It is known as the plimsoll line, originally called the plimsoll mark.
The Plimsoll line is there for safety's sake. It's to prevent overloading of a vessel.The Plimsoll line or Plimsoll mark is named for the 19th Century Englishman Samuel Plimsoll, who first suggested that it was necessary to have permanent line or mark on the hull of merchant ships to show the depth to which a vessel may be safely and legally loaded. This "load" line differs from the waterline, which shows where the unloaded vessel floats. The Plimsoll mark is important because if it is submerged due to overloading, it immediately shows that the vessel does not have enough freeboard (that part of the vessel that is out of the water) to be safe.
The Plimsoll Lines stopped owners overloading the ship, as it provided a 'load line' which could not be exceeded. i.e. when a ship goes to sea, the water line is never allowed to go above the plimsoll line.
a plimsoll line is on a boat so that everyone knows the mass weight that the boat can take, if you cross this line it is not safe and there is a possibility that the boat may sink
