Nautical Term: Plimsoll mark
Definition of Plimsoll mark
The Plimsoll mark is a critical loadline indicator on a ship. This mark is depicted as a circle intersected by a horizontal line. In addition, accompanying letters identify the authoritative body responsible for assigning the ship’s loadline.
For instance, during the process of loading cargo on a ship, the master must ensure that the ship’s load does not exceed its assigned Plimsoll loadline. This mark, which is easily visible on the ship’s side, serves as an essential safety measure that helps prevent the ship from becoming overloaded, thereby minimizing the risks of capsizing or sustaining significant damage during rough sea conditions.
