Hump ​​deck

A humpback deck , also called a waldeck (after the humpback of a whale), was a common way of shaping the back deck of a passenger ship between 1885 and 1900 . It did not join the ship's side with a sharp edge , but with a round transition. The strong curvature of the deck served to allow the water from high waves to drain off as quickly as possible.

When the number of decks exceeded three, and the waves consequently no longer hit the deck to the same extent as before, the whale or humpback deck also disappeared and the area on the forecastle deck for the passengers became larger.
