Spark Plug

The Spark Plug is my latest refinement in a 'modern' performance twin fin. Moderate nose lift with a lower tail rocker and a bit of vee off the tail. Slight concave through the center with a bit of double concave in the fin area.  Fins are set back a bit to give more speed, hold, and control. The rail is tapered out in the fin area allowing the rail to knife in the face. Outline has a nice nose area for paddling and planing, and between the feet the curve is straightened out for more speed and hold.
