Ours was done that way. The surveyor said it was the only way to get an accurate reading with the ultrasound equipment he was using he also put on some gel just like they use on a pregnant womens stomach again to make the device work effectively.

 

 

perhaps there are differfent types of machine but ultrasound needs to be in contact with the bare metal normally and as I say above you should use the ultrasound gel also.

 

Ours was too, he didn't take the whole lot off, just a tiny bit.

We had Wot Ever surveyed a couple of years back for the Insurance company (and my peace of mind) and our surveyor did exactly the same. It was out for blacking however, so didn't matter.

If the hull has ordinary single-pack blacking it's a simple matter to touch up anyway. Watch out with 2-pack though. A boat which was tested a couple of years ago by grinding back the blacking, & the spots were carefully cleaned & repainted with two coats of the same (allegedly surface-tolerant) 2-pack, after taking out of the water this year & washing off, all the surveyors spots were back to bare metal. I'd certainly favour the multiple-echo type of ultrasound tester for boats painted with 2-pack. They don't work through tons of crud, but they will work through a hull coating that's in reasonable condition.
