Problems solved by technology

So far, water jets have been installed on conventional surface effect boats, but there have been some difficulties in avoiding air leakage from the air cushion to the water jets, which would lead to reduced pump efficiency and cavitation damage, as well as due to Damage to the main engine due to load changes

Embodiment Construction

[0041] Figure 1 presents the invention and provides a brief description of the invention. It shows a perspective view of a catamaran (1) with an asymmetrical hovering hull 2 ​​combined with a propelling hull 3 located inboard, as described below.

[0042] According to the above argument and FIG. 1 , the present invention consists in the original construction of a catamaran - catamaran ( 1 ) - with an asymmetrical monohull hull 200 with a generally flat inner side 31 . Each monohull comprises a front section 8 consisting of one or more planing surfaces and / or displacement sections which individually or together generate dynamic lift at high speeds, And generate hydrostatic lift at low speed and at rest. The lowest surfaces meet at the bottom of the boundary line 4 which forms the shape of the bow stem and lies on a vertical plane parallel to the plane 201 of the centerline of the vessel.

[0043] Any transverse section through the bow of the lowest part of the hull surface sh...

Abstract

The present invention includes a hull supported by a combination of static air pressure (a cushion of air), dynamic lift (planing hull sections), and aerodynamic ram effects (in multi-hull applications) that combine with additional hull sections (some of which are used for planing and some for displacement), the additional hull sections are designed to improve the stability, advancement and seaworthiness of the vessel, and are designed to accommodate efficient propulsion means, and are designed to reduce the resistance of the vessel in still water and in waves. The idea of ​​the present invention can be used on monohull vessels and several multihull vessels described below to achieve relatively high speeds.
