Antifouling. Which one is best? We look at 3 including Silicone

Thanks for the video. Very helpful.

Very nice video. Good job comparing anti-foul bottom paint! Thank you! 👍

Great video very informative, who would have thought I would find anti fouling interesting , but I did , sure will help boat owners decide on the best way to go .

Ant an excellent video and very informative. You should be a presenter on the TV! Cid's narration was also excellent. Well done both of you. Kind regards Daryl.

Please bear in mind that copper is a biozid that gets into the sea, stays there and kills microorganisms! Interesting video :-)

Thanks Ant. You are correct on your longevity assumptions on the SilicOne....10 years according to Hempel. Informative vid.

Very informative guys, a lot of people will find this video useful and get something out of it. 👌🏼

Outstanding

Well done guys - very informative! We had our hull scraped back to gelcoat in Tunisia this summer, then had 3 coats of gelshield, a primer then two coats of International Micron Extra (although the crane's filthy strops took a few layers off on relaunch :/ We'll have her lifted again at the end of this year and let you know how it faired. Keep on sharing!

thanks very helpfull

Thanks for this! The anti-fouling that was applied as part of the sale by the previous owner of our boat has been recalled…how that is supposed to work, I don’t know, but when we hauled it out for the winter, just a good hosing off was all it needed, so I’m not complaining one bit…but I’ve bought a second boat now, a little 16.5” trailer sailer, and I’d like to consider antifouling paint for next year. It’s got a little coppercoat left on it, and I’m keen to see how it holds up this year. We will be doing NOTHING like 7 knots, so this answered my question about the silicone based product. Boat speed has a LOT to do with how effective any antifouling product is at keeping the boat clean. My top tip is that if your boat isn’t fast, anchor out or grab a mooring ball on river with a current. It will be a good test of anchoring skills, and you’ll quickly find out if your ground tackle needs updating. 😊❤

Nice video 😊 It really helped me to understand the differences.

Copper Coat seems to be similar to VC-17, which I used on my J-30 sailboat. VC-17 used copper powder mixed into the carrier, and also had teflon in it. VC-17 was as thin as water and dried in less than a minute. It produced an ultra-thin, very smooth and hard bottom.

I have Coppercoat on a 3 year old racing/ cruising Portsmouth UK based yacht and have been bitterly disappointed with performance. I lift it every year, scour, sand, divers down twice a year and still getting weed growth. I had a Bavaria 37 before which required two tins of Blake’s Tiger eroding and a mid-season scrub.

Yes. I’m getting more and more convinced about SilicOne. Ever since Ran Sailing had a discussion about it several years ago. Now I’ve got my boat since three months, so next time it’s ready for a some bottom treatment SilcOne seems to be the choice 👌🏽

Good info here, thanks for making it. Pretty big jump though to assume Silic One will last 10 years. Would be amazing if it did. I use hard/racing antifoal which can be scrubbed as often as needed. Its been over 2 years now since the last haulout and still going ok but the intervals between scrubbing are getting closer. Will be hauling out Nov 2020.

So at the Southampton Boatshow today, I spoke with both a yard who applies Coppercoat and the U.K. supplier. One said abraid with 40 grit until 75% is back to the copper and roller for a racing finish. One said abraid to 180 grit and spray with an increased copper content. The lack of consistent approach could be one of the problems.

Good stuff. Given us a bit to think about when we have Pollyanna lifted shortly.

For myself on Ice Maiden I have a meticulous preparation for anti-fouling. We have just done a complete anti-fouling of Ice Maiden which will last for a minimum of 5 years before we do it all again. First we taken it back to the fiberglass with a bead-blaster. Then we apply 2 coats of etch primer with 24 hours between coats. The hull is then washed down and allowed to dry. We then apply 2 coats of an under-primer, followed by 2 coats of primer. These are sprayed on and allowed to try with a 24 hour dry time between each coat. We then spray on 2 coats of anti-fouling allowing again 24 hours between coats. Finally we roll on 2 coats of Bitumen paint, brushing behind the roller. This is allowed to dry for 48 hours and then we put her in the water. In the 15 years since Ice Maiden was built and launched there has been no growth on the hull with this method.

Sailing Britican tells a different story about Copper coat. . .had it applied twice with copper coat US involved the second time and still they grow barnacles. . . they have lots of videos regarding it from the first time it was applied 'til now
