Yes, I do keep coming back to the dynarig. It is appealing. I am, however, concered about how it will behave if caught aback. I hope to build a small one for my test proa this summer (if I ever get the rudders and crossbeams built).
I have thought that if the dynarig battens where flat horizontal plates, wide enough to go around the mast, then a slot could be cut in them allowing the whole sail to cant away from the wind, putting the center of pressure aft of the mast. It would seem that would make the sail auto feathering.
All the arguments about weight aloft, mast stiffness and weight and complexity still argue against the dynarig, though, so I am firmly in the undecided camp.

This balanced rig is designed to work with the wind from either side of the sail as for the Easyrig. The Maltese Falcon appears to get much of its benefit from being single sided - that is the wind only works on one side of the sail. This allows the sail to be asymmetric with permanently curved spars.
I do like the thought of an asymmetric sail on an asymmetric hull (a proa).> except that it is a main/headsail combination rather than a single Œsquare¹
