Is there a gadget which will measure the thickness of painted steel sheet from one side?  I am thinking of buying a steel boat.

Not that I am aware of, but a big F type long reach caliper might be able to reach around a gunnel.

I have a cheap digital one that I use once in a great while, and in fact the last thing I used it for was measuring the thickness of a boat hull.   That one had a small round gunnel and I was able to use the caliper by itself, but if it had a wide gunnel I might use a 123 block or a 246 block to help with the reach.
However, be aware that there may be reasons for the bottom of the hull and the sides of the hull to be different thickness.  For instance a jet built for running a rocky river "might" have a much thicker hull on the bottom.
I don't have a caliper that can reach around and measure the bottom.
Another method, if its a commercially made boat, might be to look up its specs online or call/email the manufacturer and ask them.  A couple years ago I picked up a Tracker to add to my stable of sea horses, and I found its specs saved on iBoats of all places.
