Draft marker on the hull of a ship.
When a ship crosses the Equator.
It is the deepest draft of a ship
It is known as the plimsoll line, originally called the plimsoll mark.
To read the ship draft while waving on ship one needs the extra attention or else get injured or drop into the waters.
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.
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.

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.
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.
