What do the letters stand for on the Load Line?
The letters on the horizontal line through the center of the circle stand for the classification society, i.e.; AB is the American Bureau of Shipping, LR would be for Lloyds Register of Shipping, etc. The letters on the ladder lines to the side of the circle are as follows; TF is Tropical Fresh Water, F is Fresh Water, T is Tropical, S is Summer Season, W is Winter Season and WNA is Winter North Atlantic. Depending on what waters the ship is in at the time of loading, it cannot load above the corresponding mark.
