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.

equiring ships owners to putload lines on ships and to usethem. Plimsoll's idea, knownas the Plimsoll Mark, is stillused all over the world.Have you ever tried fl oating in the ocean?In your bathtub? Which was easier? Youmight have noticed it is easier to fl oat insaltwater than freshwater.It is easier for ships to fl oat in saltwater,too. Two properties of water -- temperatureand salinity (saltiness) -- aff ect how deep aship's hull will fl oat below the water's surface.Warm, salty water is easiest to fl oat in,but not all ships stay in warm, salty wateras they move cargo around the world. Howdo captains know their ships will stay afl oatfrom one port to the next?Imagine you are the captain of a giganticcargo ship. You loaded your ship in asaltwater port in Japan, traveled across theentire Pacifi c Ocean, and are heading to afreshwater port in the San Francisco Bay tounload.As you travel from saltwater to freshwater,your ship's hull will sink deeper into thewater. Your ship could be in danger if theload is too heavy. It could run aground,break a hole in the hull and, and, worstof all, leak fuel and oil into the water. Inthe 1860s, overloading was a big problem.Some ship owners fi lled their ships withmore cargo than they could safely carry.Over and over again these "coffi n ships"sank. Many sailors died and the cargo sankto the bottom of the sea. Some ship ownersdid not care if they lost a ship or two.Samuel Plimsoll (1824-1898) did care, andwas troubled by this thoughtless disrespectfor sailors' lives. He devised a simple line tomark on the side of a ship to show the lowestlevel it should sit in the water. Ownerscould safely load a ship until it reached thisline, but no further.The idea of load lines dates back to ancientGreece and Rome, but there were no lawsin Plimsoll's time requiring them to be onships.

The horizontallines show how deep a shipcan be loaded with cargo indifferent waters. If the shipwas in fresh water (FW), shecould be loaded (sinkingdown lower) until the waterwas even with the line belowFW. If she was in salt water,then she could be loaded tothe line below WNA (WinterNorth Atlantic).
