Draft marker on the hull of a ship.
The mark on a ship's side indicating how far it may be loaded is called the "load line" or "Plimsoll line." This line ensures that a vessel is not overloaded, which can compromise its safety and seaworthiness. The load line is usually marked with a horizontal line and various symbols or letters indicating the maximum allowable draft for different water conditions. Proper adherence to this mark is crucial for maintaining stability and buoyancy while at sea.

It is the deepest draft of a ship
It is known as the plimsoll line, originally called the plimsoll mark.
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.
To read the ship draft while waving on ship one needs the extra attention or else get injured or drop into the waters.
The draft of a boat determines minimum depth of water a ship can safely navigate. A shoal draft is a very shallow draft. In this case, shoal draft ballast is the sort of ballast that improves the stability of a shoal draft ship.

Buoyancy is the force that allows a ship to float on water, and the Plimsoll line is a reference mark on a ship's hull to indicate the maximum safe loading depth. By observing the Plimsoll line, ship operators can ensure that the ship is not overloaded, maintaining a proper balance between the weight of the ship and the buoyant force of the water to prevent sinking.
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.
A design draft is also known as a design draught. It is a complete drawing of the ship as it is expected to look when it is fully loaded.
