I think you are making a mistake and here is why. You want your boat to balance with just about any sail combination you have up. I can balance my
cutter with
mainsail, staysail, mainsail-jib, reefed main-staysail, reefed main, stormsail, etc. Your pilothouse will already cause your center of effort to be aft. If you put your
sails back there, everytime a gust of
wind picks up you will
head toward the wind.
Last week just outside of Anacortes, I was on a broad reach on a narrow sea between two cliffs. The wind changed suddenly, and with increased force. If I would have had your rig, I would have gone straight into the cliffs, were no amount of fiberglass would have saved me. Since it was 43 degrees outside, the
water was in the 40s, and there was no other boats in sight- well you get the picture. Because the center of effort was close to the center of resistance which was close to the mast, I was able to depower quickly by pivoting my main around my mast, and rolling my
jib (with the sailsail up ) balanced the rig. What could have been a disaster was quickly handled, even though I was soloing.
With too large jibs you could balance the rig I suppose, but I would hate to try and manage your rig with shifting winds or on
mainsail alone.
Lets just say, for arguments sake, that you were out there in 20
knot winds and one jib up for balanced sailing. The wind starts gusting to 30 and 35 knots (common around the Salish Sea) How are you going to depower quickly until you can retrim to the new conditions? Let the sail flap? Bring the jib in? Reducing a jib that size takes a little time, even if you are roller-furling. Now what if the wind changes directions and gusts? The large jib balloons and the many hundreds of pounds of pressure on your winches prevents you from doing anything but letting it out. If soloing this is often at great risk to your hands and self. And you have a flapping runaway jib with no way to get under control except to reverse course and roll in.
Two last points:
A partially furled jib is not an effective airfoil unless it has been cut that way with some reinforcement in the middle of the sail (read $$$).
A flapping jib wears out very quickly.
Just
food for though my friend.
