ScottiE 174 Posted July 15, 2015 Share Posted July 15, 2015 I think the key is that going forward you need to stay on top of your boat - regular slime control so they don't foul. Regular haul outs etc. you need to also think very carefully about what sort of anti foul you want to put on your boat. All anti fouls are bad - clearly by definition - so if you think that you're going to just scrub off by diving once a month or so - you need to think about whether you go for an epoxy copper coat type product or a biocide, or some other new fangled sh*t!

harrytom 640 Posted July 15, 2015 Share Posted July 15, 2015 maybe the manufacturers need to produce paint that actually works not just claim it works,what one uses in a marina(stagnant water) does not necessarily work in a river. Previous yacht had coppercoat,mud/slime on hull then barnacles get hold and so it goes on.only advantage if you have a fast boat it comes off or scrubs easily. Quote Link to post Share on other sites
Steve Pope 243 Posted July 15, 2015 Share Posted July 15, 2015 The prospect of a manufacturer making an antifoul that really works is not going to happen. 1st reason is that as soon as he sorts out a formula it is off to the environment "experts" for evaluation re toxicity. The 2nd is that a long lasting eficient antifoul is going to affect his proffit margin. 3rd is one that works on wood / GRP doesn't necessarily work on Alluminium / steel etc. All testing for toxicity is done in Marinas where the toxicity levels must be the highest because of the number of boats shedding their protection. Cruisers who actually cruise don't leave a toxic footprint as they are regularly moving. Quote Link to post Share on other sites
