Question 2210 Deck General

The correct answer is A) determine the vessel's freeboard. The Plimsoll mark, also known as the load line, is a mark on the side of a ship that indicates the maximum safe draft or depth to which the vessel can be loaded. The position of the Plimsoll mark is determined by regulations and indicates the maximum allowed draft for the vessel based on the water density and weather conditions, ensuring the vessel maintains adequate freeboard (the distance between the waterline and the main deck) for safe operation. The other options (B, C, and D) are not related to the purpose of the Plimsoll mark.
