That's the issue. I'm constantly switching boards and swapping booms and sails around. I was therefore wandering whether there was a scientific approach to rigging (esp Mast & Harneess line position) instead of a "trial and adjust" approach? I tried using reference points, but they wash/ fade away!
Small Boards: Sonic 95, Modified Kombat 95, Custom Falcon 90 (use the sonic in flat and falcon in chop)
Largish: iSonic 125, Falcon 131 (Mostly Falcon)
Many thanks if you have any hints
