7401 Forward Stanchion Block
Position 7401 Forward Stanchion Block so line enters
drum at right angles to headstay and centers vertically
in opening. Install so line is inside stanchion.
Correct block position is critical to even line
spooling and ease of furling.
7403 Outboard Stanchion Blocks
Install 7403 Outboard Stanchion Blocks so line is
outside stanchions.
Number and placement of leads depends on boat
length and number/configuration of stanchions.
7402 Ratchet Stanchion Block
Mount 7402 Ratchet Stanchion Block as farthest-aft
lead to prevent line overrides in drum when unfurling.
Position ratchet block so line turns at least 90°.
Install so line is inside stanchion.
Lead line through block so ratchet makes a clicking
sound when pulling line to furl sail.
Tip: Make sure ratchet switch is in “ON" position.
If there is no clicking sound, lead line through block
in opposite direction.
Lead line to furling line cleat in cockpit.
HCP168 Furling Line Cleat
Install so line is angled as shown. Use #10 (5 mm)
fasteners.
Note: As furling line lead changes, make sure line
doesn't chafe against line guard. Rotate drum
assembly if necessary, see page 22.
