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
