IR view
On a cold morning, with boat worm and cozy inside, you can see the underlaying structure and metal fasteners constituting foundation of the deck. Poor man’s IR view.
When working on deck repair I needed to know where and how the deck panels are connected. IR camera is handy then. Simply warm up the interior, go on deck and start inspecting.
A part of boat’s history could be revealed. Not only how she was built but also traces of previous repairs, plugged & glued repairs or traces of long gone equipment.
Unfortunately, this does not penetrate deep enough to inspect ex keel bolts. Too deep, burried in wood and iron. I’ve tried heating them locally to higher temperatures, in hope that I could then see their thermal image on the outside of hull (with boat on land).
Nope.
But worth trying, anyway.
