So I'm probably showing my inexperience as a boatie here but if you don't ask you don't find out so here goes.
What happens if you don't Antifoul your hull every year or so but just jump in and scrub/scrape all the muck off every couple of months?
Does the antifoul actually protect the hull in other ways, make it more waterproof etc?
Cheers

the anti is not water proof . you need epoxy coating on the gel coat prior to anti foul paint .

the non anti foul and scrub is a bad idea .

Depending where you are you could be jumping in every few days.
Thats all it takes in warmer waters for the slime to appear , then the growth ,then the barnacles .

Yeah, the warm water is the killer. I'm about 6 months overdue for a recoat but I was thinking how good it was looking before Christmas. Two weeks up on Brisbane Waters in the shallow warm water and I had a good coat of slime and now I can see solid stuff growing.

If you have slime on your hull and you take the boat for a motor around to get it off, whats the most effective, the length
of time motoring or the speed at which you motor ?.

You are not alone.
I was thinking the exact same thing.
Have a nice smooth hull and rub off any growth every 2 months or so. But in saying that, I only have a 26ft boat.

Hi Sam,
I have a bottom clean once a month. At the end of the month I can see, and feel , the thin film of slime.
Motoring does nothing really. Sailing with speeds in the teens doesn't even do anything.it might be good for knocking off ugly bits, but won't do much at all for the film.
Ablative or non ablative doesn't make much difference.
Edit: as noted above, that's in warm water .

Thanks Shaggy....When I had my prop refitted after 3 weeks of being moored in one spot, the diver told me slime was appearing
and to get motoring pronto, which I did. However I have not been in the water to check it out as we have a million man eating
jelly fish floating around the moorings, you know the ones, they're big and heavy and if one gets hold of you you're a skeleton in fifteen minutes. If the water's calm and the sun's in the right place I can see the rudder and any crud that's on it, and to date it looks OK, and of course your water is warmer than ours down here.
