Plimsolls line indicates the draft of the ship and the legal limit to which a ship may be loaded for specific water types

and temperatures in order to safely maintain buoyancy, particularly with regard to the hazard of waves that may arise.

If a ship is riding too low in the water it will become dangerously unstable and could capsize.

Plimsolls line has various marking depends on salinity of water, season (winter or summer) and sea locations

The level of a ship in the water is affected by temperature and salinity as well as load.

Temperature affects the level because warm water provides less buoyancy, being less dense than cold water.

The salinity of the water affects the level, with fresh water being less dense than salty seawater
