The following is for FF6 systems, FF4 systems follow 25. A) 

25. B) For the FF6 wire halyard, apply the Nicopress double 
oval sleeve then form a loop and insert the thimble in the 
middle. Crimp down on the Nicopress using a crimping tool. 

26. Attach the halyard to the head of the sail. The FF6 will be 
attached with the supplied halyard shackle, a shackle is 
optional for the FF4. 

27. Feed the luff of the sail into the sail-feed slot while 
hoisting the sail by pulling on the messenger line which is 
attached to the de-cored end of the halyard (step 6). 

28. Remove the messenger line once the sail is fully hoisted 
and tie off the halyard on the anchor shackle on the spool. 

Note: Always remember to reattach the messenger line when 
lowering your sail. 

29. Tension the sail by tightening the tack tension line to the 
second shackle on the spool and hoisting the sail tight by 

pulling on the halyard, using a winch shouldn’t be required.

 

30. Furl in the sail by pulling on the furling line and keeping 
tension on the jib sheet. 

 

 

SAILMAKER INSTRUCTIONS 

Sails require #6 luff tape to be compatible with all CDI furlers 

Webbing at the head and tack of the sail is recommended 
instead of metal grommets for smooth furling but is not 
required. 

 

RIGGING INSTRUCTIONS

 

The CDI flexible furler system cannot be mounted above the 
turnbuckle as it can cause it to unscrew and dismast. If more 

clearance is required, it’s recommended to add link plates.

 

The FF4 and FF6 systems are compatible with 1/4”, 5/16”, 
3/8” and 7/16” turnbuckles with a threade

d swage-end and a 

T-bolt toggle. 

Note: Most Navtec turnbuckles do not work and are not 
recommended 

as they’re often too large to fit inside the drum

 

T-

bolt fittings are preferred, “i

-

bolt” fittings may not fit

 

Cotter pins should be used to lock the turnbuckle, not locknuts 
as these can unscrew and cause dismasting. 

Toggles are required at the bottom of the headstay, any 
secure fitting at the top of the forestay will work but a toggle 
is also recommended. 

NOTES ABOUT SAILING 

The tension on the luff 

doesn’t need to be high and should 

only be tight enough to removes any creases in the sail. 

When sailing reefed, the jib leads should be moved forward 
to maintain proper sail shape and avoid the furler from rising 
off the bearing. 

To furl your sail, always keep tension on your sail

s jib sheet 

while reefing the furling line. 

 

 

NOTES ABOUT TRAILERING 

When trailering, strap the furler to the mast in a horizontal 
position and support the end with the hardware by using a 
support extension ie. 2x4 or PVC tube 

Keep the extrusion as straight as possible, do not let either 
end sag or twist.

 

 

 

MAINTENANCE  

The only maintenance required is to rinse the furler system 
including the ball-bearing assembly if applicable, with fresh 
water 1-2 times per year. Clear out any salt or dirt that may 
have accumulated. 

Note: Lubricants are not required but Teflon sprays or dry 
lubricants are acceptable if needed. 

 

 

STORING YOUR FURLER 

Storage is best accomplished by strapping the furler to the 
mast in a horizontal position and supporting the end with the 
hardware by using a support ie. 2x4 or PVC tube 

When storing, avoid making sharp bends in the extrusion. 
This can become permanent after a period of time and is not 
covered under warranty. 

It is not necessary to remove or recoil your extrusion, doing 
this over long periods of time can become permanent and is 
not recommended as the furler ages. 

Avoid exposing the furler in temperatures above 140F/60C
