The fairing, step by step

The fairing is a very important step in the maintenance of a boat. It’s not necessarily technical but it requires time and rigor. We reveal our instructions so that you don’t make a fuss of the whole process. First, let’s answer a few questions that come up often.




The fairing, why?

The fairing consists of cleaning the hull and passing the antifouling. Plus, we take the time to change the anodes and to check what is happening on the submerged part. As we often say, “prevention is better than cure”. Checking that everything is working properly before the season can avoid most unpleasant surprises.
The fairing is therefore the basis of good maintenance.

When to do it?

It’s advisable to do it before the summer season or before you think of coming to enjoy your pearl. In any case, it’s better to anticipate. Indeed, it is necessary to foresee the availability of the crane, the setting on cradle, the professional … and all that start to be complicated when everyone goes at the same time : in spring!

How often?

You have hardly sailed this year, your boat has remained at the quay … you conclude that it is not necessary to refit. Wrong! The more the boat sails, the less the hull gets dirty. Indeed, the navigation limits the installation of shells and algae.
It’s therefore preferable to refit your boat every year. Like the overhaul of the engines, taking care of the hull is an integral part of good maintenance.

Which product to choose for antifouling?

Very soon, we will tell you more about the product for antifouling. There is a wide range on the market and before deciding there are several points to take into account: the hull material, the speed of the boat, its use, the type of navigation …

The anodes are not damaged, should I change them?

Before answering this question, let us remember that the function of the anodes is to attract corrosion first in order to prevent it from settling on important parts. Hence their name “sacrificial anodes”. Thus, if they do not show any wear, it is because there is a problem: another part acts as an anode such as the shaft, the propeller, the base … Besides, otherwise, that is to say, if the anodes wear out quickly, it is equally worrying. In this case, it is often a leak of electricity, on board or in the vicinity. So yes, you should change the anodes every time you do the fairing.

The fairing, instructions for use

To guarantee a perfect fairing, three stages are fundamental: cleaning, antifouling and finishing. Obviously, your boat needs to be settled in an area equipped to collect wastewater. Wild fairing is prohibited.


Cleaning the hull

Fairing a boat is a bit like painting at home, nothing beats a good cleaning. And it’s the longest part! For this, we use a high pressure cleaner, a squeegee for well encrusted shells and fine sandpaper with water for limestone. For the propeller and propeller shaft, even if these parts are not protected by antifouling, they must be cleaned by scraping and sanding.
We finish this first step by delimiting the areas not to paint: the waterline, the sounder probe, the anodes …

The antifouling

Before painting, make sure the hull is completely dry. Drying time is a very important aspect. Do not hesitate to let a day pass. Then, with a roller or a brush, it is advisable to apply two coats. Also, apply a good dose of product to the waterline. Very exposed to light, it is one of the areas that get the most dirty.
Once the antifouling has passed, the adhesives must be removed very quickly. Otherwise, you may also remove paint. In addition, the adhesives do not support the sun … and for good drying, nothing like a few rays!


If cleaning is the longest step, finishes make the difference. When the boat is put back in the water, it’s time to scrape and pass the antifouling on the areas hidden by the skates. Also, take the opportunity to put the anodes. Finally, check that the boat is not taking water;)


Besides this few steps and these tips, there are many other things to take into account. For this reason, we advise you to call a professional.
