DELTA-V - Mandala Custom Shapes

The addition of channels to add functional edge and control is nothing new, and here we’ve added them to our tried and true spiral vee concave to produce our own “Delta-V” bottom contour. Micro-channels located behind the trailing edge of each fin creates an area of low pressure, decreasing the turbulence at the trailing edge while adding a touch of rocker at the rail. Deep twin channels provide extra edge and direct water flow off the tail, stabilizing the looseness of the twin fin set-up in larger surf without the drag of a trailing fin.
