A watercraft includes a plurality of separable body sections (2101, 2102, 2103, 2104, 2105, 2106) configured for assembly into a single assembled structure (2100) having a first length, and for packing into a packed structure (3000) having a second length smaller than the first length. The single assembled structure may be held together using latching devices, one or more of the latching devices including a latch unit comprising a latch support, a spring mount and a band spring, the band spring having a first spring end and a second spring end, wherein the latch support includes a latch and a first shaft positioned in relationship to the latch, the first shaft configured for rotatably mounting the first spring end of the band spring, and the spring mount includes a second shaft configured for rotatably mounting the second spring end of the band spring.

The invention relates to an inflatable watercraft which consists of at least two inflatable parts that are joined together by means of holding strips or the like under preload. The invention also relates to a method for producing said inflatable watercraft and a gluing table that can be used in the production of the watercraft.

A collapsible water vessel has a center hull section, a first plurality of hull extensions longitudinally slidable through an opening at a first end of the center hull section between extended and collapsed positions, and a second plurality of hull extensions longitudinally slidable through an opening at a second end of the center hull section between extended and collapsed positions. When the first plurality of hull extensions are in the extended configuration, adjacent hull extensions thereof form a sealing contact therebetween and an inboard most hull extension thereof forms a sealing contact with the center hull section. And when the second plurality of hull extensions are in the extended configuration, adjacent hull extensions thereof form a sealing contact therebetween and an inboard most hull extension thereof forms a sealing contact with the center hull section.

A transparent modulatable kayak with shading system includes two pairs of fitting devices, reversibly connecting multiple kayaks. The tubular body of the paddle is reversibly divisible at the center. The inner volume of the hull has a container housing a cloth adapted to shade the user on the seat. The upper surface of the hull has a plurality of recesses, of which at least one pair is positioned at the bow and at least one pair is positioned at the stern, each housing a portion of the tubular body of the paddle. The tubular body includes, at each end, at least one coupling device adapted to reversibly connect at least one of the corresponding coupling devices of the cloth. The hull is made of any natural or synthetic polymer adapted to ensure the floating of the kayak and its total transparency.

A collapsible folding boat that includes two or more hulls. The individual hulls can either be directly connected together or connected using one or more structural members. In addition, the multiple hull folding boat can make use of inflatable air chambers and/or rigid components as part of its final assembly. The multiple hulls of the multiple hull folding boat can also be separated for use as individual collapsible boats. The multiple hull folding boat can include one or more seats for use by persons in the boat, and these seats can be placed in a lateral or longitudinal arrangement. The multiple hull folding boat also includes a removable floor design to present a dry floor to the inside of the boat.

An additional chamber to watercraft that adds both volume and curvature to other compartments or components of the watercraft that are essentially flat is described. The additional chamber provides for modular construction of watercraft for creating volumetric space as well as a curved surface to the outer portion of the watercraft. The chamber advantageously increases the aesthetic appeal of the watercraft as well as provides a surface on which water is discouraged from pooling or collecting on. Various watercrafts having such a chamber are also described.

A collapsible watercraft comprises a foldable sheet and is transitionable between a deployable kayak configuration and a stowed configuration by folding or unfolding along predefined fold lines in the foldable sheet. In the kayak configuration, the watercraft is switchable between at least a single-seat configuration and a tandem configuration by installing a desired number of seat and footrest assemblies. At least some of the seat and footrest assemblies are installed in the kayak by strapping seat and/or footrest components to loops nonreleasably attached to removable floorboards of the kayak. The removable floorboards are installed in the kayak using extruded engagement profiles.

A foldable canoe comprising includes: a gunwale formed around the hull, the hull formed of an elongate sheet of synthetic material having multiple folds including at least one longitudinal and one or more horizontal folds, with the hull configured to be folded into a stored configuration along the folds of the elongate sheet; one or more ribs installed across a width of the hull; and a gunwale cap formed of a plurality of adjoining gunwale sections, wherein each of the plurality of adjoining gunwale sections is removably secured to adjacent gunwale sections. In a deployed configuration the plurality of adjoining gunwale sections are joined such that the gunwale cap maintains a shape of the gunwale of the hull, and wherein in a stored configuration the plurality of adjoining gunwale sections are separated such that the gunwale cap is folded into a stowed configuration.
