In sailing a ship, fuel, cargo, food, drinking water, etc. on the ship are in designated cabins. When the articles are sailed, the draft and trim of the ship are all according to the design requirements, so that the stability of the ship is facilitated. However, in operation, these items are changed, some items are decreasing, and some items are increasing. For example: some fuels will gradually decrease due to the operation of the ship, and drinking water will also decrease gradually. Some cargo holds are either increasing cargo or decreasing cargo. These changes may change the original draft of the vessel or the front and rear loading capacity, and thus affect the sailing performance of the vessel.
