Page 7: Calculations
Calculations 1. Determine mast rake with fore and backstays tensioned. 2. Slacken off the backstay as much as possible. Use the genoa halyard to pull the masthead forward. Tie the halyard to the boat, do not use the snap-shackle. Remove the forestay without altering the setting of the rigging screw if fitted. -

Page 9: Installation
Installation Forestay installation to deck 1. The forestay is fitted with a stout torsion-resistant lower toggle (see fig. 9.2). This is attached to the stem-head fitting. The toggle can be fitted either athwardships or fore-and-aft. 2. Check that the stem-head fitting and the toggle are suited (see table below). The stem-head fitting must be able to withstand a torque of 330 Nm for 300 H, or 725 Nm for 400 H. -
Page 10: Forestay Attachment - Guiding Principle
Forestay attachment - guiding principle Mast attachment Some Seldén forestay attachment options are shown below, illustrating the rules and exceptions. 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. Fig. -
Page 11: Hydraulic Motor
Installation Hydraulic motor … The drive unit and hydraulic motor are tested before delivery. … The hydraulic motor is a Danfoss OML 12,5 cm3/revolution or a OML 20 cm3/revolution. Maximum recommended pressure (p): 140 bar. … The oil flow (Q) gives at 10 litres/min (OML 12,5) or 20 litres/min (OML 20) a nominal speed (n) of 40 rpm. -
Page 12: Hydraulic Hoses
Hydraulic hoses 1. Hydraulic hoses for installation below deck are not supplied. (See fig. 12.1) 2. Connecting threads are G 3/8. (See fig. 11.1) 3. Use hydraulic hoses of good quality corresponding to SAE 100R/-ISO3949. Minimum dimension 3/8”. Minimum working pressure 140 bar. Minimum recommended bending radius 150 mm (6”).

Page 14: Assembly Of The Furlex-System
Assembly of the Furlex system Assembly of the luff section, 300 H Assembly should be carried out on a horizontal surface. Connect the luff extrusions one by one as follows: Fig. 14.1 The long joining sleeve must be in the 1000 mm (39 3/8”) luff extrusion when commencing assembly. - Page 15 Fig. 15.1 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. Check that the dis- tance (J) between the end of the distance tube and the end of the extrusion is approximately half the length of a joining sleeve.

Assembly of the Furlex system Assembly of the luff section, 400 H Assembly should be carried out on a horizontal surface. Connect the luff extrusions one by one as follows: Fig. 16.1 Fit the long joining sleeve at the same time as the long connecting plate into a 2400 mm (94 1/2”) luff extrusion and guide the sail feeder on. - Page 17 Fig. 17.1 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. Check that the dis- tance (J) between the end of the distance tube and the end of the extrusion is approximately half the length of a joining sleeve.

Page 18: Forestay Wire
Forestay wire 1. Chamfer the wire end slightly with a file. 2. Thread the wire through from the top. Should the wire snag inside the extrusions twist it anticlock- wise past the obstruction. 3. Apply tape tightly to both sides of the cutting mark and cut the wire. 4. - Page 19 Fig. 19.1 Terminal F Former Place the former in the Terminal F piece and screw the terminal together so that the strands beco- me formed between the wedge and the former. Avoid damaging the surface of the female terminal piece with your spanner. Fig.

Page 21: The Drive Unit
The drive unit Push down the drive unit. Join it to the lower toggle with the clevis pin. The luff extrusion is fastened to the drive unit with two stop screws. Be careful to see that the stop screws are correctly sited in the pre-drilled holes in the extrusion. -
Page 22: Halyard Leads
Halyard leads When the sail is furled on a rotating luff extrusion the halyard is also inclined to twist around the extrusion because of internal friction in the swivel. If this should occur furling will stop and may cause damage. To prevent this from happening the halyard should be angled at least 10°... -
Page 23: Fitting The Halyard Leads
Fitting the halyard leads 1. Determine location of the leads 2. Using the adhesive insulation pads as templates, drill the fixing holes with the 5.2 mm drill bit supplied. 3. Fit the leads over the halyards as it is not possible to thread them through afterwards because of the shackles. -
Page 24: Adjusting Forestay Length
Adjusting forestay length Adjustment is 100 mm on the 300 H rigging screw, and 110 mm on 400 H. 1. Take out the stop screws holding the luff extrusion. (See fig. 21.1) 2. Undo the hydraulic hoses from the quick coupling. 3. -
Page 25: Operation
Operation Unfurling the sail Haul in on the sheet while pressing the unfurling switch. By doing this, the sail will not flap and be subjected to excessive wear. Stop the reefing gear when the sail is fully open and the luff extrusion has a suitable angle to the apparent wind. -
Page 26: Manual Operation
Manual operation A standard winch handle can be used in the event of loss of oil pressure or current. The by-pass valve is located on the through-deck fitting (see fig. 11.1). Warning sign Switch the by-pass valve over to ”Winch handle” Thereafter, put the winch handle in the socket. -
Page 27: Maintenance
Maintenance Periodic examination and maintenance of the system is necessary if it is to operate easily and give long service. Give it a thorough examination on a regular basis. Follow the schedule below. Cleaning Wash and rinse the entire Furlex system with fresh water to remove dirt and salt. This is especially important with the lower parts of the unit, and in particular the tack swivel, as these are most exposed to salt water. -
Page 28: Dismantling
Dismantling The drive unit With forestay off the mast The entire drive unit is dismantled by pushing it upwards over the luff extrusion, see fig 21.1. The sail feeder, halyard swivel, and top guard must first be removed from the extrusion. With forestay rigged Note! This is a simple operation with forestay wires of Ø... -

Jaw pads (Aluminium) Heavy vice Terminal F Tube mandrel Fig. 29.1 Terminal M 6. Hold the wire between two aluminium pads in a heavy vice (see fig. 29.1). Protect the threaded stud with a mandrel, and give it a sharp hit with a heavy (appr. 1,5 kg/3 1/2 lbs) hammer. (See arrow.) The wire should then free itself from its conical seat in the male terminal piece. -
Page 30: The Hydraulic Motor
The Hydraulic Motor The hydraulic motor should only be removed from the drive unit if it is not possible to turn the winch handle (see Manual Operation, page 26), or if the motor has to be replaced. The most likely reason for this would be that there are impurities in the oil. -
Page 31: The Sail
The sail The sail should be made for rolling up on the starboard side of the luff foil. Any sun-strip should therefore be on the starboard side of the sail. A high cut clew can give a constant sheet angle even when reefing. -
Page 32: Important Points To Remember Before Sailing
Important points to remember before sailing … The sail rolls on to the starboard side of the luff extrusion. … The halyard angles out 5–10° from the forestay with sail set. … All sails used have the right total luff length. See page 31. …...
