Abstract
Abstract A floating debris recovery basket is disclosed which is particularly useful in combination with a highly maneuverable catamaran type vessel. The basket is removably secured to the vessel and located between the twin hulls thereof. When the container-like basket is filled with debris, the vessel backs away from the basket leaving it floating for subsequent removal. Floatation of the basket is preferably accomplished by filling hollow side walls thereof with buoyant material.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
115 words
In combination an independently floatable debris recovery basket having a predetermined width; a catamaran type vessel having a deck and a pair of hulls spaced apart by a distance greater than said predetermined width; said vessel having propulsion means thereon whereby said vessel can be moved relative to said basket such that said basket can occupy a free position outside the confines of said hulls and a nestled position within the confines of said hulls; stop means provided on said vessel for stopping the relative movement between said vessel and said basket to establish said nestled position; and fastening means for removably securing said basket to said vessel when said basket occupies said nestled position.
Claim 2
Dependent Claim
115 words
In combination an independently floatable debris recovery basket having a predetermined width; a catamaran type vessel having a deck and a pair of hulls spaced apart by a distance greater than said predetermined width; said vessel having propulsion means thereon whereby said vessel can be moved relative to said basket such that said basket can occupy a free position outside the confines of said hulls and a nestled position within the confines of said hulls; stop means provided on said vessel for stopping the relative movement between said vessel and said basket to establish said nestled position; and fastening means for removably securing said basket to said vessel when said basket occupies said nestled position.
Claim 3
Dependent Claim
43 words
The combination of claim 1 wherein said basket comprises a bottom; a pair of side walls upstanding from said bottom along opposite sides thereof; a rear wall; front wall means; and floatation means cooperatively associated with said side walls for floating said basket.
Claim 4
Dependent Claim
25 words
The debris recovery basket of claim 2 wherein said side walls including pockets therein; and said floatation means incluDes buoyant material located in said pockets.
Claim 5
Dependent Claim
14 words
The debris recovery basket of claim 3 wherein said buoyant material comprises polyurethane foam.
Claim 6
Dependent Claim
25 words
The debris recovery basket of claim 2 wherein said bottom, said rear wall, and said front wall means include major surface area porous to fluid.
Claim 7
Dependent Claim
23 words
The debris recovery basket of claim 5 wherein said major surface areas comprise screening having intersticial spaces permitting the passage of fluid therethrough.
Claim 8
Dependent Claim
25 words
The debris recovery basket of claim 5 wherein said front wall means is movable between open and closed positions with respect to said side walls.
Claim 9
Dependent Claim
44 words
The debris recovery basket of claim 5 wherein said front wall means comprises first and second gates swingly secured to respective ones of said pair of side walls and movable between open and closed positions with respect to one another and said side walls.
Claim 10
Dependent Claim
38 words
The combination of claim 2 whereIn said hulls have a predetermined height and wherein said side walls are of a height less than said predetermined height and are spaced apart by a distance less than said predetermined width.
Claim 11
Dependent Claim
65 words
The combination of claim 1 wherein said deck comprises a screen-like structure having a plurality of intersticial openings therethrough; and said fastening means includes elongated fastening elements removably securable at one end thereof to predetermined locations on said basket; said fastening elements being selectively inserted through those of said instersticial openings which are most closely situated with respect to said predetermined locations on said basket.
Claim 12
Dependent Claim
27 words
The combination of claim 1 and further including a pair of bow wings movably secured to said pair of hulls respectively for guiding debris into said basket.
Claim 13
Dependent Claim
100 words
For use with a catamaran type vessel having: a deck and a pair of hulls spaced apart by a predetermined distance, propulsion means for driving said vessel, and stop means positioned between said hulls to establish a nestled position for a floatable debris recovery basket slid between said hulls; the improvement comprising an independently floatable debris recovery basket slidable relative to said hulls between a free position outside the confines of said hulls and a nestled position established by said stop means; and fastening means for removably securing said basket to said vessel when said basket occupies said nestled position.
Claim 14
Dependent Claim
100 words
For use with a catamaran type vessel having: a deck and a pair of hulls spaced apart by a predetermined distance, propulsion means for driving said vessel, and stop means positioned between said hulls to establish a nestled position for a floatable debris recovery basket slid between said hulls; the improvement comprising an independently floatable debris recovery basket slidable relative to said hulls between a free position outside the confines of said hulls and a nestled position established by said stop means; and fastening means for removably securing said basket to said vessel when said basket occupies said nestled position.
