An honest comparison of F2 ECO with classic antifouling, Coppercoat and other systems.
What does F2 cost for your boat?Why start over every year, when there's another way?
Every season: haul out, sand down, repaint. And every year the same question: what goes onto the hull this time, and how much of it ends up in the water? Most owners take this cycle as a given. A clean hull versus clean water. F2 breaks that compromise: a smooth, biocide-free surface that fouling barely clings to, for years instead of just one season.
Effective by physics, not poison.
Classic antifouling kills off growth with biocides it constantly releases into the water. F2 EcoHull works differently. It forms a smooth, water-repellent surface that algae, mussels and barnacles can barely take hold of. Whatever does settle comes off as you sail, or with light cleaning.
Protection comes from the surface alone, so no biocides reach the water, and the coating does not wear away season after season. That is why it stays effective for years instead of needing to be redone every year. That this effect works in practice was confirmed by the independent institute ENDURES over seven months in the North Sea.

Is F2 ECO right for your boat?
A good fit if
- you do not want yearly sanding and repainting
- you want to switch to a biocide-free alternative
- you think in years, not seasons
Check first if
- your old coating is unclear
- your boat sits unused in the water for long periods
- your area has high fouling pressure
Not the right choice if
- you want to paint over failing antifouling
- you expect a surface that never needs care
- you only want the cheapest seasonal coating
What boat owners say.
We spent the winter in Spain. In Früjar, we decided to use F2Eco. Our underwater was equipped with Coppercoat. aWe had a specialist carry out the work. Because of detailed instructions, he used the primer from International. After consultation with F2Eco specialists, I then had to let the primer ventilate at 20 degrees for 7 days. The two A layers were then applied as instructed. How has F2Eco proven to be so far? Our ship spent the summer in the water in La Rapita. The water is close by and the vegetation has built up well. With my snorkel and then with the freediver, I then cleaned the underwater water with a brush. Amazingly, after cleaning, almost everything was back as promised. What Didn't work: I think F2Eco is a system paint. It is perfectly suited to their primer, binding layer and release layer. As soon as other products are integrated, the system is no longer fully stable and problems can occur. With us: Partial detachment of the binding layer so that only the primer is now present. Although this only affects a few square centimeters, this will result in rework/reconstruction this winter. My name: The system works, but only from one product range

We have had F2Eco as antifouling for over a year now and are very satisfied. The boat is very very fast, especially when first watered and cleaned for the first time after one year. At the same engine speed, we are now well over six knots; with the old antifouling we were around five knots. After a few months, thin-threaded, light green algae growth developed, but this can be easily removed with a sponge, preferably with a steam jet. Overall, the subfloor is very, very smooth, hard and also really good-looking. Let's see what the next few years bring, but everything looks very good.

We applied f2eco last year may 2025 on our 24 mtr motoryacht Yolanda. We spent 3 summer months on the English South Coast upto Plymouth. After that we returned to freshwater in our home province Friesland in the Netherlands. Our typicsl speeds are in the 10 knots range. From November till now boat was onnits berth and not moving.We just drydocked March 2 2026 because of a replacement of propellorshaft besrings. We are very pleased with the f2 eco redults. There was a thin slime layer and some muscles and shells but the were very loosly adhered to the coating and very easy removed with a soft high pressure rinse. The coating looks and feels in pristine conditions. A very few spots need some attention but I suspect preparation onbthose spots was not optimal. All in all very pleased. We will now also apply the propellor protection from f2eco. Ruurd and Yolanda Boomsma Motoryacht Yolanda
Wow! I am super impressed. Compared to the traditional anti-foulings I have used before, this is a real game changer. Firstly, boat speed has increased by approximately 0.75 knots ~15%. I have even managed to win individual ‘round the cans’ sailing races and my division for the season series. In addition, I have won my first handicap offshore race (against much more modern & bigger yachts) and came 3rd in another - not done that before in this boat! Boat speed has remained high through the season; I used a ‘Scrubbis’ sponge to clean the hull whilst in the water. Fuel consumption has also improved but a bit more difficult to quantify as I don’t use much. Secondly, at haul out, whilst there was slime over the hull (as expected), there was no ‘beard’ of weed as in previous years. In addition, any very limited hard grow was super easy to move with my fingers. Whilst on the hull, any hard growth hadn’t adhered to the coating. The shaft and prop were treated with a traditional anti-foul and this had heavy barnacle and weed growth, needing a metal scraper to remove. In the photograph you can see the clear difference between the prop and shaft to the ‘P’ bracket with its F2 Eco coating. The boatyard pressure washed the hull, with the slime and any very limited hard coming off really easily. The hull returned to the before launch condition with the water once more beading off the clean hull! Overall I am very impressed!
I use F2 on our the hull of our rib and what should i say, i love it. After on season as on the firts day.
