When the original Furlex was introduced in 1983, it was not a pioneering project. The design included
features which improved on other manufacturers’ products to increase performance, function and
reliability. The first systems sold are still functioning well, providing ample proof of the design’s
effectiveness and long-term staying power. Furlex quickly became the market leader, a position it
still occupies today. Our success can also be put down to how we select a system for a specific yacht.
First we calculate the boat’s righting moment, which is a function of its displacement, ballast, beam
and draft. Then we use righting moment in combination with the rig type to calculate its power when
sailing, and the likely loads on the Furlex system.
Furlex is only sold through authorized local dealers who are able to cover all service requirements for
the customer, including assistance with assembly, the modification of sails or the production of new
sails.
This new Furlex model range incorporates improvements based on our extensive experience, and
represents the very latest development of the jib furling and reefing concept.
Furlex is supplied as a complete assembly kit containing all the components required.
The ball-bearing system of the halyard swivel features a load distribution facility, a unique
patented system which distributes loads over the entire ball race. This permits smoother furling
and considerably reduces bearing wear.
Furlex 100 S for Ø 6 mm forestay can be supplied with an optional external rigging screw.
The Furlex luff section has the same dimensions over its whole length. The entire luff is furled
in an even roll, right down to the tack of the sail. This is a requirement for satisfactory sail shape
when reefed.
The tack ring’s ”free turn” flattens out the sail, promoting an efficient shape when reefed.
Furlex is suited to both cruising and racing. The line drum and line guide are easy to remove if
you want to utilize the entire forestay length for racing.
The luff section has two luff grooves, allowing two jibs to be goose-winged when running down-
wind and facilitating fast sail changes for racing yachtsmen.
The prefeeder is always on hand to help when hoisting the sail.
The line guide fitting centres the line as it is wound onto the drum, and the flexible internal line
guard maintains light pressure on the line to ensure even distribution on the drum.
Furlex is manufactured by Seldén Mast, the world’s leading manufacturer of masts and rigging
systems.

3 Assembly preparations
3.1 Forestay attachment - guiding principle
Some Seldén forestay attachment options are shown below, illustrating the rules and exceptions.
For H dimensions, see Table 3.3.3.
The lower end of the Furlex system is fitted with a fork toggle as standard. This can normally be
attached directly to the boat’s forestay fitting at the stemhead.
Check that the lower bearing assembly and line guide do not interfere with the pulpit, navigation
lights or other deck fittings.
Fig. 3.2.a Fig. 3.2.b
Fig. 3.2.c Fig. 3.2.d
The guiding principle is that the forestay connections should allow sufficient articulation
in all directions. In most cases a toggle should be fitted between the Furlex stay and
the forestay attachment.

If the boat is fitted with a bow anchor, it may be
necessary to permanently raise the lower bearing
assembly to give the crew sufficient space for
anchor work. On Ø6 models, the adjuster shown
in table 14.1.1, or the extension link (table 3.3.3)
may be used for this purpose. Extension links for
Ø 4 & Ø 5 models are not stocked.
If the lower bearing assembly is raised by
means of an extension link, a Furlex toggle or
similar toggle with the same function should be
fitted between the link and the boat’s forestay
attachment.
Fig. 3.3.c
An extension link does not provide the necessary flexibility. It must always have a
toggle between it and the boat´s forestay attachment.

The lower bearing assembly can be fitted below deck inside an anchor well.
The advantage is that the sail’s luff length is maximized and the access around the forestay is improved.
The disadvantage is a more complicated route for the furling line, increasing furling resistance. The
diagrams below illustrate various methods of installation.
For the furling line to be wound evenly onto the line drum, the first turning point must be at least
250 mm (10”) away.
The tack should be located as close to deck level as possible.
Regardless of which option is chosen, the Furlex system must always be kept clear of the deck
well’s inside surfaces.
Avoid routing the line through an integral deck conduit, as this will increase the friction on the
furling line.
Use a large ball-bearing block to minimize friction losses.
The anchor well must be well drained.
To avoid damage to the Furlex system and the boat, the system must never be allowed
to come into contact with the edge of the deck or well when sailing.
Top edge of drum at deck level.
Large deck hole required for line drum.
Furling line led aft via turning block
and inset deck sheave box, then aft
along the deck.
Tack snap shackle at deck level.
Requires smaller hole in deck.
Furling line leads forward to an inset
deck sheave box, alternatively aft via a
block + deck sheave box.

Furlex fitted above deck, but with the forestay fitting
in the anchor well.
Use the Furlex extension toggle. For a larger gap, use
a custom-made stainless steel bar or rod stay. For Ø 6
only, the Furlex rigging screw or extension link may
also be used.
Short wire pendants are not recommended as forestay
forces may not be distributed evenly, and wire will not
resist the torque which may be produced.
1. Determine the rake of the mast with the fore-/backstay tensioned.
2. Slacken the backstay as much as possible, but make sure that any rigging screw is not unscrewed
so far that the threads are no longer visible ”on the inside”. The forestay setting should not be
adjusted. If there is insufficient adjustment in the backstay, and the forestay must be adjusted to allow
removal, first mark its thread with adhesive tape.
3. Pull the masthead forward using the genoa halyard. Secure the halyard using a ”D” shackle or tie it
to a strong deck fitting. For safety reasons, do not use the halyard snap shackle.
Always use a strong ”D” shackle or tie the halyard!
4. Take down the forestay. If it was slackened, adjust the rigging screw back to the tape marks.
5. Measure the forestay length (FL) with just enough tension to keep it straight.
6. Enter the measurement in Calculation Table 1 below, under the heading ”Your forestay”, in the row
marked FL.
7. Calculate the new wire length WL in Table 1. Refer to the column marked ”example” to see how

If the top extrusion is shorter than 400 mm (15 3/4”), the joint
will be too near the top. In this case replace the uppermost full-
length 2400 mm extrusion with the 2000 mm extrusion. In this
way the joint is moved 400mm (15 3/4”) down the stay. Adjust
the C and D measurements as follows:
Deduct 400 mm (15 3/4”) from the C measurement.
Add 400 mm (15 3/4”) to the D measurement.

Insert one end of a 144 mm (5 11/16”) spring in the upper hole of the
1000 mm extrusion, and slide the long joining sleeve up to hold it in
place. Remove the 200 mm (7 7/8”) joining sleeve from a 2400 mm (94 1/2 ”) extrusion.
This will be used later in the 2000 mm (78 3/4”) extrusion. Connect the 2400 mm extrusion and
the 1000 mm extrusion. Push the long joining sleeve up into the 2400 mm extrusion to secure the
connection spring. Continue pushing until the bottom of the sleeve is 50mm inside lower end of
the 1000 mm extrusion. A 50 mm (2”) gap is formed at this joint (as shown in fig. 4.1.c.), where
the sail feeder is to be fitted later.
Fit the short connecting spring (L=103 mm/4 1/8”) to the 1000 mm (39 3/8”) extrusion. The larger
hook must be on the free end. Push the long joining sleeve (L=1168 mm/46”) down, to hold the
spring in place and make space for the next spring.
Connect the remaining extrusions as detailed in table 3.6.1.

The extrusions are then fitted to the adapter of the lower bearing assembly. Hook the connecting
spring to the internal hole in the adapter. Then push the distance tube in the 2400 mm extrusion
down so that the joining sleeve bottoms in the adapter. The distance tube should be buried
approximately 100 mm (4”), about equal to half a length of a joining sleeve.

4 Assembly of the Furlex System
4.1 Assembly of the luff section

17
Fit the halyard swivel over the top end of the extrusion, slide it down as far as the sail feeder gap
and secure it in this position with adhesive tape. Fit the top guard and secure it with the two pre-
fitted screws. Tighten the screws until they bottom, but do not over-tighten.

1. Stretch the Furlex wire out by hand on a flat surface.
Be careful when you open the wire coil as it may uncoil quickly.
Note! Be careful when you open the wire coil !
2. Measure the wire from the centre of the hole in the terminal end fitting. Mark the measurement WL
carefully on the wire using a marker pen. (The WL measurement was calculated in Table 1 (3.5.1)
3. The wire is annealed and tapered, making it easier to fit into the extrusion. Do not cut the wire yet.
5. Feed the wire through the luff extrusions from the top until the eye of the end fitting stops against
the top guard. If the wire catches inside the extrusion, turn it counter-clockwise until it passes the
obstruction.
6. Put adhesive tape around the wire on both sides of the cutting mark to assist cutting. Check that
the distance between the cutting mark and the terminal’s lower edge is approx. 30-50 mm
(13/16”- 2”).
7. Cut the wire. Round the end of the wire using a file.
4.
Unscrew the eye, wedge and former from the terminal part.

9.
The core of the wire should protrude approx. 2 mm (3/32”) from the wedge.
Space the outer strands of the wire evenly around the wedge and push it into the socket so that the
strands are held in place. Tap the wire lightly so the outerstrands jam in the seat.
NOTE! Check that no strands slip into the slot of the wedge.
Fig. 4.2.d
10. Bend the outer strands inwards a little using a pair of pliers, or tap the strands with a small
hammer. In the latter case, rest the socket’s thread on a soft surface (wood or similar) to prevent
damage.
12.
Unscrew and check that the outer strands are evenly distributed around the wedge. If some strands
are crossed, correct their positions.
NOTE! Check that no strand has slipped into the slot of the wedge!
13. If assembly is unsuccessful and needs to be repeated, refer to the relevant sections of chap.

16. Check the length FL of the stay acc. Table 1 (3.5.1) & fig. 3.5.a. Check that the setting is the
same as the H-measurement as in table 1.
The hook is connected to the rubber cord acc. to fig. 11.1. Feed the cord through the starboard sail
groove as shown in fig. 4.2.k and then through the slot in the lower bearing assembly.
Fix the hook in position.
Use a small screwdriver to pull the top of the
rubber cord down the luff groove.

It is most important that the
prefeeder is correctly fitted,
or it will not function
correctly.
Tension the cord as hard as possible and tie the
pre-feeder to the cord as shown, 300 mm (12”)
from it’s exit sheave. Tighten the knot and cut
off excess cord.
CAUTION: If the cord is too loose the pre-
feeder may be thrown out by centrifugal
force when the system rotates.
If the sail has a tendency to come out of the
pre-feeder, reduce the gap width by squeezing
the two arms toghether with a pair of pliers.
Max. 300 mm
