Antifouling

Hi all, hope someone can offer some guidance and help.

I am having my new boat lifted out in a few weeks for some repairs to the outdrive and thought I might as well do the antifouling at the same time.

This is the first time I have had to antifoul so am new to all of this, when I started to research which anti foul to use I was overwhelmed with the types of products available.

It has suggested that I use a primer then 2 coats of antifoul?

My question is which product to use?

My boat is based in Brixham, not sure how bad the fouling is down there.

Hope someone can help the newbie.

Andy

Re: Antifouling

JurgenWizard,

You have to be more specific.
Are you antifouling the hull bottom or the sail drive or both.
Do you want one year or will you use multi year.
Is it a sail boat?
Do you want ablative (wears off)

Re: Antifouling

Hi mark,
Boat is a 30ft Motor Cruiser so hull and outdrive need antifouling, would prefer multiyear antifoul to save on lift out cost (and looking like a smurf lol)
Would prefer something that wears away so all of the marine growth dissapears?

Regards

Andy

Re: Antifouling

I just saw a hull painted with Epoxycop, an epoxy ablative, on a boat that had sat at its moorings for a year. There was hardly any growth on the hull which had not been pressure washed yet. Very impressive and it will be my choice the next time I paint.

Re: Antifouling

Andy, the traditional choice of antifoul for stern drives in the UK is Trilux. You can't use some of the stronger yacht ones because the copper content will attack the aluminium drive. Sadly Trilux is only a medium strength - in other words rubbish, that said Brixham is clean water so you might not have the problems of Portsmouth Harbour.

I even complained one year to International Paints, so they sent the rep around to see the problem. He answer was to give me another tin of the stuff for free

In the end I just put a couple of coats of Trilux on it and then used a small stiff nylon brush once a month to keep it clean. Once you get to end of Sept the problem stops anyway.

Oh the stuff in the spray can is even worse btw, so is the blakes equivalent.

Re: Antifouling

JurgenWizard,

Take a look at Pettit Hydrocoat multi year Ablative Antifoul.
Easy to put on. Is not noxious and it's water based, so very easy to thin out with water on a hot painting day.

A lot depends on your Latatude. First check what everyone else in your area is using down at your marina to give you a hint of what is working for them.

And as Pete said use Primacon primer and Trilux on the out drive
Sail Drives and Props

Re: Antifouling

Oh as for the hull, a couple of choices from International or Seajet which we are trying this year for the first time. Has a good right up.

Avoid VC Offshore, it wasn't very effective unless the boat was permanently in use and you can't paint any other antifoul over the top if you want to change. Don't ask how I know but it took 4 days of crawling under a 22 foot rib scraping and cursing to sort it after it all went horribly wrong.

Your choices:

Boatpaint Ltd International VC Offshore

and a review of Seajet:

Leave a one inch gap around the stern drive from the hull antifoul and fill with stern drive antifoul so the copper can't touch the Aluminium.
