Hi all
Slipping the boat on Friday to give her a wash and a paint after 17 months afloat since the last time it was done
The last time i did it i only rolled on one full coat and a second around the waterline and leading/trailing edges as she has a lovely smooth bottom with no build up of antifoul unlike my previous Spacesailor that had large patches of build up
The locals down here seem to think that with the cold water temps down here one full coat is enough
Also had a bit of a google and it appears that one of the yards in Hobart agrees as well hobartslipyards.com.au/work-faqs/
Just wondering how many coats others on the forum apply
Regards Don
It depends on how thick you can lay it on (brush or roller) and how much time you have on the slip.
It is all about microns Don. The higher the micron thickness, the better the protection. Consult the back of the tin it comes in or the web site of the paint manufacturer.
I would be happier with two coats than one.
One full coat and double up on the edges and waterline. Good thick roller, one of the cheap ones and toss it after.
we always apply 2 coats here in Brisbane part of the reason is so if you have any misses on the first coat you will pick it up on the second but i have painted several boats that have gone to Hobart and they get at least double the time out of there antifoul down there i think the penguins eat the barnacles
if your racing it really pays to spray the paint as skin friction drops dramatically also the paint works better as you get a smoother and more even application
One coat. Load up the roller and get it on thick and quick. Stir very regularly with a power stirrer. With all the rain this year in Sydney I'm getting 2years

i recon you will know on friday if one coat was enough 
I reckon you are right
I will take a couple of pictures before i attack her with the Gerni
Regards Don
i used to buy 4ltrs cans and struggle for two good coats . gone to the 5ltrs cans and does it better
I think that last time i used about 2 litres on her
Where the boat is moored in the bay we get a lot of fresh water coming down the Huon River and a little bit out of the Kermandie River on the rh side of the photo past the marina so perhaps that helps to limit the stuff growing on the bottom

I use Altex No 5 and under their recommendations its 3 coats if using a roller. On a Top Hat we get 2 coats per tin. Not enough really and only last just over 12 months in the river.
As I was cruising when I last did mine I put 4 coats on [2 tins] and its still good in a very foul area after 18 months.
Reckon I'll get at least another 12 months.
Actually put over 8 coats on the prop and where the pressure waves occur on each blade is the only place its worn off.
I re-did my 35ft S&S this year. I ordered 15l and just rolled it all on. It was 2 full coats and then another around the water line.
Hi all
A bit of a weather window for the next couple of days before it starts to rain so i will slip her tomorrow morning and hopefully put her back in on Friday
Regards Don

8 coats... how long are you on the slip for??
Only on the prop, one at the start and finish of each of the 4 coats on the bottom.
Will be trying hard anti-fouling on the prop next time.
I was on the hard stand for 4 days as that was the cheap bit of the exercise.

mmmmm ok where would this 4day diy slip be located?
2 coats + 1 coat around waterline and leading. + 3 dives and scrubs last me about 5 years. I noticed not much growth in Tassie when I last visited. Fresh water Dead marinas are seem good for just a bit of slime.
Hi all
Slipped her today and all there was was a covering of slime and a few small hard shells that came off with the pressure cleaner
Gave her a wash and a light sand and rolled one coat on after my mate had brushed the edges so essentially she has one full coat and another around the edges using around 4 litres
Here are a couple of before and afters
Regards Don
Being moored near a freshwater source seems to have a very real effect on longevity.
I have a friend who berths his yacht in Akuna Bay in Sydney. The bay is regularly flushed by a freshwater watercourse.
After two years his boat has barely any slime.
I think water movement helps to keep growth and slime down. Out bay has vey little movement and growth is quite bad 1 year is really all you can hope for.
I think movement is a huge key....and a fantastic excuse to take the boat out.
"Sorry , really cant make that commitment on my free time . ...i have to take my boat sailing or the antifoul will be ruined "
