What are the performance impacts of a hard resin edge at the bottom of a non-hard rail? Below the apex, where the tuck begins. Another way I think about it is not blending the tuck 100% with the bottom and ensuring this corner is preserved with a bead of resin sanded to a hard sharp edge.
I have seen this on fish and some performance shortboards, carried over halfway up the board and then fading out.
Hypothesis is that it creates a faster planing surface when board is flat but its effects when rail is engaged are minimal. Curious to hear anyone’s thoughts.
