Benefits of technology

The present invention provides a vessel that can produce propulsive force in any direction. This allows for greater flexibility and efficiency in the movement of the vessel.

Problems solved by technology

However, no vessel is disclosed which includes Arneson Surface Drives whose right and left propellers are controlled independently of each other in order to obtain propulsive force in an arbitrary direction.

Embodiment Construction

[0013]The configuration of a vessel 100 will be described with reference to FIG. 1.

[0014]In FIG. 1, for the sake of easy understanding, a hull 10 is illustrated in a see-through manner. In the following description, front-back and right-left directions are determined assuming that a bow of the vessel 100 is a front of the vessel.

[0015]The vessel 100 is an embodiment regarding a vessel according to the present invention. The vessel 100 according to the present embodiment is a vessel with a twin-screw propulsion system including only two Arneson Surface Drives 40. The vessel 100 includes the hull 10, two engines 20, two switching clutches 30, the two Arneson Surface Drives 40, and a vessel steering device S.

[0016]The engine 20 rotates a propeller 44 provided on the port side or the starboard side. The engine 20 is disposed on each of the rear port side and the rear starboard side of the hull 10. The switching clutch 30 is connected to an output shaft of each engine 20.

[0017]The engine...

Abstract

The purpose of the present invention is to provide a boat capable of obtaining a propulsion force in a discretionary direction. A boat is provided with Arneson drives which drive propellers by means of propeller shafts via universal joints, and which control the left and right directions of the propellers by means of hydraulic cylinders. Two of the Arneson drives are provided, and the Arneson drives are respectively provided to the left and right sides of a hull. The propellers are controlled in the left and right directions in a mutually independent manner.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This is the U.S. national stage of application No. PCT / JP2016 / 055857, filed on Feb. 26, 2016. Priority under 35 U.S.C. § 119(a) and 35 U.S.C. § 365(b) is claimed from Japanese Application No. 2015-042797, filed on Mar. 4, 2015, the disclosures of which are also incorporated herein by reference.TECHNICAL FIELD[0002]The present invention relates to a technique regarding a vessel.BACKGROUND ART[0003]Conventionally, a technique of an Arneson Surface Drive for a vessel is known. The Arneson Surface Drive is a drive system that drives a propeller by a propeller shaft via a universal joint and controls the vertical and horizontal directions of the propeller by a hydraulic cylinder (for example, Patent Document 1).[0004]In addition, a vessel is known in which only two right and left Arneson Surface Drives are disposed and propellers are controlled in the horizontal direction to steer the vessel. In such a vessel, right and left propellers are int...
