I'd feel the same way. However, (and you may already be able to tell this) it would give you an idea of the overall shape of the hull. I don't mean condition, but rather if she's gone hogback. Overall, thats a great boat you have. My family had a wooden 40' bay boat when I was a kid, and it had the same style portlights, and was lots of work... but lots of fun as well.
