Bob,
I'd call moving the beam and centerboards aft 6 inches more than a subtle change.

Bill,
When I saw the change, I thought it had the potential to result in a significant difference. The reality was it did not seem to make a big difference (good or bad) in the conditions we had but it could make the boat easier and more forgiving in big breeze and big waves.
BTW, where the hell were you???? You built that new baby and did not bring her to the big party! George Saunder's boat is beautiful, he is a real craftsman and innovator.
