They are called Plimsol Marks! They are put on the side of the ship and show the safe load that the ship can carry in any particular type water! See fresh water has less bouyancy than saltwater so the ship for the same load sits lower in the water in fresh water than in salt! Likewise the temperature of the water controls the bouyancy and the insurance companies have at least one special route it is labled NAW = north atlantic winter !
FW = fresh water NA = north atlantic TF = tropical fresh water TS = tropical salt water
In addition there will be ABS or LLB or other initials indicating the underwritting company that supervised the construction of the ship! (american bureau of shipping or lloyds of london)
These markings are located mid ship in the center of rotation !
Fore and aft are painted on actual foot depth markings showing
the water the ship is actually drawing! These are just draft lines!

Plimsoll Lines.Loading mark painted on the hull of merchant ships, first suggested by the 19th-century English politician Samuel Plimsoll. It shows the depth to which a vessel may be safely (and legally) loaded.

That line bears the name of the man in the British Parliament who secured the legislation mandating it use. It is called the Plimsoll line, and no ship was to be loaded with cargo beyond that line by a law passed in 1872 (I think).
This law was put on the books because of the practice of ship owners of taking rotten and decrepit hulls, loading them with cargo to the gunnels, then insuring them for more than the value of the cargo and sending them into the Indian Ocean in Monsoon season. To hell with the crewmen, we're talking pounds sterling here.
Oh, no. Corrupt business men antedate the current American crop. In England they were nearly always Tories, And it was Liberal figures who passed legislation of this sort when Gladstone was PM.

the question asked what are the numbers that show how much the ship is drawing............those are "draft marks".........Plimsoll lines show the minimum freeboard allowed for various seas and various seasons, but don't tell you that there's 25 or 36 or 19 feet of ship sticking down at any particular moment

They're called the Plimsoll Line(s). named after Samuel Plimsolll who 'invented' them.
The same name was applied to PT shoes (in the UK anyway), because the line around the sole looked similar to the Plimsol line on a ship.

Load line or you may have heard from the early introduction form of the "Plimsoll" line. It is basically an indicator passed in maritine legislation to indicate the loading of the vessel
