The Plimsoll line is a reference mark located on a ship’s hull that indicates the maximum depth to which the vessel may be safely immersed when loaded with cargo. This depth varies with a ship’s dimensions, type of cargo, time of year, and the water densities encountered in port and at sea.
How has the Plimsoll line saved lives at sea?
This simple graphic design has saved thousands of lives. The Plimsoll line shows the maximum loading point of the ship and lets a third party know, plainly and clearly, when a vessel is overloaded and at risk of sinking in rough seas.

It should also ensure adequate stability and avoid excessive stress on the ship’s hull as a result of overloading.
