<p>The water craft of this invention is capable of efficiently reducing the level of aquatic plant infestation of waterways by mulching or otherwise finely chopping plants growing on the surface of the waterway as the water craft moves through the water. Preferably, the water craft is capable of rapidly moving through plant infested waters while rapidly mulching the infesting plants. In one embodiment, the water craft is a boat equipped with an intake port (1) and an exhaust port (2), with at least one and preferably several arrays (8) of cutting blades disposed between said intake and said exhaust ports such that any solid matter is mulched or cut into tiny pieces upon passage from said intake port on its way to said exhaust port, said intake port being disposed so as to allow plant infested water to enter the boat and come into contact with said array or arrays of cutting blades.</p> |
