FOIL CUT LENGTH
Foil cut length is based on pin-to-pin length as measured from cen-
ter of upper pin (attaches the stay to the mast) to center of lower
pin (attaches the furling unit to the boat). Measurement includes the
masthead toggle.
To check foil length, lay foils alongside stay before
cutting top foil.
