Abstract

Abstract A hull for a watercraft, and in particular for a sport boat, adapted to ally both stability and instability without sacrificing or opposing one to the other; this being achieved by forming a transverse bottom outline which combines typical rounded and substantially planar bottom portions transversely adjacent each other, with the planar outline portions extending on opposite sides of the rounded portion lengthwise of the hull, elevated relative to the rounded portion and forming inflections therewith and longitudinally thereof. The planar outline portions are arranged to provide dynamic sustentation upon impact thereon of waves produced by the suitably shaped bow portion. The hull further includes a top deck forming section defining longitudinally reinforcing wall portions, footrest depressions on opposite sides of a central longitudinal seat supporting boss, and a trench-like depression extending lengthwise of the hull to recess the control links therein.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 342 words
In a watercraft, a hull comprising a bottom section including a bow portion of forwardly tapering shape having a transverse cross-sectional bottom outline of generally V-shape and a main hull portion merging with said bow portion and having a central longitudinal portion of convex rounded transverse cross-sectional bottom outline, and lateral longitudinal stabilizing portions flanking said central longitudinal portion and extending laterally away therefrom on opposite sides thereof respectively, each of said stabilizing portions having a bottom surface which is flat and straight transversely and longitudinally of the hull, said bottom surface being substantially parallel to the bottom surface of the main hull portion throughout the length of the latter, each bottom surface of said stabilizing portions being upwardly inclined transversely of the hull and defining a longitudinally extending inflection with said central longitudinal portion, said bottom surfaces of said stabilizing portions lying above the waterline of the hull, and further including a deck forming section co-extensive with said bottom section peripherally sealed to the latter and forming a fully enclosed fluid-tight buoyant enclosure therewith, said deck forming section forming a central boss extending longitudinally of the hull, a pair of foot-rest depressions extending lengthwise of said central longitudinal boss on opposite sides thereof respectively, and lateral bumps extending lengthwise of said hull along the outer lateral sides thereof, said boss having a trenchlike longitudinal depression extending lengthwise thereof to the stern of the hull and adapted for recessing watercraft controls therein exterior of said fluid-tight buoyant enclosure and for exterior connection of the same with an outboard motor at the stern, said deck forming section having a recess therein forward of said longitudinal depression, in communication with the latter and arranged to recess a fuel tank therein on the exterior of said fluid-tight buoyant enclosure, said trench-like longitudinal depression and said recess opening upwardly at the top of said deck forming section in longitudinal alignment with each other, a seat mounted on top of said central boss over said depression and a cover engaging over said recess to close the latter.
Claim 2
Dependent Claim 342 words
In a watercraft, a hull comprising a bottom section including a bow portion of forwardly tapering shape having a transverse cross-sectional bottom outline of generally V-shape and a main hull portion merging with said bow portion and having a central longitudinal portion of convex rounded transverse cross-sectional bottom outline, and lateral longitudinal stabilizing portions flanking said central longitudinal portion and extending laterally away therefrom on opposite sides thereof respectively, each of said stabilizing portions having a bottom surface which is flat and straight transversely and longitudinally of the hull, said bottom surface being substantially parallel to the bottom surface of the main hull portion throughout the length of the latter, each bottom surface of said stabilizing portions being upwardly inclined transversely of the hull and defining a longitudinally extending inflection with said central longitudinal portion, said bottom surfaces of said stabilizing portions lying above the waterline of the hull, and further including a deck forming section co-extensive with said bottom section peripherally sealed to the latter and forming a fully enclosed fluid-tight buoyant enclosure therewith, said deck forming section forming a central boss extending longitudinally of the hull, a pair of foot-rest depressions extending lengthwise of said central longitudinal boss on opposite sides thereof respectively, and lateral bumps extending lengthwise of said hull along the outer lateral sides thereof, said boss having a trenchlike longitudinal depression extending lengthwise thereof to the stern of the hull and adapted for recessing watercraft controls therein exterior of said fluid-tight buoyant enclosure and for exterior connection of the same with an outboard motor at the stern, said deck forming section having a recess therein forward of said longitudinal depression, in communication with the latter and arranged to recess a fuel tank therein on the exterior of said fluid-tight buoyant enclosure, said trench-like longitudinal depression and said recess opening upwardly at the top of said deck forming section in longitudinal alignment with each other, a seat mounted on top of said central boss over said depression and a cover engaging over said recess to close the latter.
Claim 3
Dependent Claim 138 words
In a watercraft, a hull comprising a bottom section including a bow portion and a main hull portion merging aftward with said bow portion, a deck forming section co-extensive with said bottom section, peripherally sealed to the latter and forming a fully enclosed fluid-tight buoyant enclosure therewith, each of said deck forming section and said bottom section being formed into a single piece and said sections having complementary peripheral edges engaging in sealed abutment against each other, said deck forming section having an upwardly projecting central boss extending longitudinally of said hull and the Latter having a trench-like longitudinal depression extending lengthwise thereof to the stern of the hull and adapted for recessing watercraft controls therein on the exterior of said fluid-tight buoyant enclosure and for exterior connection of the same to an outboard motor at the stern.
Claim 4
Dependent Claim 138 words
In a watercraft, a hull comprising a bottom section including a bow portion and a main hull portion merging aftward with said bow portion, a deck forming section co-extensive with said bottom section, peripherally sealed to the latter and forming a fully enclosed fluid-tight buoyant enclosure therewith, each of said deck forming section and said bottom section being formed into a single piece and said sections having complementary peripheral edges engaging in sealed abutment against each other, said deck forming section having an upwardly projecting central boss extending longitudinally of said hull and the Latter having a trench-like longitudinal depression extending lengthwise thereof to the stern of the hull and adapted for recessing watercraft controls therein on the exterior of said fluid-tight buoyant enclosure and for exterior connection of the same to an outboard motor at the stern.
Claim 5
Dependent Claim 41 words
A watercraft as defined in claim 2, wherein said deck forming section has a recess therein forward of said depression, in communication with the latter and arranged to recess a fuel tank therein on the exterior of said fluid-tight buoyant enclosure.
Claim 6
Dependent Claim 49 words
A watercraft as defined in claim 3, wherein said trench-like longitudinal depression and said recess open upwardly at the top of said deck forming section, a seat is mounted on top of said central boss over said depression and a cover engages over said recess to close the latter.
