Optimized halyard swivel
A Dyneema® loop is fitted to the ring of the halyard swivel in which the halyard shackle is attached.
The loop is surrounding the ring which makes for load distribution and reduced furling resistance.
Tack swivel
The ”free turn” of the tack ring allows for the luff to be furled one turn before the tack. This makes for a flatter
and more efficient sail shape when the sail is reefed. Reduced tack ring diameter in combination with a short
shackle – or an optional soft shackle – reduces the furling resistance.
Prepared for soft-shackle
The tack ring and halyard swivel eyes are prepared for using Dyneema® soft shackles. All surfaces are smooth
and nicely rounded.
Aero grooves
Similar to the dimples on a golf ball, the Furlex AERO groove system reduces drag and creates better
aero dynamic flow around the luff extrusion.
Roller bearing
A roller bearing between the main ball bearings of the drum unit distributes the load from the furling line over a
large bearing area. This makes for lower resistance when furling.
Floating connectors
The 316 stainless steel connectors are subjected to vertical loads only and no torsional loads.
Torsional loads are taken by the join pieces alone which leaves the connectors “floating” inside the join thus
reducing wear inside the joins.
Air gaps
Every join in the system is made with a nominal gap which means the extrusion ends will never get in contact
with each other. This way there will be minimum chafe and no aluminum deposits staining on your new sail.
Jaw lock
Double screws through the rope and locking jaws ensure a bullet proof locking of the furling line.
Detachable swivels
Both the halyard swivel and the drum unit can be easily removed from the foil for off-season storage.
This facilitates storing the foil with the mast and makes handling easier.
Three options for wire termination
Furlex 404TD can be delivered with three wire terminals. The standard version is a Sta-lok wire eye terminal.
An alternative is a Sta-lok wire terminal fitted to a rigging screw for adjustability of the forestay length. The
stroke is 100 mm. The rigging screw is integrated in the torque tube and does not affect the tack height of the
sail. A third alternative is a swaged stud terminal – a common solution for large volume OEM deliveries.
Small drum diameter
The diameter of the line drum is small to allow for an installation as far forward as required. For genoas with
large LP-measurements, the Furlex S-series line drum and line guide assembly can be used in case the standard
TD-series drum does not accommodate enough length of furling line. This requires more room below deck.
