I have a Crownline 260EX in Mallorca. It goes into the water around May and out again mid September. The rest of the year it is kept in dry dock. During the season I use around 50 engine hours.
I had a call from the guy who maintains it saying that we have always used HARD antifouling and I should now consider sanding/blasting that off and replacing it with self polishing antifouling. He says that this will cost around 1200 Euros as a one off charge and then the usual antifouling charge each season, but using this self polishing stuff.
Is it something that I must/should do or can I get away without spending the money.
Any advice would be much appreciated.
Thanks

€1200 ? :eek::eek::eek:

Sounds as though he wants you to get it soda-blasted or similar (which can be done for about £3-400 in Blighty - not sure of the cost in Mallorca) before slapping on the new antifoul.

I'd find me another 'guy who maintains it' if I were you. ;)
 
If the price includes lift, store, strip, and re-paint, then it's not that bad. If the hard a/f is not too thick and in good condition, you may be able to cover it with a barrier coat, then paint eroding a/f on top. If you know what hard a/f was used, you need to consult the manufacturer about compatibility with primers and other a/f's.
 
Usually you can apply soft over hard without problems [no need for barrier coat] you should not apply hard over soft.
To be on the safe side Nick H is right, consult the manufacturers, but remember they are there to sell their products.
 
Antifouling advice

Thanks for these responses. Is the general concensus that I would be better of with a self polishing bottom rather than a hard one?????:)

What is your own experience with your current a/f? If it is doing the job, then no need to change. If your hull is encrusted, then you need to try plan B. If it isn't broken, don't fix it!
