Bow visor

From Wikipedia, the free encyclopedia

A bow visor is a feature of some ships, particularly ferries and ROROs, that allows the bow to articulate up and down, giving access to a cargo ramp and storage deck near the water line.

There have been several incidents where bow visors have partially opened while in motion, and as a result, some ships have had to have their visor locking mechanisms strengthened. Bow visor failure has also directly caused some ships to sink, most notably the M/S Estonia.
