Coppercoat has worked for me in UK waters, the Med and Caribbean. It lends itself to warm waters, certainly for liveaboards, because what little marine growth it does allow is easily scrubbed off by snorkelling. As others have said it is not a barrier coat (but then nor does it leach to any significant degree, which I think is why the US Coastguard, amongst others, has endorsed it). As to its general effectiveness, I’d put it about level with a good conventional antifoul applied annually. Anyone expecting a quantum improvement is in for a disappointment. But, of course, its longevity is the main attraction. The chemistry of Coppercoat can take a little while to get going, however, which is why Ewan and his gang recommend a light surface scrub after new applications in areas of high fouling. I’d suggest this is particularly necessary if the boat isn’t likely to do much moving in the first few months after application. For a boat that isn’t routinely hauled out annually, particularly one someone has gone to the trouble of stripping and barrier-coating, I’d say Coppercoat is a no-brainer. Not least, I’ve met at least half a dozen owners who have gone to that trouble and not Coppercoated. Their view now is “If only…”
