Asymmetrical Spinnaker - Furler Package

WANT TO SEE YOUR CREW SMILE?

The power and acceleration achieved when unfurling a Code 0 or an asymmetric spinnaker is spectacular and makes sailing more enjoyable.

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.

ASYMMETRICAL SPINNAKER

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 160°.

SELDÉN GX, FOR TOP-DOWN FURLING OF AN ASYMMETRICAL SPINNAKER/GENNAKER

Seldén GX drum and halyard swivel and an AT-cable is included in the kit. We also provide an endless spliced furling line made to any custom length and dual removable stanchion leads.

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. Lead the furling line to the cockpit by using Seldén Double Fairleads on the stanchions, tighten the furling line and secure it in the Twin-Cam block (sold separately if required. Thereafter hoist the furled sail.

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 AT-CABLES (ANTI-TORSION)

The more torsional rigid AT-cable, the quicker and safer the sail will furl. Seldén provide the most rigid cable on the market, three times more rigid than the second best, and it is included in the Seldén GX kit.

DOUBLE FAIRLEAD

Ordinary blocks cannot be used to lead the endless furling line back to the cockpit. Seldén Double Fairlead consist of a composite bracket fitted to a 25 mm or 30 mm stanchion and a spring loaded ”push-and- twist” bracket in stainless steel. Easy to open to attach the line and just as easy to close. The Double Fairlead prevents the line to get tangled up and the smooth stainless bracket prevents friction.
