it sails the same...
here are a few advantages and disadvantages, depending on your point of view, pocketbook and agility.
with a headstay and a forestay, you need to have a larger sail inventory.
the two different placements of the stays will allow a a dedicated storm sail to be set more effectivly...
the head sails are smaller and easier to handle on a wild deck
good sail storage
and markings, is more necessary with the greater inventory.
more sail plan combinations available
its easier, but still takes longer to set up/take down two sails than it does one...
a cutter rig has more advantage when crossing oceans, than it does as a weekender or coastal crusier.
make sure it is the original factory rigging plan before spending lots of money on it.
My Cal34 also has a forestay and a headstay, such as a cutter would, but the rigging plan is NOT a cutter rig plan.
some boats, such as mine was re-rigged for ocean passages, and so another stay was added to fly a storm sail better, but this does not make it a cutter.
I removed my forestey wire, so I do not have the inner forestay rigged on the boat... just the headstay.
someday when and if I decide to cross an ocean, I will reattach the cable so it could be used if needed, but until then, im going to keep things simple and out of the way, and try not to be a "poser"
