Seldén GX Furler


The Seldén GX is a furling system for asymmetric spinnakers and cruising chutes. This Top-down-furling makes crusing fun and enjoyable for everyone aboard. The Seldén GX consists of a line driver and a halyard swivel connected by an anti-torsion line. When turning the drum the anti-torsion line makes the top of the sail furl first, while the tack is independent on a swivel. At the end of the day the furled sail is a neat, tight roll which is simple to bag and stows easily.

Prices for specific GX models are listed in the drop-down menu and will vary depending on Sail Area.

The formula used to estimate sail area is:  J x 1.8 x I x .85= ~ Asymmetric Spinnaker Sail area.

I = Deck to mast length – distance from the deck to the intersection of the forestay and and mast.
J = Forestay to mast length – distance from the forestay at the deck to the mast at the deck.



Tandem Block for Furling Line

Double Fairlead

SKU: Selden GX Furler - Configurable. Categories: , .

Seldén GX Furler. As opposed to the popular Seldén CX furler, the GX is featuring a free tack swivel and will furl the downwind sail from the top down. The concept of Top-down-furling means that the sail starts to furl around a torsion-line at the top and the tack will not furl until the fullest part of the sail is doused. To keep the installer happy, Seldén has developed a unique and patented line lock for the anti-torsion line. No splicing needed, all you need is simple hand tools. If your racing now or thinking about racing this is the perfect furler. Combine with your regular spinnaker and without penalty within the ORCi and IRC rules. Tandem blocks are reccomended to be placed Mid-Ship. However, furling and unfurling can be done from the cock pit. Additional equipment needed: PBB Shackle 50 double and Snap Shackle Adaptor 50. Returns must be made within 45 days of original ship date and a 20% restocking fee will be charged for all returns.

    last spring i purchased a Catalina 275. it came with a seldon top down furler. I often sail single handed, and like to push my limits. I feel much more comfortable using my spin when I know I can douse it at will, from the cockpit. Very easy to deploy and furl in. It makes sailing more fun by allowing me to use my spin more often. I have used sock/tube dousing systems on my previous boat and would gladly pay the extra cost for the safety and convenience of staying in the cockpit and still enjoying my spin!
