Abstract

The invention discloses a planing boat with a catamaran three-channel hull. The planing boat is provided with a hull and a board at least. The bottom of the hull is provided with an A trunk bulkhead end surface, a B trunk bulkhead end surface, an A slideway, a B slideway, a C slideway, an A planing surface and a B planing surface; the B slideway is arranged along a central line and is a sector structure; the A planing surface and the B planing surface are arranged at two sides of the B slideway; the A slideway is arranged between the A planing surface and a right trunk bulkhead which is provided with the A trunk bulkhead end surface at the stern; and the C slideway is arranged between the B planing surface and a left trunk bulkhead which is provided with the B trunk bulkhead end surface at the stern. The catamaran three-channel hull adopts oval channel section conformation to solve the concentrative stress problem of the hull effectively.simultaneously, on the basis of common channel planing boats, the invention adds two outer side channels at two sides of the stern and changes single channel type into three-channel type, thus greatly increasing the width of the stern, not only improving the effective use area of the board, but also enhancing the transversal stability of the planing boat and being capable of reducing the wave making of the boat.

Description

technical field [0001] The invention relates to a hull structure of a planing boat, more particularly, a planing boat with a double-body three-slot hull suitable for navigating in shallow waters and near-shore areas. Background technique [0002] Ships can be divided into displacement ships, transition ships, planing boats, hydrofoil boats, hovercraft, etc. according to the sailing state and the position of the hull relative to the water surface. [0003] A planing boat is a surface-type ship that uses various principles of hydrodynamic or aerodynamic forces to change the hydrodynamic components supporting the hull. When sailing at low speed (Froude number is less than 1.0), the hull is in a displacement sailing state or in a transitional state. When sailing (Froude number is greater than or equal to 1.0), the entire hull is lifted, only a small part of the hull surface is in contact with the water, the static buoyancy is very small, and the hull is almost completely support...
