Underwater hull cleaning

Cleaning the underwater hull is one of the most important maintenance tasks for any boat — but it’s not always easy. The underwater hull is the part of the boat below the waterline, which means it’s constantly exposed to underwater conditions such as currents, salt, dirt, and marine growth.

Why Cleaning the Underwater Hull Matters

Typical buildup on the underwater hull includes algae, slime, and especially barnacles and mussels. Hard growth like shells significantly increases drag and reduces the boat’s glide and overall performance. The result: higher fuel consumption, noticeable loss of speed, and increased strain on the hull, engine, and drivetrain.

Protective coatings such as antifouling paint can help reduce fouling, but they don’t solve the problem completely. That’s why you should clean the underwater hull regularly using mechanical methods. In most cases, this means the boat needs to be taken out of the water so the hull can be cleaned thoroughly and safely.

Clean the Underwater Hull Without Harming the Environment

Besides algae and shell growth, the underwater hull can also collect stubborn residues like oil, tar, and other deposits. These contaminants can’t be removed quickly with just water and a sponge. For this reason, many people use high-pressure washers, chemical cleaners, or even strong acids — often without realizing the environmental impact or the potential damage to hull surfaces and coatings.

The Eco-Friendly Solution by systeco

At systeco, we developed an alternative: a cleaning machine that allows you to clean the underwater hull completely without water or chemicals. systeco cleaning systems work in an environmentally neutral way and are particularly gentle on surfaces because they avoid aggressive agents and unnecessary abrasion.
