In Panama Aquadiver team divers for Hull, cleaning use Special Twin Hydraulic Brushes to remove any kind of marine grows from vessels, have used special brushes in contact with the hull surface removing all fouling layer to remove fouling. The material of the brush can be different and depends on marine grow attached
 Different kind of brushes materials is also used on the different hull as nylon or
plastic, Stanley steel brushes are an example
Other methods of removal include: rotating  brushes that create centrifugal force
over the hull surface without touching it, high-pressure with hydraulic power packs powered
These methods are intended to reduce the friction effects of marine grow on antifouling coatings,
