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.

I suspect it is not that easy to engineer a FFS for a HP as it needs to be about twice as long and hold a heavier hull. Of course, it can be done, but it would not surprise me it is an order of magnitude more difficult and lose its handiness.
