Page 2: Introduction
All safety-related information is indicated by the following symbol: The manual covers two different Furlex sizes, 400 S and 500 S. The Furlex 400 S is designed for use with a 12 or 14 mm forestay, while the 500 S system is designed for a 16 mm forestay and has a stronger luff extrusion and halyard swivel. -

3 Assembly preparations 3.1 Forestay attachment - guiding principle 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 attachments. 3.2 Mast attachment Some Seldén forestay attachment options are shown below, illustrating the rules and exceptions. -

Page 12: Assembly Below Deck
3.4 Assembly below deck 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. -
Page 13: Calculating The Length Of The Forestay Wire
Furlex fitted above deck, but with the forestay fitting in the anchor well. Use a Furlex extension link (not 500 S). For a larger gap, (or for 500 S,) use a custom made stainless steel bar or rod stay. See specifications on page 11. Short wire pendants are not recommended as forestay forces may not be distributed evenly, and wire will not resist the Fig. -

Assembly of the 500 S luff section differs from the 400 S in the following respects: The sail feeder of the 500 S is not a separate component, as shown in fig. 4.1.b, but is cut into the 1000 mm (39 3/8”) luff extrusion. - Page 17 Fig. 4.1.e Fit a joining sleeve into the next 2400 mm (94 1/2”) extrusion together with a connecting plate. Connect this to the lower extrusions. Using a spare joining sleeve, push in the distance tube from the top until the lower joining sleeve touches the distance tube below the join.

4.2 Fitting the wire terminal (or rigging screw) 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. - Page 19 Fig. 4.2.c Slide the wedge over the core (7 strands) of the wire . The core of the wire should protrude approx. 3 mm (1/8”) from the wedge. Remove the adhesive tape from the top eye terminal. Space the outer strands of the wire evenly around the wedge and bring down the socket so that the strands are held in place.

6.3 Routing of the furling line The line should be led aft to the cockpit via the lead blocks included in the Furlex package. The lead blocks are mounted on stanchions and the pulpit. See fig. 6.4.a–6.4.f for how to fit the leadblock. The lead blocks are not suitable for mounting on angled stanchions or pulpits. -

Smaller foresails such a cruising (working) jib will have a higher clew, giving better visibility under the sail, easier passage over the guard rail and less exposure to waves breaking over the foredeck in heavy weather. This type of sail often requires less adjustment of the sheeting position when reefed (See Chapter 12, ”Reefing”). -

Page 35: Sailing With Furlex
11 Sailing with Furlex 11.1 To hoist the sail The forestay must be properly tensioned each time the sail is hoisted. You should therefore tension the backstay and any running backstays before hoisting the sail. After the sail i hoisted, the back stay or running back stay tension can be relaxed again as required. -
Page 36: Unfurling The Sail
8. Hoisting the sail in the correct groove through the sail feeder. If the furling line exits on the ”port side” of the line drum, the sail should be hoisted in the ”starboard groove”. If the line exits on the ”star board side”, use the ”port groove”. Hoisting the sail in the ”correct” groove reduces initial resistance when furling the sail, which then has less of a ”fold”... -
Page 37: Furling The Sail
11.3 Furling the sail 1. Release the windward sheet and ensure that it can run freely. 2. Furl the sail by pulling the furling line. Release the leeward sheet but keep a little tension on it, for example by placing a turn around a winch. It is important to furl the sail tightly and evenly, as a sail which is furled too loosely can blow out a little in strong winds. -

Page 39: Setting A Reefed Sail From The Furled Position
12.3 Setting a reefed sail from the furled position You will achieve the best sail shape by first unfurling the sail completely and then reefing down … to the appropriate size. Pull in the furling line and keep the sheet well tensioned. The sail will then form a tight roll and its shape will be improved. -
Page 40: Furlex For Racing
13 Furlex for racing Many racing yachtsmen have exploited the advantages of the jib furling and reefing system … with great success. The sail can be partly furled before the start, giving good visibility and easy manoeuvring of the boat. Just before starting, the sail is unfurled and the boat crosses the line under full sail. -

Page 43: Maintenance Of The Furlex-System
15 Maintenance of the Furlex-system To ensure that the system rotates easily and functions satisfactorily year after year, regular maintenance should be carried out. This should be done once a year, or perhaps when the boat is unrigged at the end of each season. -
Page 44: Cleaning The Furlex
15.3 Cleaning the Furlex Wash and rinse the entire Furlex-system with fresh water and a mild detergent to remove dirt and salt crystals. Note! Some detergents contain substances which can cause aluminium to corrode, so it is important to rinse all detergent off thoroughly. When the parts have dried, the anodized surfaces of the luff extrusions can be treated with a silicon- free boat polish or wax. -
