A vessel braking control system for a marine vessel that utilizes one or more of the vessel's features and effectors to increase the drag on the vessel both through increased drag on the features and effectors themselves and by creating a downward force on the vessel as a whole, increasing the wetted hull area and increasing hull drag thereby; the control system operates to place the features and effectors in a braking state through rotation relative to the vessel's direction of travel and relative to the water's surface, and may automatically return the features and effectors to their normal operating state upon the vessel's reaching a detected, predetermined speed.

A submersible vessel comprising: an elongated hull; at least one propeller mounted on a forward end of said hull and adapted to move said hull through water; said at least one propeller being of a size and configuration such that when it is rotated at an appropriate speed, it generates supercavitated water flowing from said at least one propeller and thence along an outer surface of said hull so as to diminish friction on the outer surface of said hull and facilitate high underwater speeds.

There is provided systems and methods for stabilising a vessel against a stationary structure. Embodiments of the system include a sensor system, a processor, and a vessel control system. The processor is configured to determine a change in the position and/or motion of the waterborne vessel relative to the stationary structure based on sensor data, and to determine a minimum corrective force required to oppose the change. The minimum corrective force is then delivered by the vessel control system operable to stabilise the waterborne vessel relative to the stationary structure.

A support system for outboard marine motors at the transom of a boat includes a support device having a first part that is integral with the transom and a second part that is integral with the outboard motor. The second part is translatable with respect to the first part, so that the second part moves according to an orientation in the distancing or approaching direction of the water line of the boat. A control unit is configured to set the position of the second part with respect to the first part and to generate control signals, so as to move the second part in the direction of immersion of the propeller of the outboard motor.

A method and a system for controlling a marine vessel having first and second trim deflectors is disclosed. The first and second trim deflectors have a first surface having a first area and a second surface having a second area, wherein the second planar surface is coupled to the first surface. The method and system control the first and second trim deflectors to induce any of a net yawing force, a net rolling force, and a net trimming force to the marine vessel without inducing any other substantial forces to the marine vessel by controlling the first and second trim deflectors.
