Inflatable motor boat with motor mount

Abstract

An inflatable boat with a motor mount for use in shallow water conditions. The inflatable boat with the motor mount has a U-shaped hull in plan view, which is formed by open outline of inflatable boards and nose, as well as a transom installed on the boat stern and an inflatable bottom attached to the hull from below, and which bottom has an axissymmetric groove laying longitudinally from the stern end. The groove is V-shaped in cross-section. The depth of the groove is reduced uniformly in direction to the bottom nose. The inflatable boat according to the present invention allows expansion of usage specifications of the inflatable boats with motor mount, provides an additional guard for the outboard motors installed on them against possible mechanical damages and lowers fuel consumption in comparison with the boats of similar design.

Claims

1. The inflatable boat with motor mount, comprising: a U-shaped hull in plan view, wherein the hull is formed by open outline of inflatable boards and a nose, and a transom mounted on a boat stern and an inflatable bottom attached to the hull from below, the bottom having an axisymmetric groove laying longitudinally from a stern end; wherein the groove is V-shaped in cross-section, wherein the depth of the groove is reduced uniformly in direction of the hull nose, wherein the length of the groove is from 5 to 20% of the length of the boat bottom, an angle of a groove inclined plane is about 30, wherein an angle of groove lateral sides are about 45 relative to a vertical plane.

2. The inflatable boat with motor mount according to claim 1, wherein width of the groove at the stern end is 20 to 60 cm.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) The present invention will become more fully understood from the detailed description given hereinbelow and the accompanying drawings which are given by way of illustration only, and thus, are not limitative of the present invention, and wherein:

(2) FIG. 1 shows longitudinal vertical section of the boat with outboard motor mount installed, side view; and

(3) FIG. 2 shows the boat stern rear view.

DETAILED DESCRIPTION

(4) FIG. 1 illustrates an embodiment of the present invention where an inflatable boat with motor mount contains a hull 1, an inflatable bottom 2 with groove 3 and a transom 4 with outboard motor 5 with water propeller 6 installed on it.

(5) The groove 3 in the inflatable bottom 2 provides for water flowing upward with certain angle while the boat is moving, thus water is flowing in the required amount directly to the propeller 6 of the outboard motor 5 secured to the transom 4. This enables using of motors with a shorter leg and arrangement of the propeller 6 closer to the water surface above the stern draft of the boat itself. Meanwhile, the general draft of the vessel is reduced, that enables using hereof on shallows, in low water conditions, etc. Moreover, the hull 1 and the bottom 2 of the inflatable boat serve as a guard for the propeller 6 arranged behind and a bit higher, against possible mechanical damages caused by rocks, sunken wood and other stock under water.

(6) The boats with declared geometric dimensions of the groove 3 have demonstrated 3% lower fuel consumption relative to the boats with geometric dimensions of the groove designed beyond the declared ranges.

(7) The boat according to the disclosed embodiment of the present invention allows expansion of usage specifications of the inflatable boats with motor mount, provides an additional guard for the outboard motors installed on them against possible mechanical damages and lowers fuel consumption.
