Selden Furlex 204TD & 304TD — Owner's Manual

Main Dimensions (mm)

Drum below deck, tack at deck level. Lower terminal options: Sta-Lok eye (standard), Sta-Lok rigging screw (stroke 60 mm on 204TD, 80 mm on 304TD, integrated in the torque tube) or swaged stud. Wire stays are 1x19; options 2 and 3 also suit rod and compact (Dyform) wire – rod stays need supplement 597-180-E. For genoas with large LP, the S-series line drum and line guide can be used if the TD drum takes too little line (needs more room below deck).

• C is nominal: deck thickness there should not exceed 17 mm (204TD) / 25 mm (304TD); thicker decks need a cavity to clear the top forward drum edge. Seal sandwich cores.
• D is fine-tuned with the adjustable fork terminal; for larger gaps use a custom stainless bar or rod stay (short wire pendants not recommended). Pin "E" must be fixed in all directions.
• Forestay-to-deck angle between 70,5° and 75,5°; otherwise fit spacers under the deck fitting.
• Deck hole: hole saw Ø108 (204TD) / Ø127 (304TD), screw holes Ø6,5; 1:1 template included.

Sail Measurements

• Max. luff length = FLD – (F + E).
• Halyard-to-forestay angle 10–15°, never less than 10° (section 6.1 of the manual says 5–10°, as printed); at least 50 mm between halyard swivel and top guard.
• Webbing loops at head and tack; HMPE or wire pendant at the head if the sail is short.

Forestay Wire & Luff Extrusion Length

FLD = FL + CH (chainplate hole to deck, along the forestay); NFL = FLD – TDH (204TD: 125mm, 304TD: 145mm); WL = NFL – T.

• N = (WL – (A+B)) / 2400, rounded down; C = N × 2400; top extrusion D = WL – (A+B) – C; top distance tube E = D – X (204TD: 200mm, 304TD: 250mm).
• Example (304TD 10mm, rigging screw 50% extended): FL 16070 + CH 40 = FLD 16110; – 145 = 15965; – T 150 = WL 15815; (15815 – 1025) / 2400 = 6.16 → N = 6; C = 14400; D = 390; E = 140.
• If D is under 400 mm: N new = N – 1, C new = N new × 2400 + 2000, D new = D + 400, E new = E + 400 (example: 14000 / 790 / 540). If D exceeds 2000 mm, cut the top from a 2400 mm extrusion.
• Foil: 730 mm (204TD) / 700 mm (304TD) bottom extrusion, 2400 mm extrusions and a 2000 mm top. Short joining sleeves 204TD 200mm / 304TD 250mm; long sleeve 260mm / 325mm. Assemble on the stay from the top down; bottom distance tube in about 50 mm (2"), bearing halves secured with the spring pin.
• Torque tube alignment mark on the luff section: 204TD 45mm, 304TD 52mm. Sta-Lok: wire core protrudes approx. 2 mm; compact wire needs the compact wedge supplied with the compact wire pack.

Inspection, Service & Storage

• Yearly: check the foil, that everything turns freely and bearings are greased; grease all four ball bearings in the lower bearing assembly (upper and lower main bearings, tack ring bearings) and both halyard swivel bearings with water-resistant grease.
• Halyard leads: inspect yearly, replace at 50% wear.
• Wash with fresh water and mild detergent, rinse well; silicone-free polish or wax on the extrusions. Store with the mast, aluminium away from steel, never damp in plastic; in frost areas store dry or with centre extrusions raised.
• Never dismantle the halyard swivel or drum unit. Re-making a Sta-Lok: heat the threads, at least 10 mm of free wire above the socket in the vice, cut strands about 5 mm, use a new wedge.
