On board pictures are critical to sail analysis. Taking pictures from the center of the foot gives us the ability to catalogue, document and compare sail shapes.
Documenting and comparing sail and trim settings to creat a baseline that performance data can be documented to find the fastest sail shape setting possible.
Developing a tuning guide that is specific to your boat and sail combination. Every boat is different. Documenting changes will provide the fastest way to replicate setting for the conditions.
Mast bend deflection analysis is used to compare setup and help optimize tuning guide specific to the boat.
Documenting sheet tension, Jib car leads, halyard tension, wind strength, and wave state will help finding the optimum setting for best up wind VMG.
Leech profile analysis helps with matching rig settings and sail profile to best maximize Jib performance.
