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.

Full-Length Foil

Feeder

CBA

Adjuster Tube

Actual adjuster tube will have 12 to 14 adjuster holes. Line up the foil so it is just above the midpoint of adjustment.

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.

Assembly Cutting/Drilling Top Foil

Determine top foil length using charts or by laying foils alongside wire. IMPORTANT! Confirm that you are using the correct unit size worksheet. Be sure to lay foils, lower unit, and leg kit alongside stay to confirm length before cutting.

Use tape to mark foil. Cut foil to length.

Tool: hacksaw

be at the top when installed. You will be drilling each side near the top.

Lay top foil alongside cutoff piece. Use locking pliers to clamp foils together at the interior flat surfaces opposite the sail grooves.

Use a flat metal object (i.e. metal ruler) to scribe lines on one side of foil. Leave foils clamped for drilling.

Tools: straight edge, locking pliers
