A rudder device is disclosed for a hydrojet vessel. The rudder device comprises a first mounting bracket coupled to a first hydrojet. A first rudder is coupled to the first hydrojet and the first mounting bracket. A second mounting bracket is coupled to a second hydrojet. A second rudder is coupled to the second hydrojet and the second mounting bracket. A coupling rod is pivotably coupled to the first hydrojet, the second hydrojet and a hull rudder for pivoting in alignment and in unison the first rudder with the first hydrojet and the second rudder with the second hydrojet relative to the hull rudder. The first rudder and the second rudder provide steerage to the vessel during non directional thrust absent from the first hydrojet and the second hydrojet.

A marine vessel includes a distance detector that measures a distance to an object, a speed detector that detects a vessel speed, and a controller that executes on-shore/off-shore assistance control to control a propulsion unit to generate a thrust that moves a vessel body in a direction opposite to a direction toward the object based on the distance to the object measured by the distance detector and the vessel speed detected by the speed detector.

A propulsion device includes a platform which provides support for a passenger. The platform comprises an upper surface and a lower surface, and cooperates with means for collecting and distributing a pressurized fluid to a primary nozzle expelling the fluid from a fluid outlet in a fluid expulsion direction. The means are supplied with pressurized fluid by a fluid supply conduit. The primary nozzle is oriented substantially from the bow to the stern of the platform. The fluid expulsion direction of the primary nozzle is located in a median plane of the platform. The fluid expulsion direction of the primary nozzle describes defines an angle comprised between 10 and +45 with a longitudinal axis of the platform contained in the median plane. The means for collecting and distributing a fluid cooperate with the platform by an embedding link.

A jet propulsion boat includes a boat body, an operation part operated by a driver on the boat body, a turning posture detector that detects a turning posture of the boat body when a driver performs operation of turning the boat body, a behavior adjustment actuator that adjusts a behavior of the boat body, and a controller that controls the behavior adjustment actuator based on the turning posture detected by the turning posture detector.

A propulsion device including a platform on which a passenger is positioned, said platform comprising an upper surface and a lower surface, and cooperating with means for collecting and distributing a pressurized fluid to a primary nozzle expelling said fluid from a fluid outlet in a given direction, said means being supplied with pressurized fluid by a fluid supply conduit, the device being characterized in that: the primary nozzle is oriented substantially from the bow to the stern of the platform; the fluid expulsion direction fits in a median plane of the platform; the fluid expulsion direction of the primary nozzle describes an angle comprised between 10 and +45 with a longitudinal axis of the platform contained in said median plane.

A system for controlling a marine vessel having first and second steering nozzles and corresponding first and second reversing buckets, comprises a processor configured to receive a first vessel control signal including at least a component corresponding to a translational thrust command in a port direction, and that is configured to provide a set of actuator control signals coupled to and control the first and second reversing buckets. The processor is configured to provide the set of actuator control signals so as to maintain the first reversing bucket substantially in a first discrete position and the second reversing bucket substantially in a second discrete position as long as the first vessel control signal includes a component corresponding to a translational thrust command in the port direction.

A jet propulsion boat includes a propulsion device configured to generate a jet of water, a first discharge portion provided in a rear portion of a boat body, including a first discharge port from which the jet of water is discharged, a second discharge portion including a second discharge port from which the jet of water is discharged, configured to be rotatable so as to change the discharge direction of the second discharge port, and a jet path configured to connect the propulsion device to the first discharge portion and the second discharge portion.

The present invention relates broadly to a floating structure and more particular to a floating structure formed by a plurality of modular floating units, a method for forming a floating structure, and a method for stabilizing a plurality of modular floating units line abreast. The method for forming a floating structure comprises providing a plurality of modular floating units including three of more tunnel thrusters; aligning the plurality of modular floating units wherein each of the three or more tunnel thrusters of each of the plurality of modular floating units are aligned to each of a corresponding three or more tunnel thrusters on an adjacent modular floating unit; and operating at least one of the three or more tunnel thrusters of each of the plurality of modular floating units to generate at least one horizontal pillar of water flow, wherein the at least one horizontal pillar of water flow skewers each of the plurality of modular floating units longitudinally through one of the three or more tunnel thrusters thereof.
