The benefits of Mermaid Marine Services polishing equipment:
The only way to keep a propeller in shape is to ensure a proper and regular cleaning. It is therefore essential to keep the leafs of the propeller's surface smooth and free of marine organisms, because if the surface of the leafs of the propeller's becomes uneven, then the resistance of the water gets higher.
This could end with the emergence of cavitation that constantly intensify itselfs, if one does not keep the surface even by polishing this unevenness with fine diamond discs.
By polishing the blades of the propellers with diamond disks in the water one has achieved to get a smoother surface than even a propeller manufacturer can provide.
