Abstract
A hatch for a boat or other vehicle having a cover (10) that is pivotally connected to a frame (12) by a pair of releasable hing assemblies (32) that allow separation of the cover from the frame when the cover is forcibly opened against an object on an adjacent surface (14). A pair of pivotal handles (60) are restrained against movement into a downward angular position that would interfere with the proper closure of the cover.
