I actually did install some indicators but they may be to close to the leading edge when I look at the attached photo.

As Matt points out I sort of veered my question as I typed it. What I was remembering the most was my last big air attempts at sailing. I was trying to keep the boat sailing fairly deep and was getting slightly disconcerted (that may be an understatement) by the fill and collapse cycle I got into with its accompanying surges and pitches.
That was when I started the post but it did remind me of the times when I was sailing crewed and wondered about the trim/steer equation. Practice and teamwork would resolve that but I am generally going to be a 1-up sailor.
