I know a professional painter who puts glyphosate in his antifoul ….I don’t think much of the idea , I wouldnt swim in glyphosate or eat fish, scallops etc that have been exposed to it ….actually where are the fish and scallops ? Smack the bugger, that's seriously bad. The glysopahte is really REALLY in water so it'll be fucking far more than anything on the boats arse. We go to great length to keep Glyso away from 1/2 arsed streams in the middle of no where let alone into a place like the Gulf. Holy crap, what is the dude thinking.
I don't know what the nuclear part of the mate anti-foul made it so good but he was admit it was restricted to the vessel and wouldn't cause wider issues. I tend to believe him, he's not a green party voter so he is pro the environment.
Subs have a sort of rubberised coating on the outside, it helps keep them hidden apparently.
Who said you can't use commercial on recreational? Until recently all I've ever used is commercial.

Vivid has failed to impress me. Next time I'm going for the nuclear option. But a mate builds his own anti-foul for his 38ft planing launch and only repaints his bum every 5 or 6 years. The one downside is swimming by the boat for the first year is probably not that wise. Don't know what's in it but I am going to suss. One of the best anti-fouls I ever used was 'borrowed' from the RNZN. Made in Korea based on veggie oil I was told. That worked real well but when the contract came up to get more they went another direction that panned out to be decidedly average, the dumbarses. We should have borrowed a few more tins I know a professional painter who puts glyphosate in his antifoul ….I don’t think much of the idea , I wouldn't swim in glyphosate or eat fish, scallops etc that have been exposed to it ….actually where are the fish and scallops ? That actually sounds a bit lazy to me. If I were going to add an active ingredient, it wouldn't be the most obvious weed killer. I would do some research as to the ingredients that were recently banned, there attributes and properties and go with one of them. Tri-butyl-tin was supposed to be one of the good ones that got banned. Only issue is it bio-accumulates in the environment. It is funny, while I bitch about the AF's not working, it would be difficult for my conscience to add something that I know bio-accumulates to my AF. Not necessarily because of the rules, but due to the impact on the environment.

Has anyone tried these ultrasonic units? I always thought they were snake oil, but I have an issue with Barnacles... volpower.co.nz/sonihull/

Yeah I’ve recently started thinking about adding something ‘edgy’ but effective to the paint before application.
Or what about importing stuff from a less tightly controlled market?

Yeah I’ve recently started thinking about adding something ‘edgy’ but effective to the paint before application. Or what about importing stuff from a less tightly controlled market? Shipping AF gets awfully complicated, as it is classified as hazardous goods or something. So general internet orders would get complicated, You also have to get it through customs. If it is accurately labelled, that is likely to be problematic. Note, this is my understanding, but I have not actually checked. You could always try one tin at a time via Amazon. Small shipments get less scrutiny. Returning cruisers might be able to bring some in? On the 'edgy' angle, I am sure that a suitable compound could be identified that can be purchased legitimately (for other purposes) and added in. It is possibly you could actually make something up with a few ingredients, home bake style. There is a wide range of chemicals available when you go looking. eg Cuprious oxide is a from of oxidised copper. It is what copper coat produces naturally when exposed to salt water. When looking for de-scaling agents, I found almost any kind of acid you may want. It is easy to make various salts out of weak organic acids. Add appropriate metal dust (tin, lead if you are game etc) and you could make an oxide of the metal from a salt made from an acid and some of the elemental metal. Industrial cleaning products, even candle ingredients suppliers (i.e. bulk citric acid, of all things). If sufficient thought and investigation went into it, it would be substantially less harmful than glyphosphate. And probably far more effective. I wouldn't be surprised if the knowledge is already on the internet. Especially the existing AF suppliers, they are likely to have something that may work and isn't too bad for the environment, but can't be bothered with the regulatory approval process. My main issue is barnacles, but as I already have coppercoat, I don't have the motivation to try anything. What would be ideal is something that is toxic but does not leach into the environment (obviously a not ablative AF), and preferably not bio-accumulating, which probably rules out all of the metal based salts and oxides. I think to meet those criteria, you are left with rocking horse shit (something that is very hard to find).

Is your barnacle problem those little things smaller than a pea?
The whole thing is starting to make boat ownership increasingly difficult and expensive in NZ.
Anyone know if this is a trend offshore?

Germans used a rubber coating called "Alberich" it was undetectable to sonar,think it was on discovery or something ,70yrs on rubber still in tack and growth just fell off. Worked as long as they stayed sumerged but on the surface radar would detect them.

Has anyone tried these ultrasonic units? I always thought they were snake oil, but I have an issue with Barnacles... volpower.co.nz/sonihull/They are discussing it over there,snake oil is the common thought,if it works then arent ships using it??

Ships get to use the chemicals that work, and it is area dependent, so ships would need loads of these units. When you say they are discussing it 'over there' do you mean that other place where you aren't allowed to say what you think? It must be an interesting thread, when someone thinks it doesn't work, what do they say? "There is insufficient data to base a procurement decision on, pending further third party verification and trials". Must sound like a group of spin doctors from the Prime Minister's office having a yarn... Fogg, I've just got the regular, common or garden variety barnacles, along with a bit of slime growth. I should clean it off, but haven't gottenaroundtoit just yet. Ben 6 months since we re-launched, so nothing un-surprising. There may be small pea sized ones there, I've kind of made a point of not looking (see no evil, here no evil...)

Has anyone tried these ultrasonic units? I always thought they were snake oil, but I have an issue with Barnacles... volpower.co.nz/sonihull/A mate was working with a local mob who played with units a while back. Mixed results but worked well when things were all in line. From memory, and I'll check, there were ??'s around how many senders/hull units/dodackies I don;t really know the name of per hull i.e. the effective range didn't line up with the manufactures guidelines but water temp had a big input as did the boats speed. Again from memory he reckoned there was good to be had but the technology was still a bit young. I think there was a wee power issue as well i.e. the system sucked a fair bit. I shall squizz him again to get a bit more info and check accuracy.
Ships are quite a different story to recreational due to size, continual use, multi country regulations and all that. They tend to use many square metres of more alloy based than zinc based anodes. Cost and weight I'm told, they do have many many square metres of them. I believe there is ultra sonic options being sussed in commercial and have been form a while. I think recreational is a trickle down from commercial.
My L is now getting barnacles, it never has before. The only 2 changes are - 1 gone to Vivid, which was partially due to that's all I could get during lockdown and 2nd they closed the western gap in Westhaven and that has had quite a impact on the water in the western corners. No vegetation growing there now, only hard shell sea life.

in USA popular "additives" to anti fouling in days gone by included tetrcycline (antibiotics) and cayenne pepper!

What were you using before you went to vivid? and is it still available? And how is the fanny worm going in that western area of Westhaven, if there is no other biological growth?

How the hell did you get 'em' as a moniker when your name is Joe Rogan? He's a ivermectin conspiracy theory fan I believe but then a study out very recently suggests his 'conspiracy theory' may in fact be a tad accurate. We were just talking about how many conspiracy theories there were 6 months ago that are now facts today...but we digress....
That is very interesting fella and no you shouldn't be sharing it nor should I share the results of a trial that I won't be doing on my boat not shortly using the stuff I won't be talking to a man about after lunch
'containing 0.1% (w/v)', anyone know what that means in real measurements?
OK so now a hour or 3 later and it turns out I can't buy ivermectin from the farm shops as it is a drug so you need a Vet. Do we know of any tame or bribable Vets?
I am more than happy to be the guinea pig...or one of my inspecting boats will be
