They cut out the bolt rope
. It won't fit in the furler's foil.
You can convert a hank-on to a furler sail at the cost of the width of the hank on grommets. It's called a "tape luff" and your local sailmaker
will be happy to take money
for the job. I have several hank-on sails
that were converted from tape luff (racing foil furlers) jibs given to me for free by club racers, and it cost me about $135-$150 per. The idea was that I could use a one-year old racing
sail for four years on my boat until the wear and stretch became an issue even to me, a lowly cruiser. Repeat as necessary and pocket the savings from avoiding a $2,800 new genoa purchase
It's the same logic as buying
a two-year old used car and selling it at four years old. Maximum savings in both directions. I can't see why you can't do the same, excepting that converting from hank-on to furling
requires a bit more sail cutting and reinforcement at head
and tack due to the requirements of the furler.
Good luck with it. If you have a deck-sweeping hank-on, there may be more sail area to sacrifice at the foot as well, as the height of the furler off the deck
dictates where the foot goes. This may reduce sail area enough to make you reconsider the whole thing, which means you may want to learn about downhauls.
