đ Key Concepts
⢠Plimsoll mark / Load line marks arrangement on the shipâs side
⢠Difference between fresh water marks (usually on one side of the vertical) and sea water / seasonal marks (on the opposite side)
⢠Order of seasonal marks from uppermost to lowest (Tropical, Summer, Winter, Winter North Atlantic)
đ Think About
⢠On the standard load line diagram, which side of the vertical line carries the fresh water marks, and which side carries the saltâwater seasonal marks?
⢠Starting from the top seasonal mark and moving downward, what is the correct sequence of Tropical, Summer, Winter, and Winter North Atlantic? Where does the line labeled F fall in that sequence?
⢠Is the line at F higher or lower than the summer mark, and would a colder seasonâs mark be higher or lower in the water?

Before You Answer
⢠Confirm which labeled lines (B, C vs. D, E, F, G) are on the freshâwater side and which are on the saltâwater / seasonal side.
⢠Verify from a standard Plimsoll diagram that the order from top to bottom on the seasonal (saltâwater) side is Tropical, Summer, Winter, Winter North Atlantic.
⢠Make sure you match the vertical position of F with the correct season in that sequence before choosing among AâD.
