Anti foul

neil.mccrirrick · 19 June 2021, 06:37

My rib is now ona mooring and will be long term. Unfortunately it had to go in before there was opportunity to antifoul

The mooring does dry out onto mud at times on springs so I can get to it and get some growth off it

It will come out for winter

I've never anti fouled before. Rib is capable of over 50 mph I'm assuming I will need to clean and apply a primer and then antifoul. Seems there are lots of different types. Any advice re what to apply and how much will I need?

Hull is 6.9 metres

International have some application guides on their website and the data sheets will often tell you what you need to do in terms of preparation.

Mark the waterline before pulling the boat out to paint it.

Make sure you thoroughly clean and then abraid the hull (below the waterline) before applying the primer. Also allow adequate time between coats. Drying moorings will likely discolour the antifoul and hull gel-coat over time so annual pressure washing/repainting will likely be necessary.

Personally I'd go with copper coat if its staying in for long periods. Strictly speaking to protect from osmosis you should apply an epoxy coating system before the antifoul to fully waterproof the hull (gelcoat is micro porous) . Copperslip is antifoul & epoxy coat in one system it lasts many more years without recoating than standard antifoul & doesnt hamper your speed as much as traditional antifoul Its expensive but no more expensive than an epoxy coat then antifoul job

Thanks chaps I’ll look into cost and how much etc. Based on the link guyc sent I think a litre will be enough

Kind of like to do it once and forget, I guess copper coat is the nearest to that [emoji106]

I have copper coat. It’s a bit ugly to start with and mine has done two seasons in the water and two or three out on trailer and it’s still brownish. What I like about it is it looks and performs as good as the day I put it on, it’s polishable. Mine is abraded to 600 grit all over for speed and I didn’t loose any speed as far as I am aware from copper coat.

Good to hear I’ve only managed to find aquarists marine that sell it and they have no prices so I’ve had to mail them.

If you are aware or anyone else please do share

Thanks

Another vote for coppercoat, my boat’s been in the water for 2 years now and a pressure wash twice a year keeps the hull clean.
The problem is the tubes on a Solent rib, I think they are in the water when the boats moored? Keeping them clean will be painful, I don’t know of an antifoul that works?

neil.mccrirrick · 20 June 2021, 07:51

They are. Right now I'm hanging off the sides or pulling alongside jn a tender to scrub monthly

I have seen tubes antifouled but I dont think I'd use the copper coat for them something like hard racing applied direct to the tubes would be my choice then if you ever want it off it washes off with cellulose thinners fairly easy. It will need topped up now & then but only a small area so hopefully not too much of a pain

Hi Neil,

Bit of feedback on Coppercoat from me here: Linky

It works, needs a mid-season wash and is a real PITA to apply. You get one go at it and it needs to be right.

It's not going to help with the tubes and they will be a problem on the mooring. If you have access then a quick spray with dilute chlorine every few weeks will keep them clear. There is antifoul for tubes but IMO it's almost worthless. I have it applied and the weeds seem to prefer it to the tubes. Luckily, it falls off so fast that isn't an issue....

neil.mccrirrick · 20 June 2021, 10:36

Thanks Willk link sends me back to my post? I've no experience of doing this and most likely it will be end of season so need to clean all the crap off and probably have to do it on the trailer

So as a novice am I better with an ablative hard antifoul?

There is so much product on the market choice is overwhelming. Hempel seem to stand out but the product guyc linke too look going too

Coppercoat needs multiple layers and the mixed batches go off very quickly. The RIB would be better completely raised and indoors. It's not rocket science but IMO requires all ducks firmly lined up and no f@rting around once the job starts.

neil.mccrirrick · 20 June 2021, 12:02

Top write up and feedback. I think it maybe more than I can achieve unless I get it into a shed. Good for thought [emoji106]

Ferryman · 20 June 2021, 15:02

tbh it’s the only reason I’ve changed away from ribs, they’re a pain to keep in the water.

gtflash · 21 June 2021, 21:39

Use non foam rollers too as the epoxy rips the foam out off as it gets sticky.

Ours is on trailer sailor type contract where normally I would call and they lift it in and out etc. To save the number of lifts and make it more convenient for us its parked behind our main boat April to October and gets lifted and scrubbed every 3 weeks, and used a lot in between. It had some residual antifoul on the hull when we got it but the sterndrive is not antifouled. It works for us (so far) with no drop in performance thats noticeable. Regular use and the occasional lift and scrub works.
