Ronstan Series 80 Furler — User Manual & Spec Sheet

Furler System

Designed for sails with a "straight" luff (code zero, screecher, staysail), generally sailed at true wind angles below 90°. The tack attaches to the furler and the head to the top swivel, so the sail furls along the entire length of the luff.

  • Torsion rope
  • Continuous furling line
  • Top swivel
  • Thimble
  • Furler
  • Shackle, snap shackle or 2:1 fairlead
  • The sail must be either completely unfurled or completely furled: the furler cannot be used with a partially furled sail.
  • You need a synthetic luff cable (torsion line) with a thimble at each end, connected between the fork of the furler at the bottom and the swivel at the top. Ronstan recommends agreeing torsion line type, diameter and length with your sailmaker.
  • Furling line alignment matters: the line must lead fair into the guide. Use blocks or fairleads to guide it where required; the furling line can be cleated to keep the sail from unfurling.

Furling Line Installation & Removal

Optimised for 8mm (5/16") rope. The line loads and unloads without un-reeving it, for installations where it is permanently led aft through blocks or fairleads.

  1. Rotate the drum to align the slot in the bottom plate of the drum with the guide opening.
  2. Push the rope through the guide opening and deep into the slot until the rope is in the hole.
  3. Rotate the drum all the way around until the slot lines up with the guide opening on the other side of the guide.
  4. Pull the rope out through the guide opening.

Guide Arm Alignment

In-line or at 90 degrees to align the furler mount with the deck or bowsprit attachment.

  1. Remove the screw located in the guide arm underneath the drum.
  2. Rotate the guide arm and PTFE strip 90° until the hole in the guide arm lines up with the alternate hole in the shaft.
  3. Re-connect the guide arm to the shaft using the same screw.

Accessories

  • RS208010 Top Swivel – the top half of the system, matched to the furler load rating; fork designed for the dedicated torsion line thimble; maintenance free factory sealed bearing, retained clevis pin and snag-free low profile shackle pin head.
  • RS208020 Snap-Shackle – replaces the shackle on the furler or top swivel for quick attachment to the bow fitting or halyard.
  • RS208030 2:1 Fairlead – replaces the shackle on the furler for a 2:1 purchase: tack line dead-ended at the deck or bowsprit end, up around the fairlead, down to a block and aft to a rope clutch. A popular way to adjust torsion rope tension, and hence luff tension.
  • RS208040 Thimble – terminates the torsion rope at both ends (stitched or spliced); the extra hole is for lashing the sail. Lashing the sail to the thimble, not the furler, lets torsion line and sail come off the furler and top swivel easily.
  • RS208050 Shackle – replacement shackle for both top swivel and furler.

Maintenance

  • Rinse regularly with fresh water to remove salt.
  • Apply Ronstan RF3000 Sailfast™ (or a similar silicon based lubricant) over the body and components to enhance performance and prolong service life. Do not use petro-chemical lubricants.
  • Periodically remove fasteners and re-apply Tef-Gel® (TG-10) to prevent corrosion.
  • Factory sealed bearings are maintenance free. Bearing and seal replacement can be arranged through your local Ronstan re-seller.
  • Furlers carry a three year warranty (terms and conditions from Ronstan).
