5`8``x201/2``x2 3/8`` All the fishes have the sort of bottom contour with a low nose rocker leading into a single concave to the front fins to vee from the last 6`` of the board. We have put a double concave through the fin area which helps the change from single to vee. This makes a very fast easy paddling board with speed over flat sections but with the vee off the tail really free`s it up and stops that tracky down the line feeling. A flatter deck with a laid over rail for hold. Fins can be thruster with different size fins, twins, or Quads.
