I've found this thread quite interesting. My decision to put a furler
on the inner stay was because of the ease of rolling the staysail out. If it's a hank on job that has to be lugged from down below, well most of the time it will probably just stay there. My experience is that I can usually get an extra half a knot
with the staysail set when going upwind (on a similar boat to what I'm building) and that when things get rough the staysail will be the only sail forward of the mast
up until 50, maybe 60 knots. I would hope to not be out in anything stronger and so I am hoping that the storm jib
would never be required. In a real blow, hopefully there would be a bit of warning and I could slip the staysail off the furler
and run the storm jib
up the foil.
Another option could be to partly furl the staysail. This would only be feasable if there was some way to lock the furling
drum so the furling
line was not under load. Has anyone heard of such a system?
