Thanks, all. The admiral definitely agrees that I have an active imagination, which is a good thing many times! And that's probably the case here. We only brought the anchor on board last Sunday and sailed so configured once. Not a large sample. Some one had mentioned the possibility of increased hobby horsing, so I was looking for it. Based on all of what you good folks have had to say, it seems extremely doubtful.
But to answer the various questions:
Tankage is as built. I replaced the two head doors with curtains, removing a bit of centrally located weight, and added two batteries aft (one on each side, but otherwise haven't done much to change weight distribution. She does have a sprit on which the anchor rests on its roller. I will probably move the ununsed CQR off the bow to a more centrally located locker. And I vow to move the beer aft more earnestly next time out!
And I'll focus on more tangible issues.
