By way of a follow-up on my question, we did try amking our own antifouling this way:
I went to a ship's chandlery and bought a 5 litre drum of the cheapest antifouling pait they had. An argument ensued with the chandler, who knew me and knew our boat. He tried very hard to disuade me as the paint was useless (his words). I wanted it for its sluffing characteristics. That year I mixed 1 pound of copper powder to a litre of paint. The copper powder was obtained on Aazon, but is also readily available on ebay. It is a fine chemical grade powder.
two years later we hauled out boat and there ws a small cluster of mussels on the SSB transducer and surprisingly few barnacles on the prop (unpainted). Otherwise the hull wasperfectly clean.
We gave the hull a quick sand with 80 grit paper, just to add ome structure to the coating and added fresh coating - this time 1/2 pound of copper per litre. After two years in water in Galicia, where there is very heavy fouling, we hauled out in Vigo. No need to powerwash or anything. the hull was spotless. There was heavy fouling on the prop, which we scraped off, but nothing else. we applied a single thin coating iof the same mix as before.
This autumn we hauled out back in Ireland. the manager asked if he should powerwash our hull. I asked "why". He then looked at our hull - nothing.
so yes, unless your boat is made out of aluminium, this is certainly a great solution.
