Bulwark – Definition and Pronunciation
What is Bulwark?
Bulwark is an upward extension of the hull that forms a low wall around the edge of the deck. Keeps the decks drier in moderate conditions and provides additional security for the crew.
Examples of Bulwark
A solid hardwood bar (one to three feet long) inserted along the inside of a ship’s bulwarks to secure lines. Because of its bulbous top portion and cylindrical shaft, a belaying pin makes a formidable club/impact weapon.
From “Review of Pirate Tactics in Ship Combat”.
When the inboard end of the gangway or accommodation ladder rests on or is flush with the top of the bulwark, a bulwark ladder should provided. Any gap between the bulwark ladder and the gangway or accommodation ladder should be adequately fenced to a height of at least metre.

I had cut away one of the straps and part of the lacing when I saw the water pouring over the bulwark under the Captain’s Bridge. I realised that the ship was pitching forward, so ran to the end of the deck, got over the side and slipped down to the «B» deck, then to the «C» deck; as I steadied myself the water ran over my boots and when it had got to my knees I sprang away and swam as hard as I could.
