Abstract
Abstract The boat hull or hulls and necessary superstructure of small water craft are sectioned for convenience of transportation, storage, or handling, and are easily and quickly assembled and disassembled by means of pins extending from one section into another section and by removable pins which extend from one section into another section. A simple cam lock provides positive holding and quick release for the assembled parts; particularly the sectioned assembly is useful for small water craft, especially catamaran type sailboats.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
173 words
In a light-weight, small water craft arranged for quick assembly and disassembly having at least two sectioned hulls and a sectioned superstructure securable to the hulls and providing crew''s space, the improvement which comprises: a. means for securing the hull sections together including mating bores in said hulls registering at the joint between said sections and including pin means extending into said bores from one hull section to the other section and including means for releasably securing pins in said bores, b. mating bores in said superstructure and in the hull sections and pin means extending from said superstructure into the hull sections, and c. latch means for securing the superstructure to the hull sections and the hull sections together including a pair of second pin means telescoping in bores in adjacent sections of the superstructure and into bores in adjacent hull sections, said pair of second pin means having means securing the same together inclusive of quick release cinching and locking means whereby the whole assembly is secured in essentially rigid condition.
Claim 2
Dependent Claim

In a light-weight, small water craft arranged for quick assembly and disassembly having at least two sectioned hulls and a sectioned superstructure securable to the hulls and providing crew''s space, the improvement which comprises: a. means for securing the hull sections together including mating bores in said hulls registering at the joint between said sections and including pin means extending into said bores from one hull section to the other section and including means for releasably securing pins in said bores, b. mating bores in said superstructure and in the hull sections and pin means extending from said superstructure into the hull sections, and c. latch means for securing the superstructure to the hull sections and the hull sections together including a pair of second pin means telescoping in bores in adjacent sections of the superstructure and into bores in adjacent hull sections, said pair of second pin means having means securing the same together inclusive of quick release cinching and locking means whereby the whole assembly is secured in essentially rigid condition.
Claim 3
Dependent Claim
29 words
The improvement of claim 1 wherein said pin means for securing said hulls together are secured to one said hull section and telescope into the Other said hull section.
Claim 4
Dependent Claim
30 words
The improvement of claim 1 wherein said means for releasably securing said pins includes a pin passing through bores at a right angle to the longitudinal axis of said pins.
Claim 5
Dependent Claim
20 words
The improvement of claim 3 wherein said pin extends from the top of the hull section towards the bottom thereof.
Claim 6
Dependent Claim
36 words
The improvement of claim 1 wherein said second pin means extending from said superstructure are arranged in pairs, and at least one opposed pair is hollow and have means to hold the superstructure to said hulls.
Claim 7
Dependent Claim
17 words
The improvement of claim 5 wherein said quick release means conjointly holds said pairs of hollow pins.
Claim 8
Dependent Claim
26 words
The improvement of claim 1 wherein said quick release means includes an eccentrically mounted handle for cinching said section together when moved to a locked position.
Claim 9
Dependent Claim
24 words
The improvement of claim 1 wherein said quick release means are arranged to lie in a slot below the surface of said hull sections.
Claim 10
Dependent Claim
164 words
A sectioned, light-weight, catamaran boat arranged for quick assembly and disassembly comprising: a. a pair of sectioned hulls, the sections of each hull being assembled together to form two complete hulls, each hull section being completely enclosed and waterproof; b. superstructure means arranged to mate on the pair of assembled hulls to hold them in spaced parallel relation and provide crew space, said superstructure means being formed into separate sectioned portions; c. a plurality of mating bores provided between said hull sections and between said superstructure and hull sections; d. first pin means arranged to extend through the bores in said superstructure section into said hull and secure the two parts together; e. second pin means telescoping in said bores between said hull sections; f. lock means for adjacent pin means between said hull sections, and g. quick release latch means extending between said hull sections to secure the hull sections together with said superstructure by interconnecting said first pin means in said bores.
Claim 11
Dependent Claim
164 words
