Copper Bottom

[TiggerToo]

Does anyone here have a Copper-"bottomed" hull (instead of conventional A/F)?

How do you deal with small "dinks" in the cover that are likely happen thrughout the lifetime of the treatment? Is it possible to patch up with copper-resin - or do you patch with A/F?

The Copper Coat (or whatever the trade name was back then) on Rampage is now nearly 13 years old and has not needed any touchups - which I suspect is commmon for most fin keeled yachts, as you'd have to work quite hard to ding the hull without doing something quite radical to the boat. For a flatter bottomed craft, that might not be the case so I'd have some of the stuff for patching if required when lifting out rather than slapping on conventional antifoul.

About a week after launching with nice new Coppercoat on the keel I sailed over an unseen fishing float made of polystyrene blocks tied together with stainless wire. It left a scrape down to the iron about a foot long, plus extended scrapes rather longer down to the primer.

At the beginning of the next season I ground the damaged area down to bright metal, applying West epoxy (which I already had), then applied a repair kit from the manufacturers. It's a lengthy process but it has been totally successful.

As time goes by, CopperCoat hardens, after a year it is harder than the hull I suspect.

Any idea of the shelf life of this repair kit?

I am in the process of having coppercoat applied. The work has already revealed some badly repaired earlier damage and consequent damp, so has been essential.

I have used Coppercoat resins that were five years old, seemed OK to me. Not sure that's what the makers would say though.

Hi, Coppercoat can be purchased in 1 litre Kit, from the manufacturer. It comes in three parts.

I've had to patch up our trailer-sailer twice. It is available in 1L / 1Kg packs, but even for a patch you need to apply 4 coats, and it is in 3 parts - resin, hardener and copper, so get yourself some scales.

they'd say buy a new one. I'd say make sure it never gets cold, and check the white pot. If it's split like sour milk it's knackered otherwise I'd use it.

You can get 1/2 litre pots.

And galadriel you suspect right.
