I dreamed up this design in 2000. Hence the designation…F2K.

The design is a blend of my Fish Hybrid and the longer style “fins forward” round pin kneeboards I had been enjoying since 1990. These boards are designed a little longer than the Blast Fish hybrid. The extra length helps with catching waves. The 4 fin cluster is placed further up from the tail. This makes it ride like a shorter board. Other notable differences are;

Increased overall width, rocker, and a redistribution of foam volume.
In effect, the boards are foiled out thinner at the sides and ends.
This creates a board with increased overall torsion flex. The lively flex enhances acceleration yet dampens any vibrant board chatter caused by wave surface turbulence. The ride is smooth, fluid.

This is a super versatile board.
They can be tuned to be used in small surf of a California type beach break as well as large powerful Hawaiian style waves.

Incredibly fast and highly maneuverable they are the core of our quivers.
