Definitions

• a hovercraft motorboat also known as a static air-cushion vehicle or ACV
• ACV is an amphibious boat capable of travelling over land, water, mud, ice, swamps and other surfaces.
• Hovercraft uses blowers to produce a large volume of air cushion below the hull that has pressure slightly above the atmospheric pressure. The pressure difference between the higher-pressure air below the hull and the ambient air with the lower-pressure above produces lift which causes the hull to float above the running surface.
• the air is typically blown through slots or holes around the outside of a disk- or oval-shaped platform, giving most hovercrafts a characteristic shape.
• this static air cushion is contained within a flexible "skirt", which allows the vehicle to travel over small obstructions without damage.
• Hybrid in the dictionary is defined as the offspring of two animals or plants of different races, breeds, varieties, species etc, i.e. the mule is a hybrid offspring from a horse and a donkey.
• the Aquacab (1) Boat invention is the hybrid offspring between a flying aircraft with detachable wings (Fig.2) and a conventional catamaran boat (Fig 3). Hybrid motor boats are not designed often.
• Aquacab hybrid boat assembly (1) primary design purpose is to minimize water friction in order to be able to travel economically, faster, safer and with less C02 emissions, than any other boat in its class, comparing the fuel used over the distance traveled.
• aero-module (2) in Fig. 2 and the aqua-module (11) in Fig. 3 are disengaged from the Aquacab assembly (1) in Fig. 1, they can be used separately, as a normal aircraft and as a normal catamaran boat.
• the said aero-module (2) and the said aqua-module (11) can be utilized independently or as a combination of the two and are able to be joined together as one unit, creating the hybrid Utility Boat - Aquacab (1) in Fig. 1.
• the hybrid utility boat - Aquacab (1) is adapted is such a way that is able to encompass additional detachable secondary-modules assemblies, in order to be able to transport loads, over land, in contact with the water surface as well as over the water surface, taking advantage of the ground effect static and aerodynamic air cushion phenomenon, as described in claims from 1 to 14.
• Each of the Aquacab Hybrid Utility Boat (1) configurations are modular and may be utilized independently or as a combination of two or more modules, joined together securely as an assembly, creating the Hybrid Utility Boat Aquacab (1) capable to operate in land, in swamps, at various sea state conditions and in whiteriver waters at various speeds, as required.
• the Aquacab hybrid boat (1) has a modern boat design with several modular options available and multiuse adaptable operational capabilities.
• the benefits of the Aquacab Hybrid Utility Boat (1) invention, as described in claims from 1 to 14, are many.
• Fig 1 is a perspective view of a basic Aquacab Hybrid Utility Boat (1) invention showing the aero-module (2) and aqua-module (11) as well as the lower ground effect wing set (42, 43) combined as one unit.

• Fig.3 is a perspective view of the catamaran boat called aqua-module (11) of the Aquacab Hybrid Utility Boat (1) with the additional optional modules of the inflatable or rigid floats (23, 24) in the extended position, the removable bow cargo box & air duct module (28), the removable stern / rear section (34), as well as the canard control surface (44) that is connected with the aero module (2) and provides more effective pitch up or pitch down dynamic ground effect control.
• Fig.4 is a perspective view of the load bearing assembly of the aqua-module (11) of the Aquacab Hybrid Utility Boat (1) with the additional optional modules of the retractable wheels (18, 19) as well as the telescopic towing bar (20) and the aerodynamic load bearing assembly cover (21).
• the main supporting longitudinal keel beams (12, 13, 14) and the lateral frames (15, 16, 17) that are one of the main load bearing assembly components that are visible when the aerodynamic cover (21) is removed.
• Fig. 5 is a perspective view of the Aquacab Hybrid Utility Boat (1) invention with the catamaran floats (23, 24) attached in the retracted position and installed in the supporting longitudinal keel beams (12, 13, 14) through the lateral frames (15, 16, 17) and all combined together, form the primary load trailer assembly in a conventional catamaran boat mode with the floats retracted with the aerodynamic cover (21) removed.
• Fig. 6 is a perspective view of the bow section box and air duct module (28) of the Aquacab Hybrid Utility Boat (1) invention inside where the hovercraft lift fan (41) is fixed.
• the hovercraft lift fan (41) is fixed and connected with the optional aqua-engine module (29).
• the bow section box and air duct module (28) is attached through the longitudinal beams (12, 14) with the load bearing assembly (Fig. 4).
• the optional inboard aqua-engine module (29) is connected with at least one gearbox (30) with at least one retractable sea long tail shaft (31) with sea propeller(32) and sea rudder (33) assembly that is attached or adapted to have attached together and powers the Aquacab Hybrid Utility Boat (1) in order to transport various loads over water.
