the key is the preperation and you wont go wrong, what speeds does your boat do  ? only ask as our painters test different brands , so i can ask whats top dog at the moment |

Can make a massive differenece to the speed and economy, especially if there's a couple of coats. Antifoul has to be applied to a certain thickness, application is therefore usually cracked on & finished a tad textured to say the least. If you can imagine that a perfectly smooth polished hull will have little bite againist the water but a lumpy old antifoul will, reducing speed and economy. Daz, if your boat is in its gelcoat you will want to get a couple of coats of epoxy on her first prior to your choice of antifoul. If your boats already painted (antifoul or another type of paint) but you dont know what coating type it would pay to stabilize whats there with an isolating primer incase your chosen antifoul reacts with whats there. Buy a suiting antifoul, hard one suiting powerboats - Coppercoat is very good, international do a range of copper based coatings for reasonable money. Pick a good day to do it with good weather leading upto it, if you can get it under cover all the better. All the best with her.  |

Hey monkeynuts do you think it makes much difference ? Mine isnt that good, dont keep it in the water .......... just dont fancy getting it all off.... will depend on the power and speeds you need , id think yours will be fine on a trailer long as the is not a thick coat of flacky shite on the bottom the reason i asked is cos some anitfouls at 30 knots just wash off in seconds, and you will be on primer in no time others will be to hard and not wash away at 8 knots and be usless my boat does 20-25 knot and the best iv tested on my boat is AWLGRIP AWLSTAR GOLD LABEL in dark blue or black, it lasted 18 months b4 needing recoat. but it anit cheap at £ 120 ish for 2.5 lt as a test boat i dont mind the price...lol second place for mine is blakes Cruising Performer which needed recoat after 14 months next was international micron extra and needed recoat after 11 months. another resonable one was xm yachting's hard racing but if you left the baot alone for more than a month the weed would not wash off, recoat was 15 months the main idea of antifoul now a days is to erode / self polish and wash off with any bit of weed growth thats starts to build up. another type of antifoul is copper bottom, which has more of a posion attertude towars the weed and lasts for up to 10 years, but its bloody expensive the only other type of antifoul is the bad ass stuff used by the navy and other ships. pure evil is the best why to discribe it. get it on your hands and it burns like hell, get it in ya eye and i dread to think. but getting hold of it is like blood from a stone now a days, we used to use it and it was wicked and would last for 3 years and still be reasonably clean, but i cant get it any more  hope that helps a bit daznewland, il ask the painters soon as thay are back on site (thursday ish) cheers john |

I'd strip off the antifoul & live with the white personally but you could always paint it after with a 2 part epoxy to add some colour but keep good economy. |

well for a boat doing 30knots thay found international VC off shore worked best, but again this must be in the darker colours. black is best by far due to the lack of light refected and will lessen photosinthis (or how every you spell it)/ plant growth found one link to give an idea of prices www.marine-super-store.com/posit/shop/index.php?selectedpartno=INTER+VC+Ohope that helps cheers john |

it will come off bit quicker cos your washing it off bit harder
the test boat is a boston whaler doing about 34 knots and its recoat time was needed @12-13 months and was tested against interspeed which was great till the boat did not get moved for a few weeks, recoat was needed @ 10-11months
i beleave the boat was used 27 times over the year
