F2 EcoHull

Wir hatten uns im Jahr 2025 entschieden, F2 EcoHull anstatt das inzwischen auf dem Bodensee verbotene VC17 zu verwenden. Die Verarbeitung war problemlos möglich. Bei Fragen war der Support von Julia immer schnell und zuverlässig. Wir würden uns jederzeit wieder für das Produkt entscheiden.

We rebuilt our underwater ship in March. Four days in a row, one coat of Hempel Light Primer, the Adhesive Coat on the fifth day and the Top Coat on the sixth day, unfortunately without glitter. After four weeks in the unheated hall, we went into the water on Fehmarn on April 17. Today, after six weeks in the Danish South Seas and only 110 nautical miles, brushed the hull from a dinghy for the first time to remove the considerable growth. It was very easy to remove from where I went. See pictures.

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

We coated our boat with F2 ECO a year ago because we wanted a durable and environmentally friendly anti-fouling solution. We have coated our CopperCoat with F2. The application was simple and easy to do in pairs at 40 feet, because you can also divide the different layers over several days. We are very satisfied with the result, and after one year in the Mediterranean & Atlantic (Canary Islands), we can say that biocides are no longer needed. The fact that you jump into the water from time to time during the season to get your fuselage clean is no different from our previous CopperCoat. But with F2 ECO, you have the big advantage that the growth is not stuck, but can simply be wiped away. So you can't access it with a spatula, but with a soft brush. And that makes cleaning much easier and much faster! In the meantime, we had to get out of the water once to repair the saildrive. On this occasion, we high-pressure cleaned the coating, which was possible without any problems. It still looks like new - even better, because it's now much harder than it was at the beginning. We are very satisfied!

I coated a 5 m long sail4peace dinghy with F2. When I pulled the boat out of Lake Neusiedl after 6 months, I washed off the muddy film with a high-pressure cleaner in 10 minutes. The coating is as good as new! I'm happy with F2! Hello Rudi

Our boat (Jeanneau Prestige 46) is located in the Croatian Adriatic, Dalmatia. In 2023, we had the antifouling rebuilt with International Micron 350. In preparation for F2 antifouling, the old antifouling was sanded to the fuselage and completely removed from shafts, propellers, trim tabs and rudder blades. All parts were then cleaned with the cleaning agent in accordance with the instructions and painted with a roller. The primer was easy to apply, the other two layers had the consistency of honey, which was very laborious. With an area of around 65m², the two of us needed around 12 hours per shift. For the colorless last coat, it was very useful that we had chosen mica interspersion, otherwise it would have been difficult to see where the paint had already been painted. However, when the sun shines on it, the boat looks like a disco ball;) .For people who wear glasses, please note: the splashes from the last layer cannot be removed from the glasses! I still have them on today - 8 months later. When lifted into water, the coating was damaged at the corners by the travel lift straps despite drying for 48 hours, even though we had placed a film between them. This will then have to be revised next spring. After 8 weeks, we were back on the boat, with almost no buildup. Greenish slime at the water pass level was easy to wipe away with a sponge, as were small flat mussels. Driving at higher speeds (30kt) didn't make it go away. A further 12 weeks later, there were significantly more of the small flat mussels, but they could also be wiped away. I used a wooden spatula from the galley, which was the fastest, about 1 hour. There was almost nothing at the keel, it grew more upwards, most of it just below the water pass. It was our last vacation in October, when some mussels had set in again, but it is always only one type. Let's see what the boat looks like next spring. I can already imagine that everything goes well with the high-pressure cleaner. While the adhesion of the old antifouling to the fuselage has been very good so far, the material holds very poorly on the metal parts. However, F2 had already said this before, unfortunately the material for these parts was not ready in time. Here I really hope for the new propeller kit. Finally, I have been very satisfied with the coating so far. By October at the latest, I already had clearly visible growth on my trunk.

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.
