OK. I re-read my post and I don't know how I expected anybody to understand what I meant. It is a bit trippy, and I did not explain it well.

As 'they' say, a picture is worth a thousand words - only I haven't got a picture.

So, for sh-its and g-ggles. Imagine (inhale now), that the transom of your boat was completely see-through glass ( go with it ), and you could see where the stringers attach to this 'glass transom'. At the point where the stringers attach to the hull and the glass transom draw a dot with an imaginary grease pencil on the imaginary glass transom. Now, go to the other side of the boat and do the same thing, draw a dot where the stringer meets the transom and the hull. Still with me? Now, draw a horizontal line across and connect these (2) dots. Good so far ? 'Eeere.

Now, that line drawn - go to the very middle of it. Draw a dot. From this dot, measure straight down to the keel of the boat. That vertical line is the measurement I need.

And, I need: From inside the boat, I need the exact dead center of the stringers.

Believe it or not, but these measurements will allow me to pre-set bunk heights, and keel roller heights for my trailer. My boat is still in the water ( water temp in NY is 52 degress ) and getting ready for the big pull.

Lastly, " How high is up, and if so, why not ?"
