We run a
genoa on a continuous line
furler and a
jib on a boom wing and wing when running downwind at night so that we don't have to mess with the main. We have run into similar problems when trying to furl the
genoa in winds above 20 knots where we will get uup to 11 wraps on the lower part of the sail before the
head starts to wrap. We find that easing the
halyard just a bit to decrease friction and taking a turn or 2 around the sheet
winch to act as a de-facto line stopper helps a lot. We too usually leave it up with a soft shackle locking the
furler.
It is interesting to note that, before we ordered the genoa, we tested this system with a used sail, using a loop of 10mm
dyneema double braid for the luff
rope that I fixed to the luff of the sail by punching holes in the sail and tying with parachute cord. This apparatus furled the sail much better than the 13mm Gucci anti-torsion line that we are using now on the new genny.
By the way, we shared a marina with a sister ship of yours, "Escape" I believe. What a beautiful
boat and interesting rig!
