painted steel thickness

There are. How much do you want to spend?

It's been decades, but I remember we had some sort of I think it was ultrasonic gizmo, with a sensor head at one end you placed on the part, and it measured the thickness.

Peter,

If you're still in Trowbridge or nearby many of the local boatyards should have an ultrasonic thickness tester as IIRC it's a requirement the hull is checked every few years to make sure the hull thickness is maintained.

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

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.

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

Thanks

David,

Yes I am still in Trowbridge, unfortunately the boats I want to look at aren't. :)

Having now looked at some, they all seem to have single digital outputs, which is disappointing - a simple graphical display of reflections vs time would be much more useful.
