ABSTRACT:
A marine door unit consists of a rigid frame adapted to be attached to a deck and a door hingably connected to the frame. The frame is a rigid metallic unit formed of channel members, at least one of which carries a drain tube to prevent water accumulation therein. The frame means includes an inner upstanding support rail which carries a continuous sealing gasket. When the door is closed, the inner surface thereof abuts against the support rail, compressing the sealing gasket and rendering the door unit substantially leak-proof. In the event of any water leakage past the edges of the door, such leakage collects in the channel and discharges through the drain tube. The door unit is particularly useful on boats of the type having a fishing platform with a storage compartment beneath the platform. On such boats, the door unit is mounted in an opening in the platform and serves to keep the compartment dry while remaining substantially flush with the platform surface.
