Abstract
Abstract A floating breakwater has two closed buoyant cylindrical members spaced laterally from each other and joined together in their spaced positions by longitudinally spaced flexible and inextensible strips such as rubberized fabric. Closed elongated tubular members are mounted on the cylindrical members where they will be above water. The breakwater is anchored to the bottom of the waterway by chains or the like and conventional anchors.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
95 words
A floating breakwater for protecting an area of a body of water from waves comprising at least a pair of cylindrical drum-like members, longitudinally spaced flexible and substantially inextensible strips connected at one end to one of said drum-like members and connected to another of said drum-like members at the other end, closed hollow tubular members of smaller cross section than the cylindrical members fixed to said cylindrical members above the water level and means for anchoring the first and last of said cylindrical members while afloat to the bottom of a body of water.
Claim 2
Dependent Claim
95 words
A floating breakwater for protecting an area of a body of water from waves comprising at least a pair of cylindrical drum-like members, longitudinally spaced flexible and substantially inextensible strips connected at one end to one of said drum-like members and connected to another of said drum-like members at the other end, closed hollow tubular members of smaller cross section than the cylindrical members fixed to said cylindrical members above the water level and means for anchoring the first and last of said cylindrical members while afloat to the bottom of a body of water.
Claim 3
Dependent Claim
83 words
A floating breakwater comprising at least two elongated closed bodies disposed with their greater dimension substantially perpendicular to the predominant direction of incoming waves and disposed in parallel spaced relationship, means anchoring the first and last of said elongated closed bodies and flexible strips connecting adjacent elongated closed bodies to impart to them a to and fro motion whereby the upper part of the portion of water between adjacent elongated closed bodies assumes vertical and turbulent motions interacting and abating the incoming waves.
Claim 4
Dependent Claim
83 words
A floating breakwater comprising at least two elongated closed bodies disposed with their greater dimension substantially perpendicular to the predominant direction of incoming waves and disposed in parallel spaced relationship, means anchoring the first and last of said elongated closed bodies and flexible strips connecting adjacent elongated closed bodies to impart to them a to and fro motion whereby the upper part of the portion of water between adjacent elongated closed bodies assumes vertical and turbulent motions interacting and abating the incoming waves.
Claim 5
Dependent Claim
25 words
The floating breakwater of claim 2 comprising means for exercising a return pull to increase the to and fro motion of said elongated closed bodies.
Claim 6
Dependent Claim
12 words
The floating breakwater of claim 2 wherein the flexible strips are inextensible.
Claim 7
Dependent Claim
31 words
The floating breakwater of claim 2 wherein the flexible strips connecting the said elongated closed bodies to each other cover substantially the entire water surface and are of inextensible sheet material.
