    摘要: A draining arrangement of a propulsion unit of a marine vessel. The propulsion unit includes a shell structure. The shell structure limiting at least one bottom section configured to receive liquids. The draining arrangement including a pneumatically operated drainage arrangement including an intermediate tank within the shell structure, a pressurizing arrangement functionally connected to the intermediate tank and configured to selectively provide a vacuum in the intermediate tank or an excess pressure in the intermediate tank, a first liquid line that is provided between the intermediate tank and said at least one bottom section, and a second liquid to line that is provided between the intermediate tank and a collector arrangement within the hull of the marine vessel.

    摘要: A thruster assembly to create shaped waves in a water behind a boat for water sports, such as wake surfing. The thruster assembly comprises one or more thrusting channels, an outer body the outer body comprises a round surface in the form of a circular or elliptical cross-section. The outer body comprises an elongated elliptical cross-section being wider than it is tall. A thruster portion comprises a width, a height, and a depth. The outer body comprises an outer surface and an inner surface. The outer body comprises a round surface in the form of a circular or elliptical cross-section. The outer body comprises an elongated elliptical cross-section being wider than it is tall.

    摘要: An aeration control system and method for a marine vessel. The system includes a valve configured to be coupled to an aeration conduit of a marine vessel. The valve is configured to be responsive to a valve control signal having a first value so as to be open and to provide air to the aeration conduit, and the valve configured to be responsive to the valve control signal having a second value so as to be closed and not provide air to the aeration conduit. The aeration control system also includes a control device, electrically coupled to the valve, that provides the valve control signal to the valve

    摘要: A foot controller system includes a foot controller having a base that engages a portion of a marine vessel when the foot controller is in an operable position. The foot controller also includes a foot pedal pivotable, with respect to the base, about a first axis, and rotatable, with respect to at least a portion of the base, about a second axis different from the first axis. The foot controller controls a first aspect of a marine motor system when the foot pedal is pivoted about the first axis and controls a second aspect of the marine motor system different from the first aspect when the foot pedal is rotated about the second axis.

    摘要: A marine plant assembly comprising a floating vessel and a plant operating unit attached to a buoyancy vessel in such a way that the operating unit is at least partially submerged during operation. At least one link element provides a hinged connection between the operating unit and the buoyancy vessel, thereby to allow movement of the operating unit from its submerged operating position to above the water level and adjacent the buoyancy vessel by said link element rotating into a position substantially parallel to the buoyancy vessel.

    摘要: An assembly for a retractable thruster suitable for attachment to the hull of a maritime vessel. The assembly comprises a thruster accommodating structure from which the thruster may be deployed into and retracted from the water. The thruster accommodating structure is provided with a drive assembly that suspends the thruster and further comprises a thruster deploying and retracting device, a thruster rotating device, a motor assembly, and a switching device. The same drive assembly is used for deploying, retracting, and rotating the thruster.
