Is an antifouling on the ship, yacht, boat necessary?

We always recommend the combination of antifouling with our click system. Nevertheless, we have very good references without antifouling, only with our click system, where only the hull is kept free by high-precision clicks. The decisive factor is the Nutrient concentration in water. However, there are also experiences where e.g. with a high algae concentration or a worse quality of the gelcoat, hard lacquer the click tones alone are not enough, just like the antifouling. The combination of antifouling with the click system always works better than each system individually.

Annual antifouling coatings are no longer necessary, the hull glides better through the water thanks to the lower resistance. The biofilm still remains slightly, but without algae or mussel formation. The hull of the yacht, boat or ship is thus protected against algae infestation.

Due to the very low energy consumption of effectively 30 watts, operation with battery-buffered solar collectors is possible. The Solar Charger is responsible for the control.

The Y-Sonic 20 has a preventive and curative effect on boats/vessels with fiberglas GRP, plastic, carbon, steel and aluminium hulls. The Y-Sonic 20 is for yachts, boats and ships over 10m length, up to 20m length.
