The invention provides a high-speed boat angle-variable wave suppression device combined with a surface propeller. The high-speed boat angle-variable wave suppression device combined with the surface propeller comprises a hydraulic pushing rod, a rotary shaft, a wave suppression plate, a motor and the like, wherein the wave suppression plate is installed above the surface propeller and fixed to the lower edge of a stern ramp, and the included angle between the wave suppression plate and the stern ramp is adjustable. The high-speed boat angle-variable wave suppression device combined with the surface propeller is mainly used for intercepting sprays and wave rising from the back of a ship during work of the surface propeller. The high-speed boat angle-variable wave suppression device combined with the surface propeller has the significance of improving the stealth performance of the high-speed boat, reducing the pressure difference resistance, achieving the purpose of reducing resistance, adjusting the posture of the high-speed boat, improving movement stability and bringing convenience to back up. The high-speed boat angle-variable wave suppression device combined with the surface propeller is compact in structure, low in cost, high in controllability and mainly used for the high-speed boat driven by the surface propeller.
