Abstract: A hatch latch with a peripheral top surface adapted to fit through an opening in a hatch has a rotatable axial shaft with a latch member toward its lower end, the shaft being partially enclosed in an outer housing and having a central cavity at its upper end surrounded by a groove in the peripheral top surface which makes the hatch latch waterproof by draining water to the periphery by one or more channels leading to an edge of the peripheral top surface. The cavity is adapted to contain a locking device for locking a hatch that needs to be both latched and locked or a plug to fill the top of the cavity when the hatch requires only latching. A bail, D-ring or the like is used to raise and lower the shaft between secured and latched positions and, to rotate the shaft between latched and unlatched positions.
