I think last years best answer to this question was that with sailing boats it best to antifoul the prop,, and with motor boats best to polish them.
Ive always antifouled mine (except one year in Chi when i polished it and it became horribly fouled) and I use 3 coats of hard a/f.
I dried out "Fairweather" a week or so back to replace a seacock and the prop was pretty clean and the a/f was just wearing thro, This was after 120hrs on the engine for this season.
I was interested to see the post about copper plating trhe prop as I posted a question about this at the end of last year.. which got a mixed bag of replies .. But I still think this would be the best way to go (with brass/bronze prop).
Does anyone know where its possible to get this done in the south?
Last year my prop was anti fouled and it never got that bad. This year it's not anti fouled and is awful - boat moored in Chi Hbr both years.
However, to be fair, I didn't get the prop as polished as I would have liked as got bored of wet and drying it for hours on end...so I'm not really doing a fair comparison of an anti-fouled vs a highly polished prop.

Don't know what the problem is.
For as many years as I have sailed and wherever that was I have antifouled Prop/Shaft/Drive with Prop-O-Drive.
It has worked on inland waters as well as East Coast and lately also on Dutch coastal waters and Ijsselmeer.
I know it's not that cheap, but it is easily applied and it works!
