The keelcrab drone is capable of cleaning up to the 95/97% of the surface area of a displacement hull of a sailboat in the 10/24 meter range and 85/87% of a planing or semi-planing hull of a motorboat in the 10/ 24 meter range.

Even with the stainless inset brush, the keelcrab drone is unable to remove barnacles or dog teeth or fouling that can be classified as aggressive or highly entrenched. First, the reasons why these pluricellulars proliferate on the hull of your boat are basically to be attributed to a mixture of factors such as the particularity of the water in your catchment area (mix of fresh and salt water or the presence in the immediate vicinity of fish farms) an incorrect technical choice of antifouling chemical protective of your hull (or worse, a poorly executed job) or finally the total absence of the chemical protective product (due either to natural consumption or to previous application of anti foul

Our brushes are designed to remove principles ofcoral, vegetation and algae without removing the underlying antifouling, which in numerous tests in a simulated environment finds no micrometric change before or after several passes of the drone. Regular cleaning aimed at bringing the antifouling back into direct contact with the water also prevents the formation of barnacles and “dog teeth” .
