Hello all,
any experience or recommendations for antifoul brands to be applied to 30' fibreglass planing hull with twin outboards? What kind of life do people get from their antifoul? As a diver I can scrub down pretty easily if required between antifouls if that helps extend the life.

cheers, Mike

Is this a first application or covering up old antifoul?

What type , style ( ablating) antifould had been used before.

Lasting of antifould depends greatly on how often boat is sed. More regular with a ablating AF and as it is freshening itself all teh time it will leave boat cleaner all teh time .

Big cost differences in chaning over on some brands of AF and if it is a new coat avoid antifoul altogether and get a seapen, boatlift etc etc and it will repay you many times over on fuel consumption , maintainance and evertual resale of the boat



Some old tricks we use . Epoxy undercoat in same colour as boat hull. Use a red colour for first coat and then 2 coats or whatever of the next colour. That way you can see when you are down to the lower coat of antifoul or the base epoxy. Tripple coats on waterline and high wear areas such as keelline and planing surface. We have tried different antifould at waterline and on planing surfaces with some good results but also some disasters. Same in regard to application be it sprayong or rollering.

We wipe our boats and on occasions use sponges, scourers and even wet and dry on hard antifould and ablative ones to get a fresh paint with some algeaside in it.

Your whole antifoul depends on it's application. Some brands require strict drying times and so on and if being applied by a boatyard they simply couldn't give a toss as they know they have you by the nuts in 12 months time.

Some antifould will cope with high UV and


Some universities in your local area may have done testing of antifouls in your loal waters. Their effectiveness is greatly affected by water flow,temperature salinity, boat use and so on.

I won't even go into the issues / corrosion if you motors don't lift permanently out of the water and need antifouling
