ABSTRACT:
A vessel travels over a surface of a body of water or a waterway to collect waste on and/or close to the surface. A retainer that traps and retains the waste is activated by creating a water flow channel that is connected to a water inlet and a water outlet on the vessel. The retainer is on at least one trajectory of said channel. Waste is collected without using a specific pumping or gathering device.
