Dave:
That article appears in the July? Aug issue 2010.

"IE what is the arm why is it a problem in reverse but not forward? "

Good question. I'll take a stab at answering it. I think the key is that the center of pressure on the hull moves. When in reverse the hull C of P moves well aft. In forward it moves well foward. This would be consistent with any foil and the keel foil shape is backwards in reverse, i.e. sharp leading edge, making it move even more aft. I think that's it.
