It is rather shocking how long it's taking the marine industry to switch away from absolute garbage copper paints to better alternatives, like the mentioned silicon and maybe with a hydrophobic coating over that.
Or Seajet Bioclean Eco, I thought the two looked very similar. Except in price and promised lifespan, which puts Seajet Bicolean Eco ahead of Hempel (if their claimed 3 years can be trusted).
Hi Hugo. Good to see you again, an interesting and useful information video. Thanks to Raymarine for the boat. Your USA videos from Elliot improve the channel. Great video thanks 😊
Nothing new here, while the silicone coatings are seriously easy to clean, if left, like most boats are, the micro and macro fouling will adhere to them and barnacles will eventually eat through the coating. If you are prepared to clean the hull on a regular basis, the silicone coatings are definitely the way to go, but unfortunately the reality is that most boat owners cannot keep up a cleaning program to suit.
I've actually solved the silicone antifouling problem , almost 3 years into r&d and the solution was accompanied by a facepalm after spending so much time in over hundreds of formulations. None of the current silicone antifoulings work, they either keep a very low modulus accompanied by low tensile and shear strength because they can't add enough fumed silica in the silicone polymer hence some sea organisms can penetrate and adhere to it or they make it too hard with little fouling release efficieny, Fuji film had a division close over 10 years ago because they couldn't solve that problem, the akzo nobel companies took massive funding from the EU because of their connections and went around that problem without every solving it, neither international, jotun, or hempel has a real replacement for antifouling, their tensile strength is 0.5-1.0 MPa which is soft and brittle like gelatin, don't get me started on propspeed these guys are scam artists.
That’s why we are also monitoring a static board with the same products and will report back every six months or so. No great difference between boat and board at the moment.
looking at the strips in between where there was no anti fouling. these areas are extremely inconsistent. There are some with very little growth and then there is one with extreme growth. you would expect that they should all be the same. That makes this whole test questionable for me.
@@sailingsolstice the strips in between the biocide products didnt grow anything because of that exactly , the biocide ... the strips between the silicone products have growth because theres no biocide present
A boat "constantly on the move" is not necessarily a representative test boat. If growth happens while in berth, and the polishing under way... I live very far from my boat, and while i use it maybe 1/3 of the year - year round - it's berthed up to a month at a time. No amount of 6 knot sailing polishes those carbunkles.
Bottom paints are bad for the ecosystem. I guess the newer ones are less effective because nowadays they are more regulated and cant contain too much poison.
Too many variables to actually judge, boat static versus well used, open sea, harbour or estuary use as well as mooring in fast or slow moving water... etc etc...

This was really informative and different, thank you. Maybe one time we can get one comparing products designed solely for salt water.
Good comprehensive comparisons.
Looks like the silicone products are the clear winners. Thanks.

What a brilliant video, I'm glad you went to all this effort, very interesting 👍❤️👍
Hempel silic one it is.

But what must be done If you Like To Change To a normal AF after using silic?
Would have helped if you got the order correct when going through with the cloth.

Glad you found it useful and planning a few more Elliott videos from the Palm Beach show next week

Fantastic, thank you very much! Helped me a lot!
I would like to see a hydrophobic coating used and see how it compares.
What was such an interesting test, very illuminating 👍
looks like he got some of them mixed up at the end i though he said tigercoat was one of the black strips at the start?
Looks like Hempel Silic Ome is the clear winner!
All very good if your boat is regularly on the move, but most boats sit still for most of their time. A test for the static boat, perhaps?

I agree and I can't explain the difference between the non-coated areas so I'm a bit confused.

Results are below, including the static panel that they told us about in the video. 👍
Lekker man lekker 🇿🇦
So how is the rest of the boat totally clean?? Looks like the original boat antifoul paint is the best! What was that?😅
I was wondering the same thing LOL.
Yup, I guess they pressure washed it
This isn’t in the US is it? We don’t have these brands
My guess is the UK
so which one would you recommend?
Full results are here: www.mby.com/gear/antifouling-test-2022-results-119924
The only paint to get the full 5/5 rating from us was Hempel Silic-One
Seems
silicon one is the best
Different Sea’s different rules
Great information thank you, I've been looking into hull maxx, has anyone had any experience with this product, it has a 10 year guarantee

Bottom paints in Canada are garbage, only last 2yrs max. Old paints used to last 4 or 5yrs.

Vinyl wrap is better than any paint.
Under the water line?
@@HarryShagnasty-sc9zd Of course, better than painting every year or two.
Utter nonsense
