A port-hole of an immersed structure, for seeing, from inside the structure in air, to the outside of the structure in water, level with the structure, wherein the face of the port-hole oriented toward the inside of the structure includes at least one flat section forming an angle of 20 to 40° with respect to the face of the port-hole oriented toward the outside of the structure.

A retractable windshield for a boat includes a main windshield section having a closed configuration in which the main windshield section is substantially vertically oriented in front of a driving position within the center console and an open configuration in which the main windshield section is substantially horizontally oriented above the driving position and adjacent to the rooftop. The main windshield section is configured to rotationally transition from the closed configuration to the open configuration in response to a force applied to a bottom portion of the main windshield section in a direction away from the driving position and upward.

An electronically powered window for a watercraft consists of a shuttle frame, a sliding mechanism, a window pane, and a bottom edge support groove. A first lateral support arm and a second lateral support arm of the shuttle frame along with the bottom edge support groove helps position the window pane within the shuttle frame. The sliding mechanism allows the user to position the window pane such that the window is in an open configuration or a closed configuration. To do so, a first lateral edge is slidably positioned along the first lateral support arm. Moreover, a second lateral edge is slidably positioned along the second lateral support arm.

It relates to an urban craft, which belongs to the industrial sector of nautical vehicles for transportation of crew and passengers in general, composed of a speedboat (1) equipped with a central cab (2), a transparent roof (3), a honeycomb grid (4), an X-shaped structure (5), faceted areas (6), a catamaran hull (7), an inverted nose (8), a negative bow (9), engines (10), a propeller (11), seats (12), safety belts, airbags, acceleration and braking pedals (13), a steering wheel (14), a dashboard (15), a central console (16), a gear shift lever (17), armrests (18), cupholders (19), internet/Wi-Fi access, detachable tablets (20), a lateral boarding platform (21), headlights (22) and lateral arrows in the camera-based rearview mirrors (23), an air-conditioning system, a pneumatic suspension system with adjustable airbags and hydrogen-based shock absorbers, individual (rear and front) lateral doors (24), large gullwing lateral doors (25), an upper airfoil (26), a rear window (27), a foldable rear platform (28) with a step over the propelling devices (29), a central watershed system (30), a panoramic front window (31), a front hood with luggage compartment and access to fuel supply, a rear camera (32).

There is described a hinge for detachably connecting a door or window to a wall or a frame such as a windshield. The hinge comprising a shaft extending longitudinally, further comprising a blocker which is extendable about the shaft. A first socketed member is fixed to the shaft, and a second socketed member comprises a lumen for sliding the shaft therein. The lumen comprises a cavity larger than a remainder of the lumen and which defines an inward edge on which the blocker abuts, thereby retaining the shaft in the lumen. The shaft comprises an inner recess which can house the blocker therein if the inner recess is aligned with the blocker, thereby retracting the blocker from the cavity and releasing the shaft from the second socketed member and allowing the first socketed member and the second socketed member to be separated. This can be useful for detaching a door of a boat windshield, for example.
