Preassembly
Confirm Foil Length
Confirm foil length by laying foils alongside stay with turnbuckle components. Pull stay straight. Attach Harken
toggle to bottom of stay. Adjust turnbuckle, if used, so that length of stay with Harken toggle will fit boat. Ideally,
turnbuckle will be one-half to two-thirds open to allow for rig adjustment. Temporarily clamp short or long leg kit
to bottom of unit. Line up:
A. Bottom of full length foil with holes in adjuster tube. Set adjuster tube just above the mid-point of adjustment
range.
B. Holes at lower end of adjust tube with drum assembly holes.
C. Lower holes in leg kit line up with eye in toggle.
Lay all foils out alongside stay and confirm that there will be enough space between the bottom of the marine eye
and the end of the top foil. If necessary, go to lower end, reposition the adjuster tube and lower full length foil
to another position. Confirm that there are two holes for the foil and one for the feeder.

Adjuster Tube
Full-Length Foil
Actual adjuster tube will have 12 to 14 adjuster holes. Line up the foil so it is just above the midpoint of adjustment.
Tip: Check to see if the foil fits over the marine eye. If yes, assemble all foils and lower unit following
instructions. Measure and cut the top foil when all other foils are assembled.
