DaFiN was developed by Andy Cochran, an Aussie who has made Hawaii his home since the 1970s. Cochran was a lifeguard at Australia’s famous Bondi Beach and was one of Oz’s early surfing pioneers. In the mid-1990’s, he created the initial design for DaFiN out of a wooden block. Fins were produced in Australia and then put to the test in Hawaiʻi with world renowned Hawaiian watermen Mark Cunningham and Brian Keaulana.
