single vs single to double concaves - 2010/02/10 07:42can someone explain the science behind it? i pretty much understand that singles work better in better waves while single to double works better in all around..or am i wrong?
but a lot of people over at that site are into the design of surfboards & may be able to provide a good answer.

Re:single vs single to double concaves - 2010/02/11 03:53I am no board shaper but how is this... If you have a big water hose and put a small nozzle on it you have presure. presure = thrust, thrust = speed. If you have better waves you have plenty of push, push = speed (no extra thrust needed). If waves are slow and mushy you need extra thrust for speed because of lack of push.
