Tim,

With my Scots heritage I can sympathise with the problem of what to do with old tins of AF, its costs so much it cannot be wasted.

We would fully agree with you antifouls (and even, by report, Coppercoat) benefit from a wipe down fairly frequently, the defintion of frequently seems to vary. Leave initial growth and other stuff uses that first layer as the foundations for palaces. This is all very well in warm waters but with advancing years colder waters are much more of a challenge.

Having a, cruising, cat we do find that speed helps with self cleaning, on ablatives, but this is really only effective for the forward half, the aft sections still do not get the water flow and cleaning is still necessary. I do not know whether CC shows this sort of effect. I'd apply it, CC, except for the cost of stripping off the old AF - very expensive here in Oz. The big problems are what to do about props, saildrives and the little section round the saildrive.

The props and sail drive are painted with a special antifoul and in no way any c.c..

We have found that we have very little if any growth on the legs and movement through the water does help to cleanit off.

FWIW, I had an osmosis treatment done, followed by CC.

One year in, not a single barnie and only very light grease like film on the hull.

Put on my dive tank and clean with a sponge.

I read of a procession of FP cats being treated for Osmosis, the most recent was a 2008 or 9 production. I note the '97 Bav being treated. I had thought the reasons for and prevention of osmosis was now commonly known amongst boatbuilders. Have I missed something? Is this still a common problem amongst all boatbuilders?

However if osmosis treatment is done then seems an excellent time to put on 4 coats of Interprotect (or something similar) and Coppercoat.
