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.

Why is there a plimsoll line?
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 representative of a ship's owner on board a merchant ship?
Legally speaking, the owners representative on board is the Captain of the ship, properly referred to as the Master.
Why did ship owners want to overload their ships?
So they didn't have to make two journeys.
What is the reason behind that a ship sinks to a great depth in river water than in sea water?
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. Plimsoll fought for years to pass alaw, the Merchant Shipping Act of 1876,Floator Sink?How do captains know howto safely load their ships?Photo: This is the PlimsollMark on the port (left) sideofBalclutha. 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).
Why dosent a ship sink?
The bouyancy of the vessel keeps it afloat. As long as the force of bouyancy is larger then the mass of the ship it will stay afloat.
Why did Samuel plimsoll force ship people to overload there ships?
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.
Where can you find a plimsoll line?
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.
What is another name for a ship's load mark?
It is known as the plimsoll line, originally called the plimsoll mark.
What is on the side of a ship?
The gunwales, the anchors, the name, and the Plimsoll line.
What thewhite line is called on the side of a ship?
The lines drawn around the hull of a ship near the water-line is called a "Plimsoll line". This horizontal line is easily seen when the ship is empty and therefore riding higher out of the water. The more cargo loaded into ship the deeper it sinks into the water, and a ship can only be loaded with cargo etc down to this line and no furthur. Before its introduction there was no safe-loading-line on a vessel to prevent overloading by unscrupulous owners.
How do ships use Archimedes principle?
Archimedes principle led to the Plimsoll Line, which is marks painted near the bows of a ship. Basically, a ship on salt water floats higher and can carry more cargo. While a ship on fresh water will float lower and can safely carry less cargo. Samual Plimsoll introduced the Plimsoll Line to solved the hazard of capsizing posed by overloading a ship.
What happens if the plimsoll line is below the level of the water?
The plimsoll line is a reference mark painted on the bow of a ship. If the line is below the water level, the ship is overloaded. There are lines for when on fresh water and when on salt water.
What side is the plimsoll mark on a ship?
There is one on each side, port and starboard.
Why are plimsoll lines important?
To tell how high or low the ship is resting in the water. Also by examining the plimsoll line you can see how heavy a load is that the ship is carrying and is sometimes used as a warning against overloading.
What was the original name of the line on a ship showing the level to which it could be loaded?
Its called the Plimsoll line. It shows how laden the ship is.
What is a plimsoll mark on a boat and why is it on there?
Any of a set of lines on the hull of a merchant ship that indicate the depth to which it may be legally loaded under specified conditions. Also called load line, Plimsoll line.
What happens to the water level when the ship is loaded?
The ship becomes lower in the water. See the Plimsoll Line. ______________ The ship settles in the water at the point where the volume of the ship under the water i.e. the weight of the water it displaces is equal to the weight of the ship. ______________ I rather think I said that, though in fewer words; see the Plimsoll Line, probably the simplest invention in human history. Refer to the Merchant Shipping Act of 1875 (British Parliament).
