My XYacht X372 sport sailboat was faired a few months ago with your Parafouling product. It had been coated in July 2022 with an erodible matrix.
After sanding my hull, my boat looks very rock n' roll with its hull washed jeans,; it is very new, but not necessarily meeting the aesthetic criteria of the traditional navy. (I'm a little old!!!)
To remedy this I bought a pot of antifouling matrix hard navy blue to make a plain band of 30 cm under the waterline, now when I heel over, we do not see the "not finished side" that gives the washed jean effect.
Your recommendations on the quantity 750 ml for my boat fairing are correct. the dimensions are 10m5 at flotation, on 3.5 of master baud and a bulbous keel which is 2m deep. I have 30ml left.
the sprayer in one hand, the cloth in the other, apply Parafouling to the hull took less than 2 hours for one man, including scaffolding movements (which in my opinion counts for half the time) and drying included. And having to do only one layer is great, it limits the costs of dry dock at the site (one day).
I also varnished the Maxprop shaft and propeller (I took care to move the propeller blade gears during drying.
the rest of Parafouling was sprayed on the bow and my hull, facilitating sliding at the heeling angle.
After putting Roscana 2 back in the water, there is a clear difference between before and after:
• When there are crosswinds, for 12 knots of wind I improved by 2 knots: From 6 I go to 8.
• When downwind I gain 1.7 knots
• and it is especially in light winds with wind accelerations that I noticed a clear difference; Roscana 2 is much more alive.
I talked a lot to my pontoon comrades about Parafouling,; most of them showed keen interest.
Depending on their needs, the convincing arguments are:
• Ease of application - only one coat
• Drying time
• Lasts for approximately 2 years (not to be done every year)
• Ecological
• Cost price (especially if Parafouling lasts 2 or 3 years)
o Equivalent price (or even cheaper) than the 2 layers of conventional antifouling
o Lower site costs: Less time at the site, two layers of conventional antifouling require at least one night at the site
o Cost of ownership: A single dry dock lasts for 2 years
Complément d'avis Mai 2023
« Quelques semaines après avoir caréné avec le parafouling, j'ai eu la désagréable surprise de constater que des éléments de couleur venaient se coller sur l'étrave, le safran et la ligne de flottaison. Mes amis navigateurs se sont un peu moqués de moi et de Parafouling dont je leur avais vanté les qualités. J'ai pu tester la facilité de nettoyage simplement en allant naviguer par 20 knts de vent, le bord de portant à 9-10 knts a nettoyé toute la carène.
Facile avec Parafouling, même pas besoin de coup d'éponge. Promesse tenue. Les copains ont trouvé ça chouette.
A bientôt,
