Sailmaker's/Rigger's Instructions - CDI Flexible Furler 2 Installation & Operating Instructions Manual

SAILMAKER'S INSTRUCTIONS
Luff tape required is #6. Sail luff deduction is 13" from pin-to-pin
length.
We recommend use of webbing at the head and tack instead of
metal grommets. This allows the sail to reef and furl more evenly.
The Flexible Furler can not be mounted above the turnbuckle as
this potentially puts excessive torsional stress on the turnbuckle.
This, in turn, could lead to the unscrewing of the turnbuckle and
dismasting. To raise the system, shorten the headstay the desired
amount and install linkplates under the turnbuckle.
The FF2 can only be used with 1/4" and 5/16" turnbuckles.
Turnbuckle must have threaded swage stud and T-bolt and toggle.
Stays with other fittings at the bottom (eyes, jaws, etc.) must be
altered as the antirotation strap will not fit using these other
fittings. We recommend replacing closed body, lock nut
turnbuckles with open body, cotter pinned turnbuckles. Lock nuts
are not a satisfactory way to lock turnbuckles. Any improper
installation could lead to an unscrewing torque on the turnbuckle
that could lead, in turn, to the loss of the mast.
Toggles are recommended at the top of the forestay as well as the
bottom.
