A method for providing a hull of a vessel with bubble generators

A method for providing a hull of a vessel with bubble generators for reducing the drag of the hull, wherein said method comprises the following steps:

• providing at least one elongated slot in the hull, said slot having a length extending in a lateral direction of the vessel and a width extending perpendicular thereto;
• providing a multitude of bubble generator units, each of said multitude of bubble generator units having an inlet opening for supplying air and a bottom surface with at least one outlet opening for discharging air bubbles;
• and
• mounting said multitude of bubble generator units in said slot in a side by side manner along the length of said slot such that said slot is filled and substantially closed off by said bubble generator units, and such that said inlet openings of said bubble generator units face the interior of the hull and the bottom surfaces with the outlet openings of said bubble generator units face the exterior of the hull.
