Benefits of technology

The invention is a maneuvering system for watercraft that allows for better control and comfort. It includes a housing that serves as a buoyancy and hydrodynamic hull extension, and a compact hydraulic drive. The system also has a "go home" emergency function in case of main engine failure. The positioning of the housing close to the stern end improves the torque effect during maneuvering, and the bottom of the housing has levels to improve hydrodynamics. The entire assembly can be mounted in a vibration-damped manner on the stern, thus transmitting less noise and vibrations to the watercraft. The maneuvering system reduces consumption and improves efficiency of the watercraft.

Problems solved by technology

The increasing desire on the part of skippers to also approach port facilities laterally and maneuver into parking gaps in this way is technically feasible with a bow-and-stern rudder but is tedious for the operator and requires appropriate practice.

Embodiment Construction

[0010]The object of the invention is to provide a maneuvering system for a watercraft with rigid drive, stern-drive, outboard engine or jet drive which has the function of a bow thrust rudder or stern thrust rudder, namely to enable lateral driving or rotating of the watercraft about the vertical axis, but without a tunnel in the bow, as well as easier operation for greater comfort and increased safety, as well as substantially easier maneuverability even with swivelable stern-drives, because the thrust forces act further outside on the hull. It is also advantageous that the maneuvering tasks can also be carried out with a single main engine. Furthermore, the maneuvering system has a “go home” emergency function as a drive in the event that the main engines fail. A housing carries and protects the maneuvering system and serves simultaneously as buoyancy means and hydrodynamic hull extension.

[0011]The system is controlled conventionally by means of the steering wheel and the throttle...

Abstract

The invention relates to two maneuvering systems (5), each of which is located in a housing (11) and which are placed as far apart from each other as possible on the stern (10) in order to this enable a watercraft to be moved precisely on the longitudinal axis (LA), laterally, forward / backward and on the vertical axis (HA). By means of a modified throttle and gear lever of the main engines (2), referred to as a manipulator (8), which is coupled with the functions of the maneuvering systems (5) and, with the integration of the steering wheel (7), all of the maneuvering functions and driving modes can be carried out and automated or act in a supportive capacity by means of the controller (9), or the manual incorporation of the main engines (2) can be permitted at any time by means of an actuator (25b).

Description

TECHNICAL FIELD[0001]The invention relates to a maneuvering system for watercraft according to the preamble of the first claim.PRIOR ART[0002]Maneuvering means such as lateral thrust rudders in the form of freestanding propellers or propellers in a tube, centrifugal pumps or jet systems in the bow and in the area of the stern are appropriately known. Their task as simple and efficient course-correction measures or maneuvering aids is to enable a watercraft to rapidly rotate the bow or the stern in an appropriate direction or travel sideways, particularly when maneuvering in narrow ports, in crosswinds or when passing through locks.[0003]Moreover, the shottle drive is known as a stern-drive that can rotate up to 360°, as well as the azimuth drives, which can be rotated 360° as housings.[0004]In recent years, new systems have appeared on the market, particularly by Volvo Penta with the IPS as described in the patent US 2007137550 (A1) and Mercury Marine with the Zeus System, in which ...
