Abstract
A plastic hatch cover is secured over a hatch opening by a hold-down bar extending across the hatch opening above the hatch cover. The hold-down bar has one end pivotally connected with a hinge bracket on the upper deck and another end engageable with a latch structure for sealing the hatch cover. The hatch cover is secured to the hold-down bar by clips on the hold-down bar adjacent the latch structure and adjacent the hinge. The clip adjacent the hinge detaches from the rest of the hold down bar when the hinge bolt is withdrawn, allowing removal of the hatch cover. Lug portions extend upwardly from the hatch cover to engage the hold-down bar to prevent lateral motion of the hatch cover with respect to the hold-down bar. The hatch cover is provided with reinforcing webs on its upper surface and on its lower surface.
