Setting this self-designed Twin Fin / Trailer combination apart from others in Kelly’s history is optionality - the two twin fins come packaged with two separate trailer options; the larger ‘Stabilizer’ trailer enables more drive and hold while the smaller ‘Guitar Pick’ trailer creates a freer experience, with less directional drive and more slide, second only to the uninhibited lateral freedom of surfing the Twin + 2 as a pure Twin Fin. Each trailer option can also be used together with any other fin set, for example the Stabilizer or Guitar Pick can be used in the thruster box of the KS1 Quad set. Regarding the Twin + 2 template shape and size, Kelly says he believes in “The smaller the wave, the larger the fin theory” describing the way that small wave surfing benefits from larger fins with high surface area, but as a fin designer, he’s also mindful of all-around performance, continuing that: “I wanted something that would also handle higher speed waves. This template provides me the best of both worlds, being enough in a small, flat wave (especially with the hybrid thruster trailing fin options) and not too much fin at higher speeds.”FIN DIMENSIONS :TWIN FINAREA | 13500 MM SQUAREDBASE | 130 MMHEIGHT | 137 MMREAR STABILIZER FINAREA | 4980 MM SQUAREDBASE | 99 MM HEIGHT | 75 MMREAR GUITAR PICK FINAREA | 2840 MM SQUAREDBASE | 98 MM HEIGHT | 45 MM
