Rigging

[Mad Frog]

Would you know where I could find advanced guidance on rigging for slalom boards:

Mast Position on board when considering strong winds, board control, sail size, fin size.

Harness Position: Scientific approach to harness position rather than "look & feel" approach, eg Position of centre of harness lines to the % of the boom (given sail size etc)

Fin Size & shape: Determining what fin to use -> Sailor Weight, Board Size, Sail Size, Sailing objective (Upwind vs crosswind speed)

Foot strap positioning

With thanks

Mad Frog,

What board are you using??

[Mad Frog]

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
Best regards
Marc
