If you've wondered about surfboards and the differences between them, this is the place to get your questions answered. Christie is a surfboard shaper, Holly is a former pro surfer. The two know a lot about surfboards. They pull out some selections from the SWA quiver and break down the differences between a traditional log and high performance longboard, what defines a midlength, what is a fish, the differences between high performance shortboards, volume, fin sizing and placement, rail shape, and everything in between.
