A hatch (12, Fig 1) configured to be fitted into a deck (14, Fig 1) of a marine craft (10, Fig 1). The hatch comprises a four-sided frame 24 configured to be attached in an opening in the deck and a four-sided lens 20 moveable between a closed configuration in which the lens seals against the frame and an open configuration in which the lens is disposed in a position tilted upwardly away from the frame. First and second hinge arrangements (50, 52, Fig 5) are disposed on opposing sides of the frame. When the hatch is opened from the closed configuration, the movement of the lens relative to the frame is constrained by the first and second hinge arrangements so that both a major opening side 20a of the lens and a minor opening side 20b of the lens move upwards and away from the frame for at least part of the range of movement of the lens relative to the frame.
