The invention relates to a speed boat. The speed boat comprises a boat body and an engine room ventilation system; the engine room ventilation system comprises two ventilation units which are symmetrically arranged on two sides of the boat body; each ventilation unit sequentially comprises an inlet, a moisture separating device and an outlet along a fluid advancing direction; the inlets are formed in an engine room deck; openings of the inlets are towards a boat bow; the length direction of the moisture separating device is arranged along the length direction of the boat body; each ventilation unit also comprises a drainage device and a settling device which is arranged at the upstream of the corresponding moisture separating device; each drainage device comprises a collector and a drainage opening which is communicated with the collector; each collector comprises a bottom surface of a fluid channel of the moisture separating device and a bottom surface of a chamber; each drainage opening is formed in the external lateral side of a board side; the outlets comprise air outlets of the fluid channels and the drainage openings of the drainage devices. Compared with the existing speed boat, air resistance generated by the engine room ventilation system of the speed boat to the boat body is relative small and improvement of the navigational speed of the speed boar is facilitated.
