The Swish surfboard has a wider outline than a standard shortboard. This model works very well in smaller, mushier surf and can be used as a good contest board for those typical, smaller contest conditions. The Swish loves to be ridden in summer surf or any day that lacks any power. The flatter overall rocker and wide tail, give you the speed through the flat spots, while your narrower board tends to bog down. The single wing swallow is wide at the 12" mark for drive, then pulls in for good holding power in hollower sections of the wave. The bottom comes with a single concave, blending into a double concave with "V" toward the tail. It can be ordered as a 5 fin, which can be surfed as a tri fin or a quad.
