Anti-splash monohull planing boat

Abstract

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.

Description

technical field [0001] The invention relates to a planing boat, in particular to a single-body planing boat capable of carrying people on water and used for transportation, travel and sightseeing, which prevents water flow from splashing sideways on the planing surface, and belongs to the technical field of high-performance ships. Background technique [0002] The planing boat is an important member of the high-performance boat family, especially the single-body planing boat, which is the most widely used and most numerous high-speed boat at home and abroad. The planing boat slides at high speed on the water surface, relying on hydrodynamic force to support most of the weight of the planing boat, and the water buoyancy only supports a small part of the weight of the planing boat. Compared with displacement ships, its advantages are small contact area with the water surface and small resistance. The speed is fast, but the disadvantages are large vibration, severe impact, poor...

AI Technical Summary

Problems solved by technology

The planing boat slides at high speed on the water surface, relying on hydrodynamic force to support most of the weight of the planing boat, and the water buoyancy only supports a small part of the weight of the planing boat. Compared with displacement ships, its advantages are small contact area with the water surface and small resistance. The speed is fast, but the disadvantages are large vibration, severe impact, poor riding comfort, poor heading stability, and strict weight distribution requirements. These shortcomings seriously limit the weight arrangement of the boat. In addition, the lateral water flow on the sliding surface of the planing boat is prone to rapid splashing when sailing at high speed. Phenomenon, which greatly affects the speed, navigation stability and seakeeping performance of the whole boat
