The invention relates to an environment electric spray-propelled vessel, comprising a course adjustment control device that comprises a course changing sleeve, swing plates, vertical positioning shafts,
copper sleeve glands, a vertical operating
pipe, a connection rod, and a steering gear sliding rod; the vertical positioning shafts are distributed and fixedly connected to the rear end wall of a
water spray pipe in top-bottom symmetry manner, the swing plates are distributed and fixedly connected to the front end wall of the course change sleeve in top-bottom symmetry manner, the swing plates may rotate around the vertical positioning shafts, the
copper sleeve glands are connected to the swing plates through bolts, the lower end of the vertical operating
pipe is fixedly connected to the upper
copper sleeve gland, the upper end of the vertical operating pipe is movably connected to the connection rod, the connection rod is movably connected to the steering gear sliding rod, a steering gear is operated to drive the course change sleeve to rotate around the vertical positioning shafts, and the course of the vessel is controlled. The course adjustment control device is simple in structure, flexible to operate and practical and reliable. The environment electric spray-propelled vessel acting as a yacht is free of
pollution and low in
noise, never catches a net or wraps a
propeller, or sucks to a
bed or strands on a beach when acting as an
aquaculture vessel and
fishing vessel, and is convenient and quick to use and low in cost when acting as a ferry.
