How many layers of Antifoul Paint?

Not an option in Oz. Environmental requirements will not allow us to wipe down on a beach, in fact we are not allowed to beach at all in NSW. I received a warning from our Water Police 3 months ago. Sad but true. Contradictorily we are allowed to wipe down whilst afloat in the water. So we can do what you are suggesting, but in the water, but it would be difficult to change anodes (though depends on your anode) and props are an issue. Here I cannot leave our props for 3 months once they start fouling.

If I were using an ablative and was going to wipe down, to get off the slime, and using the yacht frequently, so that it would automatically ablate (or if I was a bit more aggressive with my wipe down) I would use 3 very generous coats (as coat thickness is in the eye of the applicator). If I had a little left in my tin I'd apply 4 coats rather than waste it - but I'd preferentially give extra over and above the normal extra to the high wear area, waterline, leading edges and trailing edge of rudder. So rather than 4 coats I'd use it on the high wear area and after that finish off whatever was left.

But I would only do this with an ablative - if you can tell the difference in your yacht's performance with 4 coats rather than 2 I'd be sceptical.

You need to decide how you are going to treat the prop as most treatments will only last 12 months?, so what to do subsequently? Most conventional prop treatments cannot be completed efficiently between tides, not sure about Prop Speed (and Prop Gold). If you took the prop off when you dry out, treat over a couple of days and then re-instal that would work?

Not sure if this helps you very much!
