Size Check
1. Check headstay and clevis pin dimensions in chart below.
WARNING! Do not drill boat's chainplate or toggle. This may result in rig failure. Use the correct size toggle and clevis pin.
2. Harken does not recommend drilling boat’s chainplate or toggle. In some cases bushings are available to fit boats with smaller clevis pin sizes.
3. Will drum fit on bow? See page 6. If necessary, use an additional toggle to slightly raise unit.

1. Harken toggle assembly required. Sold separately.
2. Mating turnbuckle components must be purchased separately.
3. Headstay may require cutting and shortening to fit Harken toggle. Headstay may remain uncut by replacing lower stud of turnbuckle with stud/eye thus eliminating extra toggle.
4. Rod rigging requires Harken rod adapter stud.
5. Order Harken 7404 Lead Block Kit. Fits 1" (25 mm) stanchions.

Preassembly Dimensions/Sailmaker's Instructions
Luff Length
Note offsets above and below the sail. A shorter luff may be required if a halyard restrainer is necessary
(page 26) or a toggle or long toggle assembly is used to raise drum. If the luff of sail is not long enough to put the halyard swivel near the
top of the headstay foil, a pendant must be added (see page 26).
33/4"
(96 mm)
61/4"
(158 mm)
Tack Setback
Note setback for the tack shackle and cut the sail accordingly.
Luff Tape Size
6
Unit 0 requires #6 (
/32" or 5 mm) luff tape.
Luff Tape Length
Cut off top of luff tape so it is 18" to 24" (450 to 600 mm) below head of sail. This allows head to lag behind rest of sail to help flatten sail. It will also help head to roll more smoothly. Note feeder height and extend the bottom of the luff tape downwards so
it is below the feeder. This will prevent the luff tape from catching in the feeder as the sail is lowered.
Tack and Head Shackles
Make sure tack and head shackles fit the sail rings. The minimum inside dimensions

Use dimensions of Harken toggle below to build stay to correct length.
Tip: Turnbuckles should be 1/2 to 2/3 open to allow shortening for new wire stretch and for fine-tuning mast rake.

Most boats have a chainplate with a single tang. If boat has two plates forming a jaw, reverse eye/jaw toggle so eye is down.
IMPORTANT! Remove black plastic caps and install them so crosspin will be at 90 degrees to lower clevis pin.

Preassembly Confirm Foil Length
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. Make sure toggle straps are straight. 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 drum assembly so holes below drum line up with holes in Harken toggle. Make sure toggle is tensioned when measuring.
Line up bottom foil so foil clamp is just above or below center of notches in bottom foil.
Note: Position top foil so that with top cap the foil will ride 1/2" (13 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.
If 7301 Halyard Deflector is used, add 1" (25 mm)
10 MKIV Unit 0 4/05/07
Assembly Top Foil
Cut foil to length using a hacksaw.
Deburr inside edge using a rat-tail file.
Prepare top foil for drilling.
Tip: Mark top foil to distinguish from cutoff piece.
Scribe line on top of foil to mark drill holes. Lay top foil alongside cut-off piece and use a flat metal object (i.e. metal ruler) to scribe top line of foil.
