The method comprises providing material to an extruder of an additive manufacturing apparatus, heating the material to form a flowable material; depositing the flowable material with the additive manufacturing apparatus to form an interior portion having a shape corresponding to a portion of a hull of a marine article; and depositing the flowable material with the additive manufacturing apparatus to form a support portion (82) including a curved support surface (87). The support portion (82) and the interior portion are portions of a boat mold (80), the boat mold (80) including a plurality of mold sections (90) each provided with a respective support portion (82), each support portion (82), including the curved support surface (87), formed integrally with the corresponding mold section (90).

The invention, called "GI.CA. System", refers to a process of design and construction of artefacts in which is required high structural strength combined with lightness and small size of the structure itself. The main targets of this way of construction are therefore all the hulls of boats and in general the fuselages of the means of transport. The structural development of the artefact is realized through the use of tubes (1) adjacent to one another and arranged longitudinally. Such organized structure is then linked externally and internally by a special biaxial fabric (2). The effects of the invention are: a greater structural strength and a reduced weight, thus saving on costs of propulsion; a greater safety, especially in the marine sector: the air in the tubes is in fact a good reserve of buoyancy; a greater freedom in managing the interior space.

The invention relates to a method and to a device for producing a boat-type body (10) of a water sport device. According to the invention, a rotating frame (12), which is pre-formed about an access opening of the boat-like body (10), is arranged on an inner side of a negative mould. The outer shape of the boat-type body (10) is predetermined, essentially, by the innerside of the negative mould. The boat-like body (10) is produced in the inner side of the mould by means of a thermoplastic shaping method. During the shaping process, at least one part of the surface of the rotating frame (12) is in contact with the boat-like body (10) which is formed by the thermoplastic shaping method. The invention also relates to a water sport device.
