antifoul

[topcat1]

Hi all before i ask ANOTHER question i'd like to say thanks for the advive on gettin my new boat home. I hear so much about different parts of antifouling a boat, while mine is out of the water id like to know how to do it from start to finish and what product to use. My boat is as before a progect 31 and on hard standing. would a steam power washer remove the old antifoul?
cheers topcat1

Where are you going to be boating as different antifouls work better for differing conditions
the steam cleaner will help as will trying to identify what a/foul is on already
Its not a fun job but very satisfy when finished.Start looking for virgin volunteers now

Have you tried asearch on a/foul. as its a common topic?
I think there is a guide on YBW.COM if you are totally in the dark.
Anyway, to get new a/f to adhere, you obviously need a stable surface. Quite what route you go, is up to you. You can get the hull blasted, then, maybe epoxy it, and then whatever a/f you choose. Or you can just scrape off the loose bits, and either 1.put on a primer coat and then a/f 2.chance the old and new a/f will be stable and just a/f over the top. I ve tried most ideas on here about removing a/f except blasting, and I found a large angled decorators scraper (Wickes/BQ etc- 40cm long £7) work very well, though it took maybe 3/4 of a day to do 34ft.
I m not sure steam will remove a/f... havent heard of that idea. Might depend on the type of a/f on the boat. Quite which a/f you then choose to use is about as subjective as which boat wax you like

Hi the boat will be on rivers up and around York. I dont even know if the boat needs antifoul but while its out of the water thought it would be better done. i will only have just over a day to do the job but there are 3 of us doing it so it looks like it will b a matter of steam washing then scraping off loose and painting over with new. Will this bee ok?????

Well, I think you need a dry hull if you expect the a/f to stick. In that case, I d just scrape off the loose stuff and slop some gloop over

Use a pressure washer not steam. Steam may easily damage the hull. Quick rub down with coarse paper, then use a roller for the antifoul. I am assuming she is not new, and will have been previously antifouled. If you keep her in the water, she will definitely need a/f. Do not use hull a/f on the sterngear. This will probably be ok in a river without a/f. While she is out, I would recommend renewing any anodes.

" I d just scrape off the loose stuff and slop some gloop over "

Agree with that.
With the sort of speeds your boat will do,there is no real advantage to striping back A/F to original gelcoat.
you really want start to clean as soon as boat hits the quayside.!!!!!!!!!!!You want the hull still dripping wet,so give a good soak in your case.
With my boat which is similar to yours in age, performance and location,would scrape off barnycules/weed with garden hoes/scrapers then fairly vigorous jet wash to remove any loose poorly attached flakes of old A/F.
Leave to dry off overnight.
Mask everything up.
Start from keel and work your way up.Any A/F left give area along waterline/bootop a 2nd 3rd and 4th coat until tin nearly* empty.
You probably only need an inexpensive hard anti -foul,no need for daft priced stuff with added diamonds :0

*Keep dribble in bottom of tin handy along with a brush.When boat lifted in slings you can bosh the spare paint where support blocks prevented you putting on A/F.

Ps.NOW is the time to check all your seacocks.If at some point you have to show them a bit of violence to get them open/shut,best they fall to bits when you are on dry land

The beers are on you when I come up to Naburn later in the season

I agree with Fred, get it as wet as possible, its so much easier to do while everything is wet.
I got conned into doing this one on my own, out on Friday, back in on Monday, although I aged about 10 years doing it.
As has been said, it's worth changing the adenoids, especially if the salinity is different, ie sea, tidal river, non tidal.

From this....

Anodes

As "Unit18" has said check the anodes you'll need magnesium for york above Naburn Lock

While we are on the subject

Distinctly remember asking for my rope back,the boat needs two bits of rope when moored up apparently.
The Seaweed is yours to keep.

 

[Nauti Fox]

Too late now matey, It's doing a wonderful job holding me trousis up.
Don't worry, when you lift yours out you'll probably find some on one of those rope holders that used to be propellior shaped.
