– A new generation of Code 0 / Top-Down furling systems

Furlable Downwind Sails – Power, Performance and Control Furlable downwind sails offer a powerful and enjoyable sailing experience—whether you’re cruising or racing, on small boats or large yachts. The furling system serves as the vital link between the sailor and the sail, delivering both convenience and safety. For the cruising sailor, it means being able to handle a large Code 0 or gennaker from the comfort of the cockpit. For the performance-oriented crew, it offers the flexibility to quickly switch between different headsails. All sailors benefit from the ease of dousing and stowing the...

Jib 0 The Jib 0 is an alternative to a light-wind jib and provides good upwind performance in winds up to approximately 6 knots. It is used from close-hauled until the wind angle opens enough to switch to a gennaker or spinnaker. The Jib 0 can advantageously be combined with a staysail for an optimal sail setup. Seldén CXr is the right furler for this sail. A Code 0 with a special designed load-bearing luff instead of an ATcable. Seldén provide tack-boards and head-board to fit CXr furling unit and halyard swivel, ensuring a perfect match for this type of sail. Mid girth <75% of foot length The...

Asymmetric spinnaker Mid girth >75% of foot length This sail is often called “gennaker” or “cruising chute”. When the mid girth is >75% of the foot length, the sail is defined as a spinnaker in most international measurement rules. The luff is at least 2% longer than the leech and this is what makes the sail asymmetric. This sail is furled with a Seldén CXr system with a Tack Swivel Adaptor providing a swivelling tack attachment for Top-down furling. An AT-cable connects the Tack Swivel Adapter to the halyard swivel and transmits the rotation of the drum enabling the furling to start at the top...

A new generation of downwind furlers - loaded with new features Seldén introduces the second generation of downwind furlers —the CXr—building on the success of our popular CX and GX furlers, now enhanced with several new features. CXr – “r” for Ratchet. The furling unit The use of composite materials ensures low weight, while the metal “teeth” of the line driver provide a secure, high-strength grip. The drum cover is impact-resistant, and the line guide is made from cast, highly polished stainless steel—smooth and rounded for minimal friction. A wedge separates the furling line, an important...

The Seldén ratchet For Seldén, ease of use and reliability are key—and this patented design delivers both. The concept behind the ratcheting drum is twofold: to prevent unintentional unfurling during hoisting, and to make furling the sail significantly less exhausting. How to use Seldén’s ratchet function Before unfurling, the ratchet mechanism preventing the sail from unfurling unintentionally, must be unlocked. To do this, make a short and distinct pull on the furling line in the same direction as the direction you want the drum to spin. Imagine you’re looking at the drum head-on from aft:...

Selden’s Nail Terminal is a solution for Anti-Torsion cables, developed to enable quick, safe, and reliable assembly of Code 0 furling systems. Machined from anodized aluminium, the terminal features a female fitting into which the AT-cable is inserted. Sharp, hardened stainless steel nails are then driven through the terminal and the AT-cable—either with a vise or by hammering-securing the assembly in place. Thanks to the use of specially designed nails, the Dyneema® fibers in the cable remain undamaged, ensuring that the load-bearing capability and torsional rigidity of the AT-cable is fully...

There are two versions of Tack Swivels, each designed to accommodate different terminations of the AT-cable. Slide the Tack Swivel on to the Nail terminal and secure with one screw Tack Swivel Adaptor - Fork/Eye For thimble, Nail terminal or tackboard

Code 0 halyard with 2:1 purchase To boost the performance when using a Code 0, the halyard load must be higher than what normal halyard boxes and stoppers can handle. Therefore, a 2:1 purchase needs to be arranged by fixing the dead end of the halyard in the mast and letting it run through a block attached to the halyard swivel. Position on the mast must be specified by Selden. In most cases Code 0 sails need to be hoisted lower than gennakers and spinnakers. ART. NO. DIM.
