Abstract: Craft including hull having stern with mobile platform having first work position where it is extracted from water, and second work position where it is immersed in water, device for platform movement having a pantograph, a structure with an articulated quadrilateral connected to the mobile platform, said movement and a unit for actuating movement of this structure, which unit allows moving the platform from the first to second work position and vice versa. The structure with articulated quadrilateral folded back onto hull when platform is in first position, and extended when platform is in second position. The movement device includes a body distinct from hull. The structure with articulated quadrilateral integral with, but mobile relative to body. The body secured on hull stern and having at least one fixed step, at least one second step inside the structure with articulated quadrilateral, which step moveable and foldable back with the structure.

Abstract: A vessel or boat includes a hull having a stern at which there is a stern swim platform having at least one moving part capable of moving along and close to a portion of the stern, the moving part being capable of adopting at least a first working position in which it is out of the water on which the boat floats and a second working position in which the moving part is lowered with respect to the hull into the water, steps being provided at the stern. At least part of the steps is of one piece with the moving part of the stern swim platform and moves therewith over fixed steps provided within the stern, the movement of the steps taking place in a guided way, the moving steps forming an elongatable swim ladder with the fixed steps.

Abstract: A boat includes a hull provided with a rear stern hatch located in correspondence with an internal stern compartment of the hull and suitable for opening and closing in correspondence with an aperture of the compartment, the hatch having a body with opposed side located in correspondence with side walls of the compartment and upper edge and lower edge. The hatch includes an actuator to open and close the compartment arranged inside its own body, the actuator rotatably constraining at least one of the sides of the hatch to a support movable with respect to the stern of the hull and suitable for allowing the hatch to reach, upon opening, a position submerged in the water where the boat is, the body of the hatch being not provided with any further connections of the sides to the hull.

Abstract: A watercraft includes a hull provided with a stern compartment inside the hull, the compartment being closed at least on the bottom by a movable portion of a stern platform arranged at one end of the compartment itself which opens up astern of the watercraft, wherein the movable portion can be lowered relative to the hull into the water where the watercraft is floating. The movable portion of the stern platform shifts with a translational motion along the hull without moving away therefrom.

Abstract: A boat includes a hull, a deck and a living area, the latter delimited at the front by a windscreen and having a fixed structure, extending from that area, supporting boat functional members such as antennas and the like, there being a one-piece mobile rigid canopy, moved by moving members and adapted to take at least a first working position in which it is arranged above the living area and at least a second working position in which it is separated from the latter and is associated to the deck in front of the windscreen, the rigid canopy resting on and being constrained to the windscreen and to the fixed structure when it is in its first working position. The moving members are articulated structures placed laterally to the deck.

Abstract: A boat includes a hull having an aft stern hatch located in an inner aft compartment of the aforesaid hull, the hatch having a body with opposing flanks or sides pivoted on the hull, and upper and lower edges. The hatch includes pivot members associated with the flanks or sides in the proximity of the upper edge and in the proximity of the lower edge, the pivot members being movable towards the inside and towards the outside of these flanks so they can protrude from the flanks in combination or alternatively to each other, thereby allowing the hatch to assume, alternatively, a position in which it is closed on to the compartment, a first position of opening to an upper part of the hull, or a second position of opening to a lower part of the hull.
