Selden Adjustable Tack Swivel for GX25 furlers enables the sailor to easily trim the luff of the gennaker. The AdjustableTack 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.
