On the side of a large boat. It's positioned so that if it becomes under water then the boat is overloaded.
Do you mean the plimsoll line then if so it's found on the outside of a ship to determine the water line.
The plimsoll line was invented in the 19th centary by a british man named Samuel plimsoll
The Plimsoll line was created to prevent ships from sinking at sea.
because it was invented by a man called Samuel plimsoll It has saved many lines, he deserves to be honored for this idea.
He created the line so he named it after his self and wanted people to remember him
Plimsoll lines are marked on the side of a ship to indicate maximum loading. This varies slightly depending on the season and the ocean, depending what type of ship it is.
The plimsoll line is lower in salt water than in fresh
It is known as the plimsoll line, originally called the plimsoll mark.
On the contrary: The English politician and reformer, Samuel Plimsoll, devised the Plimsoll Line to prevent the overloading of ships. Ships float higher on salt water, and lower on fresh water. So the Plimsoll Line, painted on the bow of a ship, indicates the mark past which the ship must not pass - or it would be overloaded.
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.
