Position 2660 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.
Note: As furling line lead changes, make sure line
doesn’t chafe against line guard. Rotate line guard
if necessary.
2660 Forward Lead Block
Install 2600 intermediate lead blocks so line
is inside stanchions.
Number and placement of leads depends on boat
length and number/configuration of stanchions.
2600 57 mm Carbo Intermediate Lead Blocks
Mount 2670 Carbo ® Ratchet block as furthest-
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
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.
2670 75 mm Carbo ® Ratchet Block
Install so line is angled as shown.
Furling Line Cleat
Furling line lead changes as amount
of furling line on drum changes.

Run line through enclosed window in guard and into hole in
bottom flange of spool. Tie a small overhand knot and pull it
up under drum assembly.
WARNING! Lead line through enclosed window. If
line is led through opening between two enclosed
windows, it can ride above line guard and jam furler
which can cause loss of control of boat.
Note location of sun cover. With no sail on unit, charge system by rotating furler to wrap line on drum. Leave a
comfortable-length line tail in cockpit. Fine-tune line length on all points of sail after sail is hoisted and set.
Tip: Sun cover to starboard—turn clockwise to charge. Sun cover to port—turn counter clockwise.
Tension line while charging.
Mount lead blocks
Furling line can be led down either side of boat. If boat is in slip, consider mounting
opposite dock.
