USA banning copper-based antifouling

Unless they find a suitable alternative, and to date nothing works, smaller leisure vessels will simply migrate to somewhere without the restrictions where copper and its compounds (its not clear on this) are still accepted. Fuel usage and costs will soar.

The leisure marine facilities for 'smaller' vessels will find activity reduces, except those willing to power wash monthly, and the income stream will reduce.

The logic of allowing vessels over a certain size to continue to use copper defeats me.

Possibly, then, reality will sink in. Their smaller government vessels, police, fire search and rescue etc, smaller ferries are going to underline to authorities that until there is an alternative its simply unrealisitic.

Fortunately it will all pan out somewhere else first.
 
On the positive side, it may produce much better equipment to regularly clean recreational craft's bottoms.

As mentioned, commercial shipping is a mystery that can probably be answered as 'big shipping' is to 'big pharma' , the power of lobbying etc. Like tax on aviation fuel worldwide.

Recreational is always going to be an easy target particularly boating rather than agriculture where massive amounts of fertiliser/animal waste finds it's way into the rivers and seas creating many of the current problems. The rub is that most of the plant material grown is to feed animals and not humans.

EU 45 antifouling contains, would you believe, 45% copper oxide, which they claim is the highest available.

Which I discovered a couple of years ago was actually rubbish antifouling on our boat on the River Deben. I've never had so much fouling when laid up in the autumn. I'll never use it again.

Ah. Anyone know off the top of their heads how much copper as a percentage is in (say) Cruiser UNO or Tiger?

I've always thought it was zero? Don't they contain Copper Oxide, as opposed to copper which subsequently oxidises? Coppercoat is copper but that's not a paint.
 
Looking at the (Irish) Biocidal Products Register , most popular brands of antifoul have about 30-40% Di-Copper Oxide as the main active ingredient often with something like Zinc Pyrithione as a further additive. I can't recall how to work out the relative mass of Copper with 30-40% Cu2O, but I'm pretty sure it will be outwith the US limits!
There were a few varieties with 25-30% Cu2O range , and a few with 40-50% Cu2O range, but most are in between these extremes.

1 mole of Cu2-O is 66g, So if you had a 25% Cu2-O paint (which looks to be as low as any might be, and might be useless!) has 21.9g Copper so ~22%.

Just asking as the OP quoted:

"In 2011, Washington became the first state to adopt a no-copper paint rule. And from January 1 2018, no new recreational boat up to 65ft can arrive with copper on its hull and no copper can be sold or applied to a boat after January 1 2020."

Which stated copper rather than copper dioxide.

Would the ban apply to Coppercoat as well? It's not eroding or soluble so isn't a hazard?

Why not? It’s a paint and the law says
‘Beginning January 1, 2020, no antifouling paint containing more than 0.5 percent copper may be applied to a recreational water vessel in this state‘.​

It may be stupid to lump non-eroding paints together with ones that leach into the water, but this law draws no such distinction.

I do notice that none of the three provisions in that law prevents you from antifouling your yacht in a neighbouring state and bringing her back - but that might be a long sail!
 
Pardon if I am stating the obvious but the legislation is the product of the liberal whacko's in Washington State which is distinct and not to be confused with Washington D.C., as such it has no bearing beyond the borders of the State of Washington. The remaining 49 states still recognize common sense....
 
Ummm ... this is what the legislation actually says:

RCW 70.300.020
Antifouling paint containing copper.
(1) Beginning January 1, 2018, no manufacturer, wholesaler, retailer, or distributor may sell or offer for sale in this state any new recreational water vessel manufactured on or after January 1, 2018, with antifouling paint containing copper.
(2) Beginning January 1, 2020, no antifouling paint that is intended for use on a recreational water vessel and that contains more than 0.5 percent copper may be offered for sale in this state.
(3) Beginning January 1, 2020, no antifouling paint containing more than 0.5 percent copper may be applied to a recreational water vessel in this state.

Hmmm.. as other posts have asked, does this mean metallic copper or does it include copper in compounds (e.g. copper oxide)? Rather like the distinction between banning chlorine in your local chippy (good idea, death by poison gas not advised) and/or banning use of common salt (flavouring chips desirable though maybe medically suspect). I wouldn't put metallic sodium in my curry either, though I might add salt...

Serously, I think it's not clear in the extract from the regulation posted above; maybe further bits of the full legislation make it clearer.

[Edit: I now have read the full text of 70:300. Still not any clearer! It might be possible for a lawyer (for the defence of an offending vessel) to point out that copper oxide is not "copper" any more than rust is "iron" or limestone is "calcium"; after which the lawmakers would no doubt amend the regulation to include specific copper compounds to be banned, since that is what I'm pretty sure is their intent. ]

And it's handily out of the way on the wrong side of the continent, up North...

It is far from the best that we have used in the Med. We hauled out in Palma Mallorca, where the local agent persuaded us that this would be the ideal stuff for us, particularly as the price included delivery to the boat. It wasn't a disaster but nothing special.

We were living in The Netherlands when they introduced a similar ban (for mistaken reasons, as it turned out. Mass deaths of fish turned out to be due to industrial discharges, nothing to do with copper at all). Most people we knew just went to Belgium to have conventional antifouling applied there.
 
As Bozlite has pointed out the legislation specifically mentions paint. Coppercoat is part of the gelcoat and no more eroding than the copper containing propeller or through hull fittings, thus coppercoat is ok.

Coppercoat is a paint when applied, a copper loaded epoxy paint, no mere semantics.

Don't get me wrong I think the ruling is a bad one but what are the facts regarding pollution by copper or copper compound anti-foulings?

As I asked before, if coppercoat is non-eroding, why does it need replaced after ten years?

Is there more to the legislation than this? The way I read that there is nothing to stop cruising yachts that have copper based antifouling from visiting their ports so I'm not quite sure what all the fuss is about.

No, that what I made of it, too. I think the newspaper quoted by the OP must have misinterpreted or sensationalised the implications. There certainly don't seem to be implications for visiting boats (nor, indeed, for boats already there - until they want to buy some antifoul).
