Ronstan Series 160 Furler — User Manual & Spec Sheet

Furler System

  • Designed for sails with a "straight" luff (code zeros, screechers, staysails), generally sailed at true wind angles less than 90°.
  • The tack attaches to the furler, the head to the top swivel; the sail furls around the luff cable along its whole length.
  • The sail must be either completely unfurled or completely furled – no partial furling.
  • You need a synthetic luff cable (torsion line) with a thimble at each end, between the furler fork and the top swivel. Discuss type, diameter and length with your sailmaker.

Setup

  • Torsion rope with a thimble at each end
  • Top swivel (head)
  • Furler with continuous furling line
  • Attachment to the bow fitting: shackle, snap shackle or 2:1 fairlead

Furling Line & Guide Arm

Continuous Furling Line

  • The Series 160 furler is optimised for 10mm (3/8") rope.
  • Load or remove the line without unreeving it from the cockpit blocks: rotate the drum to align the slot in the drum bottom plate with the guide opening.
  1. Push the rope through the guide opening and deep into the slot until it is in the hole.
  2. Rotate the drum all the way round until the slot lines up with the guide opening on the other side of the guide.
  3. Pull the rope out through the guide opening.
  • Align the furling line correctly with the guide; use blocks or fairleads where needed.
  • The furling line can be cleated to keep the sail from unfurling.

Guide Arm Alignment

  • The guide arm can be set in-line or at 90° to suit the deck or bowsprit attachment.
  1. Remove the screw 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. Refit the guide arm to the shaft with the same screw.

Accessories & Spares

  • Top swivel: top half of the system, matched to the furler load rating; fork designed for the torsion line thimble; maintenance-free factory sealed bearing, retained clevis pin and low profile shackle pin head.
  • Snap-shackle adaptor: replaces the shackle on the furler or top swivel for quick attachment to the bow fitting or halyard.
  • 2:1 fairlead: replaces the shackle on the furler. The tack line is dead-ended at the deck or bowsprit end, runs up round the fairlead, down to a block and aft to a rope clutch – a popular way to adjust torsion rope (and luff) tension.
  • Thimble: terminates the torsion rope at both ends (wrap the rope round it and stitch or splice). Its extra hole takes the tack lashing; lashing the sail to the thimble rather than the furler lets the torsion line and sail be removed easily.
  • HR shackle: replacement shackles for both the top swivel and the furler.
  • Quick release pins: ball-lock pins with lanyard that replace the clevis pins in the top swivel and furler, for fast attachment and removal of the torsion line (e.g. swapping sails between upwind and downwind legs).
  • Rotation stop: Engage once the sail is fully furled to stop it unfurling if the furling line is un-cleated (sail left hoisted, or lowered to bag it). Screws into the threaded hole in the guide arm; a spring-loaded plunger pin drops into one of the drum through-holes. Operate it at the furler or remotely with a trigger line to a cleat; add a short length of shock cord to the trigger line to keep the pin disengaged as the furler moves with the boat. Designed to fail under high furling line load to protect the furler – simply replace it.

Maintenance

  • Rinse regularly with fresh water to remove salt.

  • 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 a Ronstan re-seller.
  • Furlers carry a three year warranty (Ronstan terms and conditions).
