Commissioning
Leading the Furling Line to the Cockpit
April 2000 Unit 3.25 MKIII 28
The furling line is attached to the drum and led to the cockpit in five steps.
Use Harken bullet blocks for the forward and intermediate lead blocks. Use a #009 Hexaratchet ® or other ratchet for
the aftermost lead block. Harken part #969 is a lead block kit with three #001 2.25" bullet blocks; one 011 block; and a
5" (127 mm) cleat. Use the lead block kit or choose the best configuration of blocks for your needs.
1
Pass the rope through the hole in the top of the
drum and tie a small overhand knot. To prevent
binding, make the knot as small as possible. Pull
the knot securely down onto the drum assembly.
“Charge” the system by turning the foils to wrap
line on the drum.
Tip: The position of the suncover on the sail determines the direction of rotation: Suncover to starboard - “charge” by turning clockwise. Suncover to
port - “charge” by turning counter-clockwise. Keep tension on the line while “charging”.
2
Loosen the line guard assembly screws and align the opening in the basket so the furling line leads properly at all
times. The angle at which the line exits the basket changes as the amount of line on the drum changes. Check for
chafe with varying amounts of line on the drum before locking the unit.
Tip: When line is wrapped clockwise on drum the opening will look “off center” to starboard. The opposite is true for counterclockwise.
The furling line may be led down either side of the boat.
3
Position the forward block so that the line enters the drum at right
angles to the headstay and is centered vertically in the opening.
Move the block fore or aft to adjust the line vertically in the opening.
Improper positioning will result in chafe or cause line to wrap
unevenly on the drum. In many cases, proper placement cannot be
achieved by using a stanchion mount lead base and the forward lead
block must be attached to a padeye mounted on the deck.
4
Mount a 009 Hexaratchet (or other configuration of ratchet block)
as the after lead block to insure proper drag on the furling line to
prevent line overrides in the drum.
Tip: Position the ratchet block so the line turns at least 90°.
Position a standard horn cleat in a convenient location in the cockpit.
5
Lead the line through the forward and after lead blocks. The after
block should be a little Hexaratchet. If the line has been led cor-
rectly you should hear a clicking sound. Then, position the intermedi-
ate blocks to keep the line clear of the side decks to insure a fair lead.
B Position of forward lead block
(Harken 125 or 168) is critical
as a proper lead prevents line chafe.
C Intermediate lead blocks hold the line near the gun-
wale. The number and placement of these leads depends
on your boat length and configuration.
D Aft-most lead block must be a Harken little Hexaratchet to provide the proper
line drag while furling. This block should be placed to lead the line to a cleat in
the cockpit. If the line has been led correctly you should hear clicking when you
pull the line. If not, the ratchet switch may not be engaged or you must relead
the line through the block in the opposite direction.
The furling line lead changes as the
amount of furling line on the drum
changes.
L'angle de sortie de la drosse varie
en fonction du nombre de spires
emmagasinées sur le tambour.
Der Eintrittswinkel der Reffleine
ändert sich mit der Menge der auf-
gewickelten Reffleine.
La direzione con cui la cima di
avvolgimento entra nel tamburo
cammbia ini funzione della quantità
di scotta avvolta.
Furling line must enter drum at
right angles to headstay.
La drosse doit entrer dans le tam-
bour perpendiculairement à l'étai.
Die Reffleine sollte im 90° Winkel
zum Vorstag auf die Trommel
laufen.
La cima di avvolgimento deve
entrare nel tamburo formando
con lo strallo l'angolo giusto.
A 061 stanchion mount bases
provide an ideal attachment method
for furling line lead blocks. The ball
joint socket accepts most small
boat swivel blocks, including ratchet
blocks.
