Selden GX 10 Top-Down Furling Kit - Three Length Options
For every sailor who is thrilled by boat speed in combination with fast and easy sail handling, the Selden GX 10 is an extra member of the crew. Unfurling an asymmetric spinnaker will give you instant gratification in terms of sailing performance and true sailing pleasure.
An Asymmetric spinnaker 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 Selden 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 Selden GX Furler is fitted to the bow of the boat, or preferably on a retractable Selden bowsprit, 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 power and acceleration achieved when unfurling an asymmetric spinnaker are spectacular. It will make your sailing more fun. Hoist the furled sail, release the furling line, pull on the sheet and you have added horsepower 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 an optional purpose-made Selden Twin Cam block. Once the sail is furled it can be neatly dropped and coiled into a bag or left hoisted for later use. Selden provides all the necessary accessories for safe and carefree furling of "off-the-wind" sails. Want to see your crew smile?
GX 10 Kit includes a Selden GX drum, halyard swivel, and an 11 mm AT-cable.
Three maximum overall system lengths are available; - 13 m (42')
- 16 m (52')
- 19 m (62')
The GX drum and the halyard swivel are permanently fitted to the sail with the included Selden line lock. Connect the drum to the bow and the spinnaker halyard to the halyard swivel. Lead the furling line to the cockpit using optional Selden Double Fairleads on the stanchions, tighten the furling line, and secure it in the Twin-Cam block. Now, hoist the furled sail. Selden GX Furlers are operated with an endless furling line running over a line driver drum. The furling line is preferably led back to the cockpit, and Selden offers optional Double Fairleads and a Twin-Cam block for a well organized set up. The purpose made 11 mm diameter AT-Cable has been developed to secure the functioning of the system, and since the performance of top-down furling is dependent on the torsional rigidity of the AT-cable, the more torsional rigid an AT-cable is, the quicker and safer the sail will furl. Selden provides the most rigid AT-cable on the market, three times more rigid than the second best, and it's included in the Selden GX kit. Features:
- 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.
- 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 fiber reinforced polyamide composite.
For Cruising In light winds you can have the furled sail hoisted, ready for action. Once you are off the wind, you release the furling line and pull on the sheet, and the asymmetric spinnaker unfurls while you remain in the safety of the cockpit. You can enjoy this type of sail from about 70° apparent wind angle, and when sailing dead downwind you pole it out to windward, preferably with a telescopic whisker pole. So, with a jib and an asymmetric spinnaker, your performance is optimized for all wind angles. At the end of the day, the furled sail is a neat, tight roll that is simple to bag and stows easily. For Racing An asymmetric spinnaker with a mid girth of minimum 75% of the foot length measures as a regular downwind sail. This means you can combine it with your regular spinnakers without penalty within the ORCi and IRC rules. Just imagine what difference this will make to your sailing performance in the borderland between jib and spinnaker. A real game-changer!
