Nautical Term: Birth marks
Definition of Birth marks
Birth marks, also known as Plimsoll marks, are distinct horizontal lines painted on the hulls of ships to indicate their loading limit. This term derives from the same name given to a significant safety regulation enacted during the mid-19th century. For example, in a paragraph discussing shipping regulations, one might write, ‘The Plimsoll Act of 1871 established regulations for the painting of Plimsoll marks on ships. These marks are used to indicate the maximum loading limit of a ship, ensuring the safety of mariners and cargo alike.’
