Edge Boards - Mandala Custom Shapes

This design came my way via Marc Andreini, who was sent three templates from George Greenough. Marc grew up watching him surf, and cites him as a major influence in his approach to design. Many of the elements George adapted from boat hull design to his kneeboard spoons can be seen in the displacement hulls designed for stand up surfing. Greenough’s many contributions to modern surfboard design and his revolutionary fin templates is well documented, so if you don’t know much about Greenough you should study up about the guy who started the shortboard revolution in the mid-1960s. George sent Marc three templates for these Edge Boards, and has asked Marc to share the templates with certain individuals who he thought were of open mind to appreciate and understand the concept. I gladly accepted and have attempted to study some of the code hidden between the pencil lines. I’ve been able to adapt the concept to some wider templates that work well in the softer waves of Southern California, as well as shaping a few shorter narrower pods for use in hollow surf. The Greenough High Speed fin is a short-based, high-aspect ratio directional stabilizer designed to store and release energy via flex and twist. Short base area allows for quick direct changes and low drag. Moderate area in the tip gives more control through turns initiated off the rail. Hard edge runs from the entry rocker to the tail, and with a smaller fin can almost feel like snowboarding. Fins come in 8.9″, 9.25″, and 9.65″…foiled by Chuck Ames in reliable Volan.
