Keep an Eye Out

For much of history, it was common for overloaded ships to succumb to high waves and sink. Without regulations, captains were incentivized to carry as much cargo as they thought the vessel could hold, frequently overestimating to the demise of their goods and crews. Over time, insurance companies and the international shipping community formalized requirements for marking the legal load limit on the outside of every ship. This load line, usually denoted as a horizontal line through a circle, will fall below the water if the vessel is overloaded. It is often known as the Plimsoll line after the British politician who championed its use. The buoyancy of a ship depends on the temperature of the water and whether it’s in seawater or freshwater, so most modern ships have a set of marks that serve as the load line in the various conditions through which they may travel.
