I only picked her up last December so don’t know the history of the Coppercoat unfortunately & the survey didn’t mention it either after they did a test scrape. Mind you they also missed the faulty furler and standing rigigng that also needed replacing – much to my wallets/SWMBO annoyance!
The yard have come back with this…. ‘The coppercoat is not active, was covered with antifoul without primer underneath.
Best way forward is to remove existing antifoul, apply Primacon underwater primar, apply new International Micron antifoul’
