Abstract
Abstract This invention relates to a shore protection device and more particularly to breakwaters for protecting shorelines against wave damage and erosion. The floating breakwater is manufactured primarily from steel plate between 154" thick and 3/16" thick which may be cold rolled steel. The assembly is basically similar to a large floating barge that has some unique design characteristics that allow it to have excellent performance as a breakwall. It is designed to be simple and easy to manufacture, (there are no unusual bending or rolling operations required) and it may be floated to the site or the shoreline which needs protection. Its main feature is that it is designed to break up the tremendous power and force of wave action as the waves come rolling toward the shore, which makes the wave quiescent as it continues on toward the shoreline after it goes over and under the floating breakwater. The wave is quieted to the extent that the wave will deposit sand and suspended solids and thereby continue to protect and build the shoreline.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
249 words
A floating breakwater comprising an elongated hollow body having a top, bottom, first side, second side, first end and a second end attached together forming a water tight body, a plate-like keel fixed to said bottom of said body and extending downwardly and extending from one end of said body to the other, first outrigger means attached to said first side and extending outwardly therefrom, second outrigger means attached to said second side of said body and extending outwardly therefrom, first swivel means is pivotally attached to said first end of said breakwater, second swivel means pivotally attached to said second end of said breakwater, said swivel means having means thereon to attach said swivel means to an anchor line whereby said breakwater can be anchored in place along a shoreline for decelerating waves, said hollow body having bulkheads therein attached to said first side of said body, to said second side of said body, to said bottom of said body dividing said body into a plurality of compartments, whereby a water ballast in said breakwater is prevented from flowing from one end thereof to the other to change the weight thereof, said bulkheads having laterally spaced openings through them allowing water in said breakwater to redistribute itself in said body at a controlled rate to restrain the movement of said breakwater, said top of said body has spaced openings therein and covers for said spaced openings whereby ballasts can be introduced into and removed from said breakwater body.
Claim 2
Dependent Claim
249 words
A floating breakwater comprising an elongated hollow body having a top, bottom, first side, second side, first end and a second end attached together forming a water tight body, a plate-like keel fixed to said bottom of said body and extending downwardly and extending from one end of said body to the other, first outrigger means attached to said first side and extending outwardly therefrom, second outrigger means attached to said second side of said body and extending outwardly therefrom, first swivel means is pivotally attached to said first end of said breakwater, second swivel means pivotally attached to said second end of said breakwater, said swivel means having means thereon to attach said swivel means to an anchor line whereby said breakwater can be anchored in place along a shoreline for decelerating waves, said hollow body having bulkheads therein attached to said first side of said body, to said second side of said body, to said bottom of said body dividing said body into a plurality of compartments, whereby a water ballast in said breakwater is prevented from flowing from one end thereof to the other to change the weight thereof, said bulkheads having laterally spaced openings through them allowing water in said breakwater to redistribute itself in said body at a controlled rate to restrain the movement of said breakwater, said top of said body has spaced openings therein and covers for said spaced openings whereby ballasts can be introduced into and removed from said breakwater body.
Claim 3
Dependent Claim
20 words
The breakwater recited in claim 1 wherein said top of said body is flat, said spaced openings therein have covers.
Claim 4
Dependent Claim
22 words
The breakwater recited in claim 1 wherein said top is flat and said bottom is flat and generally parallel to said top.
Claim 5
Dependent Claim
36 words
The breakwater recited in claim 3 wherein said keel has a plate-like configuration and is fixed to said bottom, spaced gussets are fixed to said bottom and to said keel for holding said keel is position.
Claim 6
Dependent Claim
32 words
The breakwater recited in claim 4 wherein spaced relatively large holes are formed in said keel and disposed between said gussets whereby water can flow through said holes having its velocity reduced.
Claim 7
Dependent Claim
155 words
A floating breakwater comprising an elongated hollow body having a top, bottom, first side, second side, first end and a second end attached together in water tight relation, a plate-like keel fixed to said bottom of said body and extending downwardly and extending from one end of said body to the other, first outrigger means attached to said first side and extending outwardly therefrom, second outrigger means attached to said second side of said body and extending outwardly therefrom, first swivel means pivotally attached to said first end of said breakwater, second swivel means pivotally attached to said second end of said breakwater, said swivel means having means thereon to attach said swivel means to an anchor line whereby said breakwater can be anchored in place along a shoreline for decelerating waves, said body has spaced bulkheads on the inside thereof, each said bulkhead engages said top, bottom, sides and form partitions in said body.
Claim 8
Dependent Claim
155 words
A floating breakwater comprising an elongated hollow body having a top, bottom, first side, second side, first end and a second end attached together in water tight relation, a plate-like keel fixed to said bottom of said body and extending downwardly and extending from one end of said body to the other, first outrigger means attached to said first side and extending outwardly therefrom, second outrigger means attached to said second side of said body and extending outwardly therefrom, first swivel means pivotally attached to said first end of said breakwater, second swivel means pivotally attached to said second end of said breakwater, said swivel means having means thereon to attach said swivel means to an anchor line whereby said breakwater can be anchored in place along a shoreline for decelerating waves, said body has spaced bulkheads on the inside thereof, each said bulkhead engages said top, bottom, sides and form partitions in said body.
Claim 9
Dependent Claim
24 words
The breakwater recited in claim 6 wherein said bulkheads have holes therein provided for circulating water in said body to distribute as ballast therein.
Claim 10
Dependent Claim
28 words
The breakwater recited in claim 7 wherein a plurality of said breakwaters are provided, means is provided for flexibly connecting said breakwaters together forming a line of breakwaters.
Claim 11
Dependent Claim
41 words
The breakwater recited in claim 7 wherein said outriggers each have an outer end, a rail is attached to said outer end of each said outrigger and extends from one end of said breakwater to the other for stabilizing said breakwater.

Claim 13
Dependent Claim
43 words
The floating breakwater recited in claim 10 wherein said first swivel means and said second swivel means have means thereon to attach said swivel means to an anchor line whereby said breakwater can be anchored in place along a shoreline for decelerating waves.
