Gliding boat

Claim 2

A gliding boat comprising a central hull pivotally suspended between two self-stabilizing lateral floats so as to be always in a vertical position, independently of the raising or lowering of the lateral floats, by a supporting structure connected by means of supporting beams to the lateral floats arranged in parallel and sYmmetrically relative to the hull at a distance from each other which is a function of the angle defined between the hull and the supporting structure and is smallest when such angle has an aperture of 90*, which is the case when the gliding boat floats on clam sea.

Claim 3

A gliding boat as claimed in claim 1, wherein four rigid beams are secured to each float and are connected upwardly in pairs so as to form four inverted U''s facing one another and connected to two lateral transverse beams pivotally supporting the hull through a longitudinal supporting shaft extending longitudinally of the hull and pivotally mounted upwardly thereof in said lateral transverse beams, said shaft being secured to the hull in at least two points and carrying at each end a crank connected through an articulated rod system to the beams secured to the floats so that any deviation of the floats from their vertical position will increase the distance between the floats and will increase the supporting basis of the boat on the water surface.

Claim 4

A gliding boat as claimed in claim 1, wherein the articulated rod system is capable of coping with an extreme tilting movement and for this purpose comprises two first cranks at the end of said longitudinal supporting shaft, the two cranks being in asymmetrical relation to each other and the driving end of each crank carries a second crank forming a double-armed crank with each of said first cranks at the ends of said longitudinal supporting shaft so that the two driving ends of the first cranks are disposed symmetrically on the same horizontal line relative to the longitudinal supporting shaft and a first connecting rod is pivotally connected with one of its ends to a connecting pin between each of the double-armed cranks and with the other end to first supporting beams located outwardly of the double-armed cranks and a second connecting rod is pivotally connected with one of its ends to one arm of each of the double-armed cranks outwardly of this crank and with the other end to second supporting beams located outwardly of the double-armed cranks, opposite said first supporting beams, so that in the case of extreme tilting of the boat the first connecting rod can move between the double-armed crank without interfering with the second connecting rod, the supporting beams of each connecting rod being rigidly secured to and projecting from said rigid beams secured to the floats.

Claim 5

A gliding boat as claimed in claim 1, wherein the central hull is rearwardly provided with a gangway extensible by winches and a driving and steering unit accommodated in a tubular housing and comprising a drive screw located between two baffle plates serving as rudders, said tubular housing being connected to the central hull through an elongated supporting arm and extending in the longitudinal direction of the central hull and in the direction of intended movement of the boat so as to be capable of directing the flow of water therethrough in cooperation with said baffle plates.

Claim 6

A gliding boat as claimed in claim 3, wherein the elongated supporting arm of said tubular housing for the driving and steering unit is extensible and retractable.

Claim 7

A gliding boat as claimed in claim 3, wherein the elongated supporting arm of said tubular housing for the driving and steering unit is foldable.
