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: 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 favours 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: The invention relates to a protection structure for a keel or profiled parts of a boat. The protection structure has advantageously an exemplary finishing, as well as lightness and sturdiness, and comprises a section with a predetermined length and a plurality of fixing means to fix the section to the keel; the structure further comprises a recess longitudinally formed in the section and a plastic-material filling element in at least a portion of said recess.

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.
