A sea chest cover for providing access to the sea chest of a ship. The sea chest cover includes both a cover element and a liner element received within the interior of the sea chest and is fabricated essentially entirely of one or more viscoelastic materials, preferably either polyethylene or polyurethane. Materials can be also made of copolymers, which may be laminated, and compression molded or portions may be blow molded. Fabrication of the sea chest cover from a viscoelastic material reduces or eliminates corrosion and erosion problems. It also minimizes marine organism and ice build-up. The result is a reduction in the expense of associated with maintaining such covers. The sea chest cover can also include an additive to reduce bacteria and algae growth and be irradiated with gamma rays for increased strength.
