Mein Projekt ist eine Dehler Delanta 78 aus 1983. Ich wollte dieses Schiff top herrichten und fand mit f2 eine , meiner Meinung nach , top Lösung für das Unterwasserschiff. Klar war mir auch, dass der Untergrund zum Auftragen dieser neuen Beschichtung top sein muss. Nur dann zeigt sich die ganze Qualität der Beschichtung. Keine Schwachstellen übrig lassen. Ich habe den Gusskiel demontiert und aufarbeiten lassen. Sandstrahlen , verzinken , Epoxy beschichten! Im Trocknungszeitfenster des Epoxy den Adhesivecoat und Topcoat. Das Produkt lies sich super verarbeiten!! Ja, man muss rollen , rollen , rollen bis es gleichmässig auf der Oberfläche aufgetragen ist. Ist ein wenig wie Honig streichen. :-)) Mein Tip!! Ich habe das Produkt bei einer hohen Sommer Themperaturen 34° verarbeiten müssen. Trocknungszeiten verkürzen sich stark. Ich habe das Produkt mit Kühlboxen auf 21° gebracht und bis in die Abendstunden gewartet bis meine Aussenthemperatur auch auf 21° war. Dann verarbeitet und aufgetragen. Alles top!! Meine Wahl den Topcoat mit Sparkel's zu wählen war super, da man so erkennen kann, wo man schon aufgetragen hat. Im Endefekt sieht es auch super aus !! Dann die Trocknungsphase. 8 Wochen frei hängend an den Wanten und Achterpüttings. Diese waren natürlich verstärkt. In der 10 Woche ging es auf den Trailer zurück mit Packpapier auf den Trailerstützen. Die Beschichtung ist entsprechend hart, dass da nichts mehr passiert. Entscheidend ist, das man keine falschen Kompromisse macht bei der Verarbeitung und natürlich bei der Vorbereitung des Untergrundes!!!! Ich gehe auch keine Kompromisse ein bei der Renovierung dieses Bootes. Es ist mein Boot und ich bin damit verwachsen ! :-)) Ins Wasser geht das Schiffchen im Frühjahr 2027. Dann kann ich ja nochmal etwas schreiben. Ich bin bis jetzt von f2 Antifouling überzeugt und bin gespannt wenn das Böötchen im Wasser ist. Die ganze Geschichte des Refit's des Unterwasserschiffs zu beschreiben würde zu lange dauern. Ich habe mich auf jeden Fall nicht von Werften leiten lassen, die sowieso nur genervt von Anfragen, dann doch auf ihre alten Produkte setzen. Um nur keine Fehler zumachen??? Um die Umwelt zu schonen muss man neue Wege gehen!!!
Clean hulls.
Clean oceans.
A biocide-free fouling-release coating that protects your hull for years, not seasons.
Calculate for your boat
protection with proper application & care
biocides, metals and PFAS/PTFE
more speed from the ultra-smooth surface
Once, not every year.
Conventional antifouling keeps your hull clean by releasing toxic biocides into the water. These leach out over time, and the coating usually has to be renewed every year. F2 ECO breaks this cycle: The protection lasts 5+ years with correct application and care.
Inspired by nature.
The secret behind F2 is Zeronic™, a hybrid polymer inspired by nature. It forms an ultra-smooth, water-repellent surface where fouling barely gains a hold and cleans off easily. The effect lasts for years.

Problem

Solution
Independently tested.
Effectiveness
7 months in the North Sea. Fouling kept in check.
In the independent ENDURES test, the panels sat anchored in the North Sea for 7 months. Macrofouling stayed at about 10 percent at most, while the uncoated control panel became almost fully overgrown. Biofilm and soft fouling were easy to remove.
Environment
Independently assessed for harmful substances.
An independent European Registered Toxicologist assessed the full formulation of F2 EcoHull Adhesive Coat and Top Coat: no biocides, no metals, no PFAS, no PBT/vPvB substances. Conclusion: no significant risk to the marine environment.
What boat owners say.
F2 EcoHull
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.
Less effort. Longer peace.
