In various embodiments, a wake diversion system operates to manipulate the characteristics of the stern waves produced by a watercraft as it passes through water. In one embodiment, the wake diversion system includes a wake diverter that is comprised of a body, a panel, and a plurality of boat attachment mechanisms. The wake diverter is removably attachable to the side of the hull of a watercraft such that it obstructs the natural flow of water around the hull of the watercraft on side of the watercraft to which it is attached.

An extendable hull system movable between a mono-hull to a multi-hull configuration is provided so as to take advantage of both types of hull designs depending on the boating conditions. The extendable hull system provides a center hull portion and two side hull portions, each with separate planing surfaces in an expanded multi-hull configuration, and providing a shared planing surface in the contracted mono-hull configuration. The extendable hull system provides a pivotably connected railing system along a periphery of the side hull portions for moving to a deployed configuration providing additional walking surface. The extendable hull system provides a retractable awning movable between positions for covering the mono-hull and the multi-hull configuration.

A control system for posture control tabs of a marine vessel prevents posture control tabs from coming into contact with a foreign object. The posture control tabs are mounted on a stern to control a posture of a hull. Actuators actuate the respective posture control tabs. When it is judged that that the hull is being loaded onto a trailer or it is detected that the hull has entered a speed restriction zone, a controller controls the actuators to position the posture control tabs at retracted positions.

Device for controlling the trim of a boat including at least one trim tab element or the like, engaged to the transom of the boat by a hinge. At least one actuator is also provided, which is affixed to the transom by an upper terminal and to the tab by a lower terminal respectively through an upper joint and a lower joint. The lower joint includes at least two parts, of which a first part is connected to the lower terminal of the actuator and a second part includes a lower bracket affixed to the tab by fastener means, which are engaged in corresponding engagement seats on the lower bracket and the tab. The first part includes a terminal element, which is provided in a housing seat formed on the lower bracket, such to enable a relative movement of actuator and tab with at least two degrees of freedom.

A fluid hinge includes a first part of a two-part element including a planar surface of a trim tab and a second part of the two-part system having at least one bracket secured to the hull of a watercraft and the first and second parts of the two-part element are not physically coupled together. It also provides at least one bracket secured to the hull on which the planar surface of the trim tab may rest and the at least one bracket not taking any load from the planar surface except at rest to keep the planar surface from descending below the horizon of the hull.

A planing system for a multi-hull watercraft comprising a hull defining a plurality of hulls and at least one channel between at least two of the hull portions comprises a planing surface and an actuator system. The planing surface is supported for movement within the at least one channel between an upper position and a lower position. The actuator system is arranged to displace the planing surface from the upper position to the lower position. The watercraft operates in a first mode when the planing surface is in the upper position and in a second mode when the planing surface is in the lower position. When the watercraft operates in the second mode, the planing surface engages water to cause the vessel to plane.
