I was thinking about this last night and I think that the pitch is to great.
If the pitch is trying to push more water than the hull speed, then the extra force that can't move the water would go to moving the aft starboard causing you to go to port.
Just a thought.
If a man must be obsessed by something, I suppose a boat is as good as anything, perhaps better than most. A small sailing craft is not only beautiful, it is seductive and full of strange promise and the hint of trouble.
