To antifoul - or not?

[frderek]

Hi,

My Westerly Merlin 28 is on the drying-for repairs to the rope-stripper. I have pressure washed her to remove weed and notice some patches where the antifoul has come away completely but most of it seems OK. She was last antifouled last April so is overdue if I am to continue to use antifoul. HOWEVER I plan to have her lifted out (either over winter on in the spring), slurry-blasted to remove all the old antifoul and then treated with coppercoat copper/epoxy. So the question is do I treat her all over now, treat only the bare patches or not bother at all?

tia for your advice,

Derek

a/f now

be sure that copper coat is economical for you.

3 litres of Basic AF is around £40 plus a morning's work to do the lot. Summer is the worst growth period and the bottom will look like my garden by autumn!

Coppercoat is really all or nothing. Of course, you can treat patches - you always have to, to do under the support pads - but the more you can do in a single session of application, the better as that forms a chemical bond between coats.

Yes, I realise that and being a bilge-keeler there won't be any support-pads(?). The question was, do I need to spend money on conventional a/f now, or just let her fur-up a bit before the autumn lift-out? I may compromise and buy a small tin and do the bare patches

prime the bare patches with under water primer

I'd just slap some cheap eroding AF on the bare patches.

Good decision on Coppercoat, BTW.
