This accessory for Seldén GX furlers enables the sailor to easily trim the luff of the gennaker. The Adjustable Tack Swivel slides up and down over the AT-cable and is handled from the cockpit with a down haul. As opposed to trimming the luff by slacking the halyard, the AT-cable can now be permanently tensioned and always ready for furling.

The sliding sleeve of ATS consists of two halves and therefore it is easy to retrofit the swivel on an AT-cable.

Selden Adjustable tack swivel for GX top down furler enables the tack height to be easily adjusted and so the luff tension can be adjusted at will.

The adjustable tack swivel slides up and down the anti torsion rope ensuring a perfect sail shape on every point of sail.
