the premier outfitter for up close and personal encounters, in addition to world-class photography opportunities, with tiger, great hammerhead, oceanic white tip, bull, lemon and whale sharks. He is best known as a passionate crusader for shark protection. For decades Jim Abernethy’s Scuba Adventures, Inc. has conducted top rate charters and expeditions in south Florida, Mexico and the Bahamas. In 1999, JASA added a 10-passenger live-aboard vessel (M/V Shear Water) and has since been the leader in photography/video expeditions with a mission of interacting with some of the world’s largest predatory sharks.
