crease structural integrity and provide tactile grip !
Most apparent is the feeling of having your hands grip right into them. It’s snug under your arm, easy to grab and confident when diving deep.
We shape these into the boards with a smooth edge rolling into the channel and a sharper edge closest to the rail. It allows your thumb to slide and lock in. It also increases board strength through rigidity.
The deck channels follow the outline of the board which gives it the same effect as having a “parabolic stringer” setup. It helps to reduce torsional flex.
The deepest part of the deck channel is always at the center and up towards the nose, where you’d typically grab onto it. The foil will taper out above the fin cluster to still allow for tail articulation.
