  • Page 3: Introduction

    1 Introduction Congratulations on the purchase of your new Furlex jib furling system. Furlex jib furlers have been engineered and manufactured by Seldén Mast since 1983. The system has been continuously developed over the years and we are now launching the fourth generation Furlex, the most sophisticated single line jib furling system so far. 1.1 Key features Maximized luff length The luff extrusion foil shape remains unchanged all the way down the furling unit.

  • Page 4: What's Included

    1.2 What’s included? Basic pack / Extended pack The Furlex system consists of a basic pack with drum unit, halyard swivel, sail feeder, bearing halves, top guard and furling rope. The Extended pack also includes halyard leads, stanchion blocks and pre-feeder pack - accessories that will make your system work even better on your boat.

    1.4 Safety precautions The information in this manual must be followed carefully to avoid damage to the system and to aviod the risk of personal injury. The warranty is only valid if the system is assembled and operated according to this manual. Please read the entire manual before assembly! 15-20°...

  • Page 6: Sail Information

    1.5 Sail information Your sailmaker has all the necessary sailmaker information through the Seldén Sailmakers Guide. The Sailmakers Guide can be downloaded from www.seldenmast.com Note that if you want to use an existing sail, it will need some modifications:. • The luff length needs to be adjusted.

  • Page 7: Assembly Preparations

    Assembly preparations 2.1. Tools Before starting with the assembly, make sure you have the following tools available: • Socket screw driver • Hack saw • Torx bits • Measuring tape • Knife • Hammer • Pencil If Sta-lok is to be fitted you will also need: •...

  • Page 8: Wire Length Calculation

    2.3 Wire length calculation If a Sta-lok terminal (with or without rigging screw) is included, the wire is supplied over-length. The wire has a swaged eye terminal on one end while the other end is open (= without terminal). If your Furlex is supplied with a fixed-length forestay, with a swaged eye on one end and a swaged stud in the other end, skip this part and go directly to 2.4.

  • Page 9: Top Extrusion Length Calculation

    2.4 Top extrusions - length calculation The Furlex luff extrusion consists of a number of shorter pieces. Starting from the bottom there is a 1000 mm (39 3/8”) luff extrusion connected to the drum unit and extending up to the sail feeder. Then, from the sail feeder and up there are a number of full length luff extrusions (L=2400 mm) and finally there is a top extrusion that has to be cut to length to suite the actual forestay length.
  • Page 10 To find out the cutting length of the top extrusion (D) and the length of the top distance tube (E), start with the length of the forestay wire (WL) that was calculated in table 1. Then follow the steps in table 2 below. On fixed length forestays (incl. rod stays), verify WL by measuring the stay length from centre of eye to end of stud (wire) or end of rod head.

  • Page 11: Assembly 3.1. Luff Assembly

    Assembly At this point the top luff section and the top distance tube should be cut to length according to table 2. 3.1 Luff assembly Luff assembly should be carried out on a clean, flat surface. Make sure there is enough space for the entire forestay length to be stretched out.
  • Page 12 9. Repeat for the remaining 2400 mm luff extrusions. Use short joining sleeves only. (94 1/2”) 10. Fit the long joining sleeve onto the wire with two-hole end downwards. Then fit the 1000 mm (39 3/8”) luff extrusion with two-hole end downwards. Fit the long connecting plate to the 1000 mm (39 3/8”) extrusion and push the joining sleeve upwards to hold it in position.

  • Page 13: Fitting Sta-Lok Wire Terminal

    3.2 Fitting Sta-lok eye terminal Note! For systems with swaged stud terminal, skip this part and go directly to 3.3. Before cutting the wire, measure the wire from the centre of the hole in the top swaged eye terminal. Mark the measurement WL carefully on the wire using a marker pen.
  • Page 14 Space the outer strands of the wire evenly around the wedge and bring down the socket so that the strands are held in place. Hold an adjustable spanner between the 1000 mm (39 3/8”) extrusion and the socket. Tapping the core of the wire, locate it firmly in the socket. Check that the core of the wire protrudes approx.

    3.3 Fitting eye terminal to swaged stud (Stud/Eye) 1. Remove the toggle from the eye fitting. Fig. 3.3.a 2. Screw the eye terminal part onto the stud terminal until the holes in stud and eye align. Fig. 3.3.b 3. Fit the spirol spring pin using a hammer to permanently lock the terminal. Fig.

  • Page 17: Drum Unit Assembly

    4. Turn the drum unit so that the small knob in the upper hub is oriented as shown in relation to the luff extrusion. The knob should be pointing in the same direction as the foil to fit correctly into the forward adaptor half.

  • Page 18: Installation

    4 Installation Installation of the Furlex system on the boat requires a minimum of two persons, however it is recommended to be at least three persons to do the job more easily. 4.1 Mast attachment The guiding principle for fitting the Furlex to the mast is that the forestay connection should allow sufficient articulation in all directions.

  • Page 19: Deck Attachment

    4.2 Deck attachment The lower end of the Furlex-system comes with a fork toggle as Fig. 4.2 standard. This can normally be attached directly to the boat’s forestay fitting at the stemhead. Check that the drum unit does not interfere with the pulpit, navigation lights or other deck fittings. If the boat is fitted with a bow anchor, it may be necessary to permanently raise the drum unit to give the crew sufficient space for anchor work.

  • Page 20: Installation On A Stepped Mast

    4.3 Installation on a stepped mast 1. Slacken the backstay as much as possible, but do not remove it. 2. Pull the mast forward using a genoa halyard or a spinnaker halyard. Secure the halyard to a strong deck fitting using a screw pin shackle or tie the halyard to a strong deck fitting. For safety reasons, do not use snap shackles.
  • Page 21 4.5.2 Fitting the furling line If the sail’s ultraviolet (UV) protection is fitted on the starboard side of the sail, the furling line should exit on the port side of the line drum. If the UV protection is fitted on the port side, the furling line should exit on the starboard side of the line drum.

  • Page 22: Adjusting The Forestay Length

    4.6 Adjusting the forestay length The Furlex system may be supplied with or without an integrated rigging screw. 4.6.1 Furlex with rigging screw With an integral rigging screw, the forestay length can be easily adjusted. Tensioning the forestay however, is done by tensioning the cap shrouds and/or the backstay, and not by tensioning the forestay rigging screw.

  • Page 23: Checklist

    4.6.2 Furlex without rigging screw On Furlex-systems without an integrated rigging screw, the forestay length can be increased by fitting extra toggles. These can be fitted at the upper or lower end of the forestay wire. To shorten the Furlex-system, the forestay wire and the luff extrusion must be cut. See chapter ”Dismantling”...

  • Page 24: Operation

    5 Operation Before hoisting the sail, make sure to tension backstay and/or runners so that the forestay is fully tensioned for hard, close-reach sailing. If the sail should be hoisted and firmly tensioned before the forestay is fully tensioned, excess strain is put on the halyard, the halyard swivel and the sail when the forestay is tensioned.

  • Page 25: Unfurling The Sail

    5.2 Unfurling the sail 1. Release the furling line and the windward genoa sheet. Allow these to run freely while the sail is being unfurled. 2. For a controlled unfurling manoeuvre, it is best to place a turn of the furling line around a winch or a half- turn around a cleat.

  • Page 26: Reefing

    5.4 Reefing Furlex is provided with a tack attachment which rotates in relation to the luff extrusion. When furling and simultaneously applying a limited countertension in the sheet, the luff extrusion makes approximately one revolution before the tack fitting starts rotating as well. The part of the sail with the biggest draft will in this way be flattened.

  • Page 27: Inspection

    6 Maintenance 6.1 Inspection To ensure that the system rotates easily and functions satisfactorily year after year, regular inspection and maintenance should be carried out once a year. Maintenance is simple, even with the Furlex rigged on the boat. Inspection points: •...

  • Page 28: Dismantling

    6.4 Dismantling Never take the halyard swivel or the drum unit apart as you will find it difficult to re-assemble them correctly. (The ball bearings are loose and difficult to refit!). Contact your Furlex dealer if service is required. 6.4.1 Sail feeder Fig.
