ABSTRACT:
An airboat having aquatic vegetation shredder includes an airboat having a buoyant hull and an aquatic vegetation shredding assembly supported on the hull. The airboat is driven by a propulsion assembly including a propeller that revolves in the air. These features cooperatively provide a low draft vessel that is capable of relatively higher forward speeds than other aquatic vegetation shredders and particularly effective in shallow water environments. Various alternative configurations of the shredding assembly are disclosed including upright and fore-and-aft shaft orientations for the cutting assembly and a drum and knife cutting assembly.
