10mm concave full length of the board , starting out between the rolled shoulders in the nose. This is to split the width of the nose when doing a full rail turn. The rolled shoulders still give lift and it is like two hulls really. Something I have been playing with.
This flows through to a fill width 10mm concave in the middle of the board to capture all the flow and give lift with a hard rail edge.
The flow is then funneled in between the fin set out through the tail.
The fins also sit on a chine that releases the flow from the fins and narrows the tail width.
A 5 fin setup to experiment with
Ready to be glassed
It is thin @ 2" thick but 34. 5lt volume. Thin rails for higher performance.
