Want to see your crew smile?

 

The power and acceleration achieved when unfurling a Code 0 or an asymmetric spinnaker is spectacular. It will make your sailing more fun. Simply hoist the furled sail, release the furling line, pull on the sheet and you have added horse power to your sailing and given your crew a positive sailing experience. To douse the sail, ease the sheet, pull the continuous furling line and secure it in the purpose made Twin Cam block. Once the sail is furled it can be neatly dropped and coiled into a bag or left hoisted for later use. Seldén provide all necessary accessories for safe and carefree furling of “off-the-wind” sails.

 

The sails

 

czsail.pngCode 0 (Zero)

 

The Volvo Ocean Race was the break through for the Code 0 concept, but lately the benefits of this type of sail have become recognized and appreciated also amongst ordinary sailors for the extra power it brings to light wind sailing. The luff is straight, set under tension and made for furling which simplifies the handling of this large sail. An AT-cable is integrated in the luff and fitted with thimbles in head and tack, and the entire luff length is furled simultaneously. The Code 0 is hoisted as high as the mast dimension permits and is tacked to the bow or to a sturdy bowsprit. The design is quite flat and reaches its maximum performance in apparent wind angles between 40° and 90°. Seldén CX is the right furler for this sail.

This sail is often called “gennaker” or “cruising chute”. The mid girth is >75% of the foot length and 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 GX system and fitted at the tack to the swiveling tack attachment and at the head to the halyard swivel. An AT-cable connects the drum and the halyard swivel and transmits the rotation of the drum enabling the furling to start at
the top and work its way down until the entire sail is stowed away. This is called top-down furling. The Seldén GX furler is fitted to the bow of the boat or preferably on a retractable Seldén bow sprit to expose the sail to the wind and to get clearance from the forestay. The halyard tension is moderate and the sail is hoisted using the spinnaker halyard. This sail performs at its best in apparent wind angles between 70° and 110°.

The furlers

 

Seldén CX and Seldén GX are operated with an endless furling line running over a line driver drum. The furling line is preferably led all the way back to the cock pit and Seldén offer the Double Fairlead and the Twin-Cam block for a well organized set up. A purpose made AT-Cable has been developed to secure the function of the system and as the performance of top-down furling is dependant on the torsional rigidity of the AT-cable, it is included in the Seldén GX furlers.

  • Metal ”teeth” in the drum make for a good grip on the line when furling the sail.
  • A wedge in the line guide separates the line from the drum when unfurling the sail and the drum spins freely.
  • Sealed steel bearing in the drum and in the halyard swivel for long service life.
  • Rubber fender prevents the halyard swivel from chafing the mast while hoisting the furled sail.
  • CX. Spring loaded lock makes it easy to connect the thimbles to the drum and the halyard swivel.
  • GX. Patented line lock for easy mounting of the AT-Cable to the drum and to the halyard swivel.
  • All structural parts are made of high-strength Duplex stainless steel. This means reduced material and low weight.
  • Non-structural parts are made of impact resistant glass fibre reinforced polyamide composite.

Seldén GX, for top-down furling of an asymmetric spinnaker/gennaker

 

Seldén GX drum and halyard swivel and an AT-cable is included in the kit. The drum and the halyard swivel are permantly fitted to the sail with the Seldén line lock. Connect the drum to the bow and the spinnaker halyard to the halyard swivel.

Selden CX, for Code 0

 

cx10.png

The AT-cable is integrated in the luff of the sail and thimbles connect the luff to the drum and to the halyard swivel. Special Cable clamps are required to fit the thimbles to the Seldén AT-cable. A dedicated halyard for Code 0 is required and 2:1 purchase is recommended to obtain the required luff tension and to reduce the load on the halyard sheave and on the line stoppers. The drum and the furling line can be permanently mounted to the bow and along the stanchions. Order Here...

Seldén CX, for top-down furling of an asymmetric spinnaker/gennaker

 

This is an alternative to GX allowing the drum and the furling line to be mounted permanently. Snap in the furled gennaker and hoist it using the spinnaker/gennaker halyard.

 

A Seldén CX drum is combined with a Tack Adapter and a GX halyard swivel, both of them with Seldén line lock. The furled sail with the Adapter is connected to the drum and the sail is hoisted with the spinnaker halyard. The drum and the furling line can be permanently mounted to the bow and along the stanchions.

Seldén CX, for Code 0 & top-down furling of an asymmetric spinnaker/gennaker

 

This is an alternative to GX allowing the drum and the furling line to be mounted permanently. Snap in the furled gennaker and hoist it using the spinnaker/gennaker halyard. This is an all-in-one solution for the sailor using both Code 0 and gennaker and prefers using one halyard for both applications.

 

A Seldén CX drum and halyard swivel for thimbles are used both for the Code 0 sail and an additional gennaker. Connect the sail suitable for the prevailing conditions to the drum and to the halyard swivel and hoist the furled sail using the Code 0 halyard. The Free Tack Adapter is permanently fitted to the tack of the asymmetric spinnaker/gennaker with the Seldén line lock. The drum and the furling line can be permanently mounted to the bow and along the stanchions.
