Twin Fin Surfboards have been around much longer than you think. Dating back as far as mid to late 1940's with Bob Simmons' experimentations into planning hulls and utilizing parallel twin keels to help trim along the face of a wave with more projection and control instead of controlled drag. Since then, the twin fin has gone through many variations making their biggest impact in the late 70's when Australian Surfing Icon Mark Richards, also known as "MR", started dominating professional surfing with his re-invented twin fin design. From 1977 to 1981 Twin Fins were the pinnacle of performance surfing design.
