The late 70s very early 80s was when what we think of as pro Surfing came of age. There was a pro Surfing scean in the early 60s but it was tiny and relegated mostly to coastal areas. In the late 70s bigger money got involved and it became a little more mainstream also the equipment was changing. The twin fins and tri fin thrusters where putting surfers on different places on the wave and allowing for more radical maneuvers.Sorry I did not follow the names. And back then actually didn’t know there was such a thing as world famous surfers.
