Kelly Slater designed the K2.1 to be more maneuverable and faster off the top then the original K fin. The side and center fins have different templates, foils and flex patterns. The larger, more upright side fins have greater flex for tighter and faster turns. The smaller, stiffer center fin adds control. Side: Base- 4 3/8" 110 mm. Depth- 4 1/2" 115 mm Center: Base- 4 1/4" 107mm Depth- 4 3/8" 111mm
