    Patent number: 4375199
    Abstract: A submersible or semi-submersible structure, such as a boat, oil rig or pipeline, has an anti-fouling covering secured thereto. The covering comprises a mesh of copper or copper alloy embedded in a carrier, preferably of plastics material. The mesh has knuckles which on one surface are close to or protrude from the carrier so as to be accessible to sea water. The knuckles are spaced from the other surface so as to prevent contact between the structure and the mesh. A sea water permeable coating may be provided on the outer surface.
