Furlable downwind sails offer a powerful and enjoyable sailing experience—whether you’re cruising or racing, on small boats or large yachts.

This is the basic kit for a CXr15 Code 0 furler and it includes the lower furling unit and the halyard swivel. 

In addition, you need an ø8 mm endless furling line which is available in various lengths. You need a sail of Code 0 type with an ø11 mm AT-cable integrated in the luff and fitted with terminations for CXr15. 

Extra accessories you may want is a 2:1 purchase system for the halyard and fairleads to guide your furling back to the cockpit in a organized fashion. 

CXr is sold by our global network of sailmakers who are delivering the complete Code 0 experience including the sail, the hardware and the installation. 

CXr – “r” for Ratchet.

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 feature when the drum is spinning freely. The fork—compatible with a thimble, tack swivel adapter, or the Seldén Nail terminal—is  equipped with a spring-loaded lock.  The pin is captive, ensuring it cannot be lost overboard. All structural components are manufactured from high-strength Duplex steel and machined aluminium. The drum features sealed steel bearings for long service life and minimal maintenance.

The Seldén ratchet

The concept behind the ratcheting drum is twofold: to prevent unintentional unfurling during hoisting, and to make furling the sail significantly less exhausting.

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:

• If you want the drum to spin clockwise, pull the line from the starboard side of the drum.

• If you want it to spin counterclockwise, pull from the portside.

The halyard swivel

The swivel features the same spring-loaded lock and captive pin as the furling unit, ensuring secure and reliable connections. It is equipped with a sealed steel bearing for long  service life, and a rubber fender is integrated to  protect the mast from damage in case of contact.
