The invention discloses an anti-splash single-hull planing boat which comprises a boat body, a propelling device and a composite stabilizing wing, wherein the composite stabilizing wing is arranged at the bottom of a stem; the composite stabilizing wing comprises a vertical stabilizing wing and a horizontal stabilizing wing; downwardly inclined longitudinal anti-splash bodies are symmetrically arranged on two sides of the boat body from the front bilge part of a boat middle part to a stem bilge part; the widths of the longitudinal anti-splash bodies are gradually narrowed from the front part of the boat middle part to the stem; the head part of the boat body is gradually transitional from a shallow V-shaped cross section with an acute angle between the two side surfaces to the shallow V-shaped cross section with an obtuse angle between two side surfaces of the front part of the boat middle part; and the front part of the boat middle part is gradually transitional from a shallow V-shaped cross section with an obtuse angle between two side surfaces to a horizontal cross section, on which V-shaped edge strips extend downwards from two sides of the bottom of the stem, or an inverted shallow V-shaped cross section with an obtuse angle between two side surfaces. According to the invention, the splashing of lateral water flow of the sliding surface of the boat body can be effectively prevented, so that the rapidness, transverse stability, longitudinal stability, directional stability, seakeeping quality and so on are greatly improved, convenience for mounting propellers with larger diameters is achieved, and the propelling efficiency is increased.
