Channel Islands Black Flag Whip Surfboard Model Description: The Channel Islands Black Flag Whip Surfboard is Kelly’s 2010 small wave design. The same shorter, wider Whip outline with Al’s single to double Tri Plane Hull bottom. Kelly finds the board is fast and has an even more responsive feel than the previous single concave version of the Whip. A double concave deck gets your feet closer to the water line. We have also added carbon fiber strips on the bottom stretching from the nose to the leading fins. Stopping the carbon fiber near the leading fins concentrates the flex in the tail, thus providing more spring out of turns. The half moon tail option gives the board more release out of the top of the wave.Experience: Everyday use by intermediate to expert surfers.Ideal Wave Size: Knee to head high surf.
