The CDI Flexible Furler FF2 is a marine device designed for furling sails on sailboats. It aims to simplify sail handling by allowing the sail to be rolled up or unfurled from the cockpit. The system is designed for easy installation and maintenance, with specific instructions provided to ensure proper and safe operation.
The Flexible Furler FF2 system allows a jib or genoa to be furled (rolled up) around the headstay, eliminating the need to drop and bag the sail. It consists of a luff extrusion (foil) that encases the headstay, a furling drum/spool at the bottom, and a halyard top fitting at the top. A furling line, wrapped around the drum, is pulled to rotate the luff extrusion and furl the sail. The internal halyard system allows the sail to be hoisted and tensioned within the luff extrusion.
Installation: The installation process involves several steps, starting with uncoiling and straightening the luff extrusion. The luff is shipped coiled and must be uncoiled carefully to avoid damage and kinks. Straightening involves recoiling the luff in the opposite direction and allowing it to rest for at least 3 hours. Warmer temperatures can speed up this process.
Assembly begins by measuring the headstay length and cutting the luff extrusion to the correct size, deducting 13 inches for the halyard top fitting. The halyard is then threaded through the top fitting and the luff extrusion. The halyard top fitting is attached to the luff with a set screw.
The turnbuckle is unscrewed, and the headstay is passed through the halyard top fitting and luff. The turnbuckle body is then screwed onto the threaded pin. Additional washers and an anti-rotation strap are added to the T-bolt, which is then placed through the bottom of the cup, followed by the bearing. The cup and anti-rotation strap are aligned and screwed together.
The furling drum/spool is slid onto the luff, aligning the sail-feed slot with the anchor shackle. The luff support pin is inserted into the spool. The mast is then stepped (if down) and the headstay attached. The backstay and headstay tension are adjusted.
A furling line is tied to the spool, and the spool is manually rotated 20 times to load the line. The furling line should be wrapped counter-clockwise for starboard exit or clockwise for port exit. Fairleads and a cleat are installed for the furling line.
Sail Hoisting and Furling: To hoist the sail, a messenger line is attached to the de-cored end of the halyard. The halyard is pulled until the ferrule reaches the top of the forestay. The halyard length is then trimmed based on whether the sail is full hoist or not. The halyard is attached to the head of the sail using a shackle or knot.
The luff of the sail is fed into the sail-feed slot while hoisting the sail by pulling on the messenger line. Once fully hoisted, the messenger line is removed, and the halyard is tied off on the anchor shackle on the spool. The sail is tensioned by tightening the tack tension line to the second shackle on the spool and pulling the halyard at a vertical angle.
To furl the sail, the furling line is pulled while maintaining tension on the jib sheet. When sailing reefed, the jib leads should be moved forward to maintain proper sail shape and prevent the furler from rising off the bearing.
Rigging Considerations: The furler system must not be mounted above the turnbuckle to prevent unscrewing and dismasting. Link plates can be used if more clearance is needed. Cotter pins should be used to lock the turnbuckle, not locknuts. Toggles are required at the bottom of the headstay, and a toggle is recommended at the top.
General Maintenance: The only required maintenance is to rinse the furler system, including the ball-bearing assembly, with fresh water 1-2 times per year. This helps clear out any accumulated salt or dirt. Lubricants are not required, but Teflon sprays or dry lubricants are acceptable on the luff if needed.
Storage: For storage, the furler should be strapped to the mast in a horizontal position, with the end supported by a 2x4 or PVC tube. It is important to keep the extrusion as straight as possible, avoiding any sagging or twisting. Sharp bends in the extrusion should be avoided as they can become permanent and are not covered under warranty. It is not necessary to remove or recoil the extrusion for storage, and doing so over long periods is not recommended as the furler ages. The furler should not be exposed to temperatures above 140°F/60°C.
Warranty Exclusions: The 10-year limited warranty does not cover damage incurred from weather, trailering or transporting, collisions at sea, improper storage, improper uncoiling or straightening of the luff (including using weights or heat guns), etc.
