Abstract
Abstract This invention relates to marine skimmer craft that is, watercraft of the kind that is only partially immersed and skims along the surface of the water under propulsion, the craft being supported at least partly by aerodynamic force produced by suitable support structure. According to this invention the support structure comprise wings located in at least two planes: each wing consists of at least two wing panels joinable by their mutually adjacent lateral edges whereby the number of wing panels actually used may be selected in dependence upon the desired lift characteristics and the desired position of the center of gravity of the craft as a whole. As an example, two wing panels may be arranged in one plane on either side of the craft and four wing panels in another plane above its stern.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
218 words
A marine skimmer craft comprising an elongated body with anterior and posterior opposite ends thereof; a propulsion means for driving the body, mounted on said posterior end; at least two sets of wings mounted on the elongated body, each set having a wing extending laterally opposite from a remaining wing of the set extending in an opposite direction from an opposite side of the body, the wings of each set having upper and lower substantially flat surfaces positioned in substantially horizontal planes relative to the elongated body in a substantially horizontal plane, one set being mounted on the elongated body at an upper portion of the posterior end, a remaining other set being mounted substantially intermediately between said anterior and posterior opposite ends, in a different lower plane relative to said upper portion; and forward pivotable control-surface elements, one element mounted on each of opposite sides of the elongated body at said anterior end, each extending laterally in opposite directions from one-another each in a substantially horizontal plane laterally; and each wing comprising a plurality of panels elongated from front to back with each of lateral edges extending between the front and the back and being adapted for mating with a lateral edge of another panel, at least two panels for each wing being in a mated state.
Claim 2
Dependent Claim
218 words
A marine skimmer craft comprising an elongated body with anterior and posterior opposite ends thereof; a propulsion means for driving the body, mounted on said posterior end; at least two sets of wings mounted on the elongated body, each set having a wing extending laterally opposite from a remaining wing of the set extending in an opposite direction from an opposite side of the body, the wings of each set having upper and lower substantially flat surfaces positioned in substantially horizontal planes relative to the elongated body in a substantially horizontal plane, one set being mounted on the elongated body at an upper portion of the posterior end, a remaining other set being mounted substantially intermediately between said anterior and posterior opposite ends, in a different lower plane relative to said upper portion; and forward pivotable control-surface elements, one element mounted on each of opposite sides of the elongated body at said anterior end, each extending laterally in opposite directions from one-another each in a substantially horizontal plane laterally; and each wing comprising a plurality of panels elongated from front to back with each of lateral edges extending between the front and the back and being adapted for mating with a lateral edge of another panel, at least two panels for each wing being in a mated state.
Claim 3
Dependent Claim
46 words
A marine skimmer craft of claim 1, including at least three retractable wheel means for providing wheels for rolling on when on land and for retracting when skimming on water surface, mounted in positions to provide support for the elongated body to which they are attached.
Claim 4
Dependent Claim
19 words
A marine skimmer craft of claim 2, in which said propulsion means comprises a partially enclosed air-screw propulsion unit.
Claim 5
Dependent Claim
58 words
A marine skimmer craft of claim 3, in which one of said wheel means is about centrally located in juxtaposition to said interior end and in which a remaining two of said wheel means are laterally spaced from one-another located in juxtaposition to said posterior end, and including an upright pivotably mounted control element below said anterior end.
