Product Overview

Gen 2 Furlers feature a continuous line installation and removal system that requires neither tools nor disassembly. It allows easy sail and furler removal, leaving the continuous line and its associated lead blocks and cleats in place on deck. The system also fits systems where the continuous line cannot be removed from the boat, such as when it is routed through underdeck channels or under line covering panels.

Drums incorporate a sophisticated furling line groove profile and cross hold geometry to grip the furling line securely when furling.  This is the same technology developed first by Ronstan for use in their ratchet blocks to grip line gently but securely.  When deploying the flying sail, the continuous furling line self-ejects from the grip zone, remaining stationary for smoother, safer operation with minimum rope wear.  A floating PTFE perimeter strip ensures the unloaded furling line can't fall from the drum or become snagged.

Dedicated Top-Down models for soft luff sails

Top-down furling provides a new level of simplicity, safety and speed for handling of soft luff sails such as asymmetric spinnakers and gennakers. Cruisers can store, deploy and retrieve these sails as simply as they would a furling headsail from the safety and convenience of the cockpit. Racers too can benefit from the characteristics of top-down to allow super-fast retrieval of code zeros by pre-winding the torsion rope and firing the sheet when ready. Top-down furler set includes furler, top swivel and shackles.

Secure, snag-free connections: Furlers and top swivels have captive quick release clevis pins.

Maintenance-free bearing system: Furlers and top swivels feature a factory sealed, maintenance-free bearing. Roller bearing sets run on hardened races for smooth high-load performance.

Material selection for strength and durability: Hard anodized grade 6061 T6 aluminum construction provides durability and corrosion protection. Grade 2205 stainless steel is utilized for the load-bearing shaft for optimum strength to weight ratio.

Multiple attachment options: Attachment options include high-resistance shackles, snap shackles, fairleads and quick-release pins, as well as hard anodized aluminium thimbles designed specifically to suit the user-supplied anti-torsion luff line. The furler drum fits either 0° or 90° attachment, as required to match the take-off alignment and deck layout.

Rotation stop accessory

A compact rotation stop can be added to compatible models of furlers to prevent inadvertent unfurling of the sai. The rotation stop is installed on the underside of the furler and can be locked out when in use or when the sail is furled or stowed.
