Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
37 words
Unsinkable craft able to be steered even on the crest of very high waves by paddlers who are neither sitting nor standing, but kneeling'with both legs, folded so as to realize a new and functional operating position.
Claim 2
Dependent Claim
37 words
Unsinkable craft able to be steered even on the crest of very high waves by paddlers who are neither sitting nor standing, but kneeling'with both legs, folded so as to realize a new and functional operating position.
Claim 3
Dependent Claim
102 words
Craft as claimed in claim 1 realized in plastic or other materials, with a hull completely empty or filled with porous light substances (such as expanded polystyrene and the like) with a tapered shape at the ends for hydrodynamics; equipped corresponding to the central part with a place for the knees of one or more paddlers, realized with two impressions parallel to the axis of symmetry and separated by a median swelling to allow the paddlers to mount it; some holes between said impressions and the external edge above the water line allow any water which enters the space to flow out.
Claim 4
Dependent Claim
94 words
Craft as claimed in the preceding claims, wherein hull 1 is completely closed with no internal access, and on its upper surface are realized, with no loss of continuity, the two impressions 2 and 2', parallel to the axis of symmetry 3 and to central swelling 4, with holes 5 for water outlet; the tapered bow 6 and stern 7 (also tapered but at a slightly milder curvature) and eventual keel 8 allow the craft to be powered and steered with paddles on the crest of the waves, thus realizing exceptional entertainment and functionality.
Claim 5
