Selden Furlex 100S — Owner's Manual

Luff & Wire Terminal

• Assemble on a horizontal surface from the lower bearing assembly up. Short spring (L=103 mm) in the 1000 mm extrusion, long joining sleeve (L=1168 mm) to hold it; long springs (144 mm) at the other joints. Leave a 50 mm gap at the 1000/2400 joint for the sail feeder.
• Fit the halyard swivel down to the sail-feeder gap (tape it), then the top guard with its two screws (bottomed, not over-tight).
• Mark WL on the wire from the centre of the eye, feed the wire down from the top (turn it counter-clockwise if it catches), check 30-50 mm between mark and terminal edge, tape and cut.
• Sta-Lok-type terminal: wedge over the 7-strand core with ~2 mm protruding, strands spaced evenly, former in the eye part, locking adhesive, screw up; check no strand is in the wedge slot; final 2 or 3 drops of adhesive.
• Prefeeder cord through the starboard groove and lower-bearing slot, tensioned hard, prefeeder tied 300 mm from its exit sheave.

Drum, Halyard & Furling Line

• Line drum and line guide are easiest to fit with the Furlex on the boat; line guide midway between the flanges, aligned with the first lead block.
• Halyard angle 5 - 10° to the forestay; less risks halyard wrap. Fit the two bronze halyard leads (Ø 5.3 mm holes, self-tapping M6 screws with grease, insulator sheet) or a sheave box (wire Ø 4/Ø 5 or rope Ø 8/Ø10: 505-004-10 AL-45, 505-006-10 AL-70). Replace leads at 50% wear.
• Keep the spinnaker halyard clear (round the upper shroud and aft of the spreaders).
• Wind approx. 25 turns of line onto the drum by hand: UV strip on starboard = line exits port, turn clockwise; UV strip on port = counter-clockwise.
• First turning point at least 250 mm (10") away (below-deck installs). Final cockpit block not included: swivel block, working load not less than 3000 N (675lb), plus a cleat. 4 stanchion blocks for 25 mm (1") tube.

Hoisting, Furling & Reefing

1. Tension the forestay (backstay, runners) before hoisting.
2. Turn the tack ring counter-clockwise if the line exits port, clockwise if starboard; tack to the snap shackle.
3. Hoist in the starboard groove if the line exits port (and vice versa), luff through the prefeeder; tension until a vertical crease appears, then ease until it goes.
4. Furl tightly with some tension on the leeward sheet; 3 - 5 turns should remain on the drum with the largest sail furled.
5. Check swivel at least 20 mm (3/4") below the top guard and the 5-10° angle, then mark the halyard. Never tension the halyard with the sail reefed or furled.
6. Reefing (close to beam reach): ease the sheet until the luff just flaps, pull in the furling line, belay. Adjust the sheet lead as needed.

Racing: remove line guide and drum (chap. 17.3-17.4) and sail feeder, lower the halyard swivel and refit the feeder for a twin-groove headfoil.

Forestay Length & Maintenance

• Rigging screw (Ø 6 only): one wrench on the terminal flats, one on the bronze nut; never force past the stop. Without rigging screw, lengthen with toggles – on a 10600 mm forestay a 40 mm toggle moves the masthead 127 mm aft.
• Rigging: tension the forestay to 20% of wire breaking load (on a masthead rig approx. 15% of the backstay's, same diameter). Split pins opened ~ 20°.
• Yearly: rinse, then grease the lower bearing (screw A, tack ring recesses B & C, slot D) and the halyard swivel (recesses E and F in the eye ring) with the supplied grease.
• Wash with mild detergent and rinse; silicone-free polish on the extrusions; never wrap a damp Furlex in plastic; store dry or with centre sections raised where it freezes.
• Do not dismantle the halyard swivel or lower bearing assembly (loose balls) – dealer service.
