Coppercoat, Should I remove it?

Hi,

It looks to me like my new purchase might be coppercoated.

I am not intending to keep it on a mooring at all, and will trailer it everywhere.

It looks like the coating has failed in a few small places.

Would anyone recommend renewing it? patching it up? or removing the coating altogether? and if so what to use to get it off?

I know traditional antifoul reduces top speed, but dont think this stuff is supposed to have any effect as AFAIK, any one able to give me any info regarding this?

Personally I think it looks a bit tatty after going blue/green, but can live with it if it does not make any difference to speed/fuel consumption.

Any suggestions/comments would be greatly appreciated.

Gary

Someone on here recently claimed to have GAINED 6kn after having copper coat applied, might be worth re-doing it

I have been following that thread, and it was what promted me to post! I must say 6 knots additional is a huge jump.

Looking at coppercoat website it does show that it goes that horrible blue/green colour after a while, so it might not need re coating. Plus the cost of recoating is gonna be painfull.

Looking for some alternative thoughts, but if none, will probably just touch it up in the areas that need it.

Thanks

Gary

Sandpaper the hull a little bit. If the green stuff goes bronze then it's Coppercoat. I'd leave it on myself; it's a good selling point for the future.

It could be just poxy old antifoul either - the blues can fade out like that. Either way, it's not coming off in this lifetime

If it's coppercoat - I'd give it a quick burnish and touch up.

If it's layers of nasty dead antifoul then it's out with the BA and sander for a day on your back. You're looking at paint or a hard antifoul after that.

To be fair, I think that gain was between removing the old ablative stuff and applying the coppercoat.

I must say it doesn't look like Coppercoat to me (I'm going on what the several Coppercoated yachts here look like when ashore).

Best to burnish a bit of it with wet n dry. If, as GJ0KYZ said, it goes a bronze colour then it's Coppercoat and probably worth leaving. Otherwise, I think it's ordinary antifoul.

I'd try Nitromors (the one for fibreglass) or similar if it is ordinary antifoul first to get at least some off before I resorted to sanding.
