For smaller sailboats, the Facnor STG is a wire structural furler, light and easy to install. Just add a metal wire with terminals to the STG furling kit including a continuous
line drum, deck+mast toggles, head swivel connected to the mast, and a halyard swivel connected to the sail head/halyard.
The Facnor structural furlers can be assembled with a classic thimble fitted into a jaw or with a threaded thimble screwed into the drum. The continuous line drum is made
from a single aluminium block that is CNC machined in order to offer a high resistance.

Facnor adapted the racing structural furler developed for ocean Open 60’
to 24 to 30 ft sailing boats. These furlers are in/out systems for Solent or
small Genoa. They give the possibility of hoisting quickly a sail fitted with
hanks as on any conventional forestay. This Facnor system is especially suitable
for racing yachts.
Facnor STG In / Out Systems
Unlike the headsail furling and reefing system, but like the Gennaker furler, the structural wire furler does not
allow reefing of the sail. It is an in/out system. The sail set on structural wire furler can be fitted with hanks
or zip luff. The furling principle is simple: the continuous line drum transfers the rotation to the tack of the
sail that furls round the forestay. After a few turns, the rotation is quickly transferred to the top of the sail. With
the halyard swivel the sail can be quickly hoisted and lowered the sail as requested.
Facnor Wire Furlers - Maximum Luff & Lightness
The structural wire furler offers the same advantages as the continuous
line drum: a constant furling power, a maximum luff thanks to the low
profile drum that keeps the jib tack low. Extra feature: the saving in
weight compared to a classic drum is around 10kg less than a conventional
furling system. Ideal for racing boats!
Facnor STG 3T / 4T Structural Wire Furler
Facnor supplies the First Class 7500, produced by Bénéteau. This boat has
been designed by Finot- Fauroux architects in partnership with the French
Sailing Federation. The choice of the Class 7500 illustrates the perfect suitability
between the STG 3T / 4T and the racing monotype
boats.
The structural furler holds the mast unlike the Facnor Gennaker furler. Therefore, it supports the forestay loads. The principle
is the same as the custom structural furlers installed on ocean racing mono- and multi hulls. However, the custom
products are fitted with anti-twist fibre cable. The Facnor STG 3T only requires a standard monotoron wire forestay.
