Thinking of having a custom surfboard made. An important point for me is upwind ability. Think this is important as if you can get back up wind quickly, you can ride more waves! Gonna have medium volume (around 25 ltrs) and 5 fins (so I can go 4 fins if I want more upwind ability). What is the main thing to include for upwind? Is it straight sides (so front and back come out fairly quickly - perhaps a fishtail- to give a straight-sh edge)?
I weigh around 76kg or 170 pounds.
Thanks
