Anti-foul - How?

Hi all experts who keep their craft on wet moorings biggrin.gif

 

I may have a chance of a wet mooring for my Warrior but will need to do the dreaded antifoul treatment.

 

How high does the line have to be?

Do you have to add any other lines?

 

Not having done this before any help would be appreciated.

Next time your boat is in the water with what will be her normal "resting" load.

Take a quick picture from each side (boats are rarely completely level). Or leave in for two or three days to get the makings of a scum line.

 

Antifoul an inch above the photographed waterline.

 

Don't antifoul too high as it looks naff. Some people like to rise up at the flare of the bow. This is personal choice and serves no purpose apart from looks, but again, don't go too high.

 

1) Mask carefully where the antifoul line will be. Make sure you don't leave bubbles in the tape.

2) Using a fairly fine grade sand paper, lightly rub over the whole hull, etching it. This creates a key for the primer to stick too. Avoid using the likes of "Self Etching" primer. Some people use it so that they don't have to etch their boats with sand paper, but I am yet to find one that works well.

3) Prime using a roller and brush in awkward places (radiator roller).

4) Allow to go off and then touch up as necessary.

5) Apply two coats of your chosen antifoul and touch up as necessary.

6) Remove masking tape ASAP after finishing as it stickls like b@ggery if you leave it on.

 

Keep a little acetone near by for splashes and misshaps.

Use top brand paints like International as the cheaper ones aren't as good.

Don't buy bargain bucket paint from a boot sale etc as antifoul has a short shelf life and this cheap stuff has probably been hanging around for a year or two.

White paint will go a dirty pink colour on contact with water.

Blue and green will both fade slightly.

 

Good luck

Coddy,

All good remarks by Tom, which i agree with. Would add that most antifouls these days are "self-abrading" which means they wear down over a season. No problem for slow displacement craft, but the faster you go, the more abrasion you can expect.

 

Would suggest looking at the harder types of antifoul specifically for faster boats, and reading the accompanying leaflets carefully.

As Mike says most A/F's are self abraiding and on slower vessels they are brilliant, a pressure wash at the end of the season and your ready to go next year. The high speed power boats tend to use the hard A/F in several coats as the chemicals are in the paint and they leach out over the course of a season. However here's the rub (pun intended biggrin.gif ), at the end of the season it's just paint, most of the poisons having gone, and it will need rubbing down to reduce the thickness before you can stick some more on for next year. This is one of the most 5hitty jobs on a boat! sad.gif

Also .......... Moorings? Will you also need a dinghy? If so where will you keep it and launch it? Boats get vandalised on moorings also broken into and stuff nicked. You can't leave anything valuable aboard therefore EVERYTHING has to be lugged to the boat and back again every trip.

 

Having had and used moorings, finger berths, and trailering IMHO trailering is best unless one is filthy rich and can afford a marina berth and pay the yard to do your maintainance. If you are tempted Cobbs, this year, is

Hi Dave,

I'd echo Mike on this one. You really sure you want to moor it? You've got everything to fit, remove and clean down, all eating into your fishing time. You've lost the ability to (easily) visit other ports, your boat and OB will get a lot more hammer from the environment and the fuel will be a pain in the butt. Sharing a small dinghy with ten gallons plus of fuel is no joke. Then there's the worry every time the wind gets up from the wrong direction, the panic about whether the bilge pump will flatten the battery, the inevitable visit from the light-fingered brigade......

 

Makes a little hassle on the slip feel more like a picnic in the park.

going to argue the other way.............but only for alongside berths not swinging!

 

have kept all mine that way; 17 dory, 21 cuddy and now Phaeton.

 

Never left anything of value on board at all - but geting things on and off is nothing compared to trailering!

 

Still had trailer capability and used to go off to Loch Lomond (pike) Brittany (rocks) Plymouth (pollack), Spain (hot) and Poole (sunburn - so Jo made us move the boat there permanently) .............

 

On the one hand it's always been the largest annual cost of owning / running the boat - on the other it has enabled me to use it with the family (or fishing) when I want to.

 

Swinging mooring has the capability of being the worst of both worlds though.

 

Before anyone say's it - yes 200 a month is a lot of money; but some people pay 35 a month to Sky just to be able to watch some football sad.gif

Hi all

 

Thanks for the advice, the problem is I am trying to reduce my outgoings if possible, as I currently have to store the boat away from home so I have to remove everything in any case.

 

I have not committed to anything yet and I am still in two minds about it. unsure.gif

 

For me the advantage would be to "pop out" whenever I wanted without the hassle of launching but then not being able to flush the engine would be another issue! dry.gif

 

The thought of a secure, if there is such a thing, pontoon berth is great but the cost is an issue.

 

Thanks again for your thoughts and how to antifoul.

just to add another spanner in the works

 

Have you onsidered Dry Stacking the boat?

 

I am not sure of costs but it can be done at a few places locally, and as you are paying storage it may be an option.

 

The boat is not in the water so avoids the corrosion and anti fouling problems

 

Staff launch and retrieve the boat at a booked time and while not in use its stored

 

some insurance companies reduce premiums for it apparently.

 

 

I obviousl Antifoul my boat and houndreds of others at work so if you want advice or a chat on what we use pop around.

Dave...I'm on a dry berth at Mitchells (Turks Lane)....it is a bit tidal, though with 65cm of draught I've only had one problem (when I/we missed the channel !).

 

So far so good I must say, and as has been said the obvious advantage is the boat doesn't grow a beard nor does electrolysis have much time to have a go at it.

 

Might not be the answer if you're looking to reduce your outgoings though as this arrangement too is about 2.5k per year (for a 21ft boat) and I couldn't find anything much cheaper when i was looking about.

 

Not sure if I'm supposed to paste a link to them on here, so pm me if you're interested in their contact details.
