What is the difference between forward and aft draft of a ship called?

The difference between the forward draft and the aft draft of a ship is referred to as trim. Trim describes how much lower the bow (front) or stern (back) of the ship sits in the water compared to the other. This measurement is crucial for stability and performance, as it affects the vessel's waterline, speed, and handling characteristics. Proper trim ensures that the weight distribution is balanced, which is essential for safe navigation and fuel efficiency.

Other terms listed may relate to broader aspects of ship stability and orientation, but they do not specifically measure the difference in draft between the bow and stern like trim does. For instance, list typically refers to the angle to which a ship leans to one side, while draft describes the depth of the vessel in the water overall. Therefore, trim is the precise term for the difference between the forward and aft drafts.
