The drums of the new Series-S and Serie-E winches are featuring vertical ribs placed in an asymmetric order with uneven distances between the ribs. A line under load will deform over the ribs but when easing off the line over the Seldén drum, all indentations are not simultaneously reaching the next rib. The line will have less tendency to “jump” out but will rather slide out with control. Seldén calls it Asymmetric Rib Technology (ART).
Tacking and gybing made easy
The S-series simplifies the manoeuvre of tacking and makes the handling of a highly loaded sheet safer and quicker. The grip on the winch drum combined with a unique self-tailer enables the trimmer to pull the slack out of the sheet with the line sitting in the self-tailer and with the winch handle in position. A great advantage for the racing sailor who can pre-load the sheet into the self-tailer of the windward winch prior to tacking and then sheet home and set the trim of the jib instantly on the new tack. Simply pull in the slack and turn the handle a turn or two to get full tension. The cruising sailor will appreciate simpler and safer manoeuvres by not having to hand hold a tensioned sheet whilst trying to load it into the self-tailer and searching around for the winch handle.
