Abstract
A marine hatch assembly includes a rectangular ring shaped frame, a hatch cover hinged to the frame and a pivotal adjustment mechanism or adjuster for maintaining the hatch in a predetermined open position. The adjusting mechanism or adjuster includes a pair of telescoping elements one of which has a flexible joint therein. This flexible joint is prevented from flexing by the other of the telescoping elements until that element is withdrawn to a point beyond the flexible joint i.e., when the hatch cover is rotated beyond a predetermined angle. The adjusting mechanism also includes a clamp for maintaining the telescoping elements in a fixed relationship with respect to one another in order to maintain the hatch in a predetermined open position.
