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.

®

stud after foil is assembled.

3. Rod adapter nosepiece for Harken rod adapter stud: Threaded nosepiece must

Options for Snaking Stay into foils

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.

WARNING! Using a threaded nosepiece with only adhesive at the

upper rod eye terminal may result in headstay system failure.

Make sure there is a mechanical lock.
