The Samuel Plimsoll of the Aberdeen Line

The Mark Map

The Plimsoll Mark diagrammed above is for the starboard side of a vessel; on the port side, the markings are reversed. The center of the disk is placed at the middle of the loadline. The lines are one inch think.

The letters signify:

LTFF		Lumber, Tropical, Fresh
LF		Lumber, Fresh
LT		Lumber, Tropical
LS		Lumber, Summer
LW		Lumber, Winter
LWNA		Lumber, Winter, North Atlantic
LR		Lloyds Register of Shipping

TF		Tropical Fresh Water Mark
F		Fresh Water Mark
T		Tropical Load Line
S		Summer Load Line
W		Winter Load Line
WNA		Winter Load Line, North Atlantic

The water could reach different parts of the line (see drawing above ) as its temperature and saltiness varied with season and location.
The basic symbol, of a circle with a horizontal line passing through its center is now recognised worldwide.
