US Patent 11541965 Maritime hatch

A two-way openable maritime hatch in which the articulating components that open the hatch, and hold it in an open position, are enclosed within a waterproof seal of the hatch when in closed position. The design uses a double hinge structure, which facilitates opening the hatch in either a forward- or aft-facing position. Elastic gaskets may be used to hold the hatch open in specific positions or at specific angles. Each of the hinge systems are independently operable.
