PL had a furling self tacking Jib, when I bought her the jib boom was fixed between the deck and the bottom of the furler but did not work particularly well. I modified it for the following year by shortening the boom and fixing it to the deck around a foot from the front. This worked well and gives a fuller sail when on a reach as the pole effectively shortens. The line to set the jib was led from the. Tack to the end of the boom before going back to the stem and then back to the cockpit this allows the sail to be set, the furling line works as normal once the set line is released. A jib sheet was then fastened to the shroud on the starboard side before passing through a block on the boom and then through another block on the port shroud and back to the cockpit.
Hope this makes sense .
