swift1894 Posted November 1, 2019 Report Share Posted November 1, 2019 Is it true that surveyors no longer need to grind off hull coating to get down to bare metal, in order to carry out hull thickness? Link to comment Share on other sites More sharing options...
Sea Dog Posted November 1, 2019 Report Share Posted November 1, 2019 It is if they invest in a meter capable of resolving thickness of the coating. These are available, but not all surveyors have them, hence the practice of removing "tickets" of antifouling/blacking. Link to comment Share on other sites More sharing options...
stegra Posted November 1, 2019 Report Share Posted November 1, 2019 I've never understood why they don't measure the thickness with the coating in place then use a paint thickness gauge and deduct the difference. Am I missing something? Link to comment Share on other sites More sharing options...

Am I missing something? Yep - incentive. Why bother when you can use a relatively cheap meter and scrape some blacking off (or, worse still, 2-pack epoxy)? Personally, I'd look for a surveyor who has bought himself a decent meter so won't need to scrape off any "tickets". Link to comment Share on other sites More sharing options...
