The Keep closed at sea sign is a laminated information sign for onboard use, which makes it easy to indicate that a hatch, door, or installation must be kept closed while sailing.
The laminated finish provides a more robust surface for daily use, and the sign is suitable for interiors where clear signage increases safety and order on board.
