Summer DWT: 18.712 t (Plimsoll Line) ?

"Different Plimsoll Lines
As already seen in the above diagram, there are various load lines that keep changing with the weather. There are summer load lines, winter load lines, tropical water load lines and fresh water load lines. The load lines can change with the density and the temperature of the water. This is because the temperature and the density also affect the buoyancy. The buoyancy of the water is the main factor that determines the load line.
There is also a concept of timber load line marks. These Plimsoll lines can be applicable to a ship only when the vessel has a forecastle of at least 0.07 of the length of the vessel. A raised quarter deck is also required if the length of the ship is less than one hundred meters. This Plimsoll lines allows the ships to carry extra timber as cargo."
