Ordering Asymmetric Reflex Furling
Use for asymmetric free-flying spinnakers, cruising spinnakers, and gennakers that have a loose positive 
luff that is longer than the leech.
Boat Requirements
1. Spinnaker halyard
2. Attachment bail or adjustable tack fitting on a bowsprit or bow extension that allows the furler 
  
to clear the forestay and bow pulpit.
1. Determine System Size
Refer to “Typical Boat Length” and “Maximum Sail Area” on unit pages to select the correct size. 
Note: if you plan to use the system for code zero sails, the loads will be higher so the maximum boat 
length and sail area are smaller.
2. System Components
The Reflex furling system for asymmetric spinnakers includes all components necessary for one 
asymmetric spinnaker: one drive unit with snap shackle attachment, tack swivel, head swivel, torsion 
cable, set of cable clamps.
For each additional sail, order these components separately so you can easily switch furled sails 
using the quick-release T-slot: one tack swivel, head swivel, Reflex torsion cable, and set of 
cable clamps.
3. Determine Reflex Torsion Cable Length
Each system includes a length of torsion cable. To purchase the correct system including the right 
length of cable, determine your Full Hoist Dimension (FH). To do so, measure the distance between 
the sail attachment points at the top of the rig and the bow fitting or fully-extended bowsprit. Make 
sure the kit you select includes more cable than your FH measurement.
4. Attachment to Boat
The standard Reflex furling system for asymmetric spinnakers includes a threaded snap shackle 
adapter. To change to D shackle or soft-attach 2:1 adjuster see chart at right.
5. Ordering Furling Line
The Reflex furling system requires continuous furling line. Talk to your rigger about furling line con-
struction using a structural cover over a nonstructural core. Note: have the rigger capture the aft 
block in the loop before splicing. The furling line loop can load into stanchion leads and drive unit 
after it is spliced. 
Refer to chart below for line size and length. Double the loop length and add enough length for the 
overlap in the end-for-end splice.
