I understand the need for a hinge system, but was wondering if the aft batten could be tuned to give a fair curve rather than the double wish bone hinge set up.. I have a camber inducer on one of my sail board rigs that has essentially the same concept of a controlled entry wing section with a batten that flops from one side to the other, though it relies on leach tension to control things rather than individual strings

> If you use a flexible batten only, it will be too stiff in light airs and too bent in heavy winds - the opposite to the requirement. In addition a flexible batten may bend the wrong way forward of the mast and finish up as an S-shape.
