Here is my Larry Bertelman designed 'Anything is possible' 6'0" twin fin. Its very flat, with hardly any rocker and long straight rails with no flys going down to a wide swallow tail. It has the famous 'Pepsi' spray and a pair of vee's cut into the tail which are unique to Larry's designs.
Larry - The Rubberman opened the door to the modern surf age. Arriving on the surfing scene amid a period of flux in surfing styles around 75 to 78, he demonstrated that no limits exist beyond our imagination. He didn't invent the short board; he just showed us how to ride it. No one had a greater influence on the way people surf today -- from the best in the world on down -- than Larry Bertlemann. From the time he was a cheeky grom Bertlemann was interested in design. Collaborating with Town and Country, George Downing and Hawaiian Pro Designs to become a driving force in creating the swallowtail.
