A hatch assembly for a marine vessel included a slam latch and a frame and a cover having the slam latch disposed therein. The slam latch includes a housing having inner and outer portions and a pivotal handle for rotation between open and closed positions. A reciprocal fastening element including a second cam surface is adapted to engage the frame for retaining the cover against the frame. A spring biases the handle into a closed position and together with the first cam surface maintains the handle in an opened position when the handle is rotated through a predetermined angle. The latch also includes a push rod for converting the rotation of the handle to the reciprocal movement of the fastening element. The latch also includes a pair of seals to prevent water from passing through the latch.
