The Channeled Twin Pin has emerged as the alternative step-up of choice over the last few years as video of Torren Martyn riding Morning of the Earth Surfboards has demonstrated the amazing capabilities of this type of design in heavy waves worldwide. Inspired by this footage, as well as by the unique channeled designs of Dave Parmenter, I blended a few of my favorite templates together to create a wide-point forward shape that is intended to surf when the waves are pumping. This board marries the loose and free feeling of twin fins with the drive and hold of a pintail step-up. The channels add bite, control, and thrust that allow this board to be ridden with authority in larger surf, and the thicker foil gives tons of paddle power for chasing down those outside peaks. I prefer an upright style twin fin, such as the TA Twin, for the best balance of drive and maneuverability.
