Genoa Shape Controls

Quick Reference Guide


Genoa Sheet:

Affects twist, depth and angle of attack. Adjust to shift gears and help steer the boat

Genoa Halyard:

Controls draft position. Begin with halyard just tight enough to eliminate horizontal wrinkles. Has more of an effect on sail made with stretchier material

Backstay Or Runner:

Limits headstay sag. Controls overall depth of genoa, and effects draft position. More sag gives more power and makes steering easier

Genoa Lead:

Fore-and-aft position alters twist. Athwartship position affects twist and sail efficiency


Should break evenly from top to bottom. Leeward telltales should (almost) never stall
