Preassembly Foil Length
Line up bottom foil so foil clamp is
centered or just below center of
notches in bottom foil.
Confirm foil length by laying foils alongside stay with turnbuckle components. Pull stay out so it is straight. Attach
Harken toggle to bottom of stay using crosspin. Adjust turnbuckle so that length of stay with Harken toggle will fit
boat. Ideally, turnbuckle will be half to two-thirds open to allow for rig adjustment.
Line up lower unit so base of unit lines up with toggle housing.
Attach one link plate to lower unit. Line up lower unit so link plate hole lines up with crosspin in Harken toggle.
Make sure toggle is tensioned when measuring.
Note: Position top foil so that with top
cap the foil will ride about 3" (76 mm)
below terminal. If wire fitting at top of stay
is swage, foil must ride just below shoulder
of swage. Mark cut line on foil. Wrap tape
around foil as a guide so cut is straight.
Determine where cylinder will ride when
sailing. Shown fully closed.
