there are a couple of options for this... the cheapest and quickest is the stanchion mounted bulls-eye fairleads, and they work well.
on a longer boat, or if you want to spend more money, you can buy stanchion mounted blocks to run the furling line thru...
the bulls-eye leads are low friction and are the most common solution and it is what is installed on our boat....
you may or may not have deck mounted bulls-eye leads now, but if you dont, thats good... you dont want them if you have stanchions, as the line still lays on the deck and gets extremely dirty from any fallout that collects.
the line mounted a couple inches higher on the stanchions where the line can remain suspended, it stays much cleaner than one laying on the deck.
dont get the leads mounted too high on the stanchions as it could cause flexing, but 2-4 inches above the deck would be about right...
