Perhaps a 4-bar linkage (i.e. Farrier type) anchored to a central “toy chest” might do the trick. It would keep the hulls upright when folding.

The Farrier system would probably end up dumping parts of one or both hulls into the water as it folds -- it's more suited to a trimaran than a boat with two hulls. Plus, I'm not sure about it handling the sailing loads from the mast. And if you want to collapse the boat for a marina slip, there's a lot to be said about not having to apply antifouling paint to the hull sides.
It would be easier to go with either telescoping beams or a scissors-beam like the cat2fold catamaran.
The telescoping beams would be simpler and lighter, and would costs less -- not just because of their simplicity, but also because the scissors beams are patented and would require a $1,200 license.
However, I'd go with the scissors style to make collapsing the boat on the water as easy as possible while singlehanded.
