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!
