The invention relates to the technical field of high-speed boat types, in particular to a novel flat-head longitudinal-flow inland river high-speed boat type with a large block coefficient. The novel flat-head longitudinal-flow inland river high-speed boat type comprises a boat body, and the boat body comprises a keel, a boat bottom, a side plate, a deck, a stern transom plate and a bow transom plate. The cross section of the boat body is in U-type design. The boat body is in streamlined design in the longitudinal direction, and the block coefficient is about 0.5 to 0.8. A stern is in flat head design. The cross section of the position, in front of a midship, of the boat bottom is in arc-shaped design, and the oblique ascension angle is about 5 degrees to 20 degrees. The cross section of the position, behind the midship, of the boat bottom is in V-type design, and the oblique ascension angle is about 5 degrees to 20 degrees. The front end and the tail end of the boat bottom are in smooth transition. The boat type is suitable for high-speed navigation in shallow water, can meet foreshore pull-over needs and has good maneuverability in vortexes and underflow of inland rivers.
