Abstract
Abstract A cover for a hatch includes a rigid main body member and a sealing member secured to the main body member. The sealing member is an expanded polyethylene foam; and it extends across the hatch and engages the portion of the structural member or deck adjacent the hatch. The sealing member, thus, seals the hatch and insulates the compartment below the hatch. It acts as a gasket seal for the cover, and provides sound dampening, corrosion protection, and other advantages.
