Freeboard Mark (also Plimsoll Mark) - a marking consisting of: a freeboard circle and load lines indicating the maximum permissible draft of the ship in various circumstances and at various times of the year. In the case of this ship (in the photo) you can see that all rules and regulations were broken. The ship moored in the port of Crete (Mediterranean Sea, water with a density close to 1.025 - 1.026 t/cubic meter). The photo does not show even a fragment of the highest permissible line to which the ship can be loaded in the TROPIC, floating in water with a density similar to fresh water. Port authorities in most countries will not allow an OVERLOADED ship to go to sea. This always carries the risk of serious consequences. Several times I have encountered pressure from charterers or shippers who, driven by additional profit, wanted to force the cargo officer and captain to load an additional few hundred tons (for a coaster it was often even over 10% of the load capacity) or even over a thousand tons (when I was working on medium-sized bulk carriers. Fortunately, I worked with responsible captains.
