Abstract: Boarding systems for retractable ladder boats comprising a stern platform and a retractable ladder; a water-tight casing-sheath for said ladder, equipped, inside, with sliding guides and incorporated in the stern platform, comprises a plurality of sliding slides, housed and limited inside the casing-sheath. The stern platform favors a receiving space, provided inside or outside, for receiving the casing-sheath and its optimal fixing. The sliding slides have a free stroke on the entire length of the sliding guides since such free stroke is limited at the ends of the sliding guides opening out on the opening port, through locking elements that allow the sliding slides to partially slip out from the sliding guides. The casing-sheath is retractably housed inside the housing space, formed in the stern platform.

Abstract: A connection device of a loop of a mooring line for a recreational craft and the like to a fastening element associated with a mooring quay is described, of the type comprising at least one pair of opposite ends intended to be joined together and firmly attached to the loop of the mooring line. Advantageously, such a connection device comprises a flexible core having a flat cross section and fitted into a cover sheath, with which it substantially constitutes a single body, the cover sheath extending along the flexible core so as to expose the substantially loop-shaped opposite ends.

Abstract: The present invention relates to a protection and finish structure of the border of a boat hull with simplified assembly, of the type comprising a profile being extended in a longitudinal direction and a plurality of fixing means for fixing the profile to the hull, distributed along said profile. The fixing means of the structure comprise at least a fast clutch with a tenon and mortise joint wherein a tenon element, fixed to the profile, and a mortise element, intended for being fixed to the hull, have respective tenons and mortise being mutually engaged in a longitudinally sliding way.

Abstract: A press for splicing the ends of cables, ropes and the like is described. The press is of the type which utilizes an hydraulic cylinder (5) positioned vertically and resting on a base (6). An upper frame (8) comprises a plate (9) which is fixed to the hydraulic cylinder. The piston of the cylinder has a stem which protrudes from the plate. The frame additionally comprises two lateral plates (10) opposite one to the other and arranged in the shape of a "U" and an upper plate (11) which provides support pressure. Each of the lateral plates has an opening and a loader is inserted within the openings. The loader consists of two half-matrixes, which have a plurality of notches of different diameters whereby when the half-matrixes are approached one to the other a plurality of shaped openings of different diameters is formed.

Abstract: The device comprises a base (1) having an opening and a tapered orifice (7) in the interior. A conical body (8) is housed within the tapered orifice, the conical body (8) consisting of two elements (10) which form a central threaded opening (9). The elements (10) resist longitudinal displacement but are capable of radial displacement. The elements (10) are identical and each one of them is provided with a recess and a projection so that they can engage with each other.The device also comprises a spring and a closure head (14).
