Vessel trim - Even Keel

"Even keel" is a nautical term used to describe a ship that is floating in the water with a level trim, which means the draft (depth) of the ship is the same at both the bow and the stern. When a ship is on an even keel, it is balanced and stable in the water.

Maintaining an even keel is important for the safe and efficient operation of a ship, as an unbalanced ship can be difficult to control and may be more susceptible to capsizing or damage in rough seas.

When a ship is not on an even keel, it may need to be corrected by adjusting the distribution of weight on board, such as by ballasting or deballasting the tanks or adjusting the position of the cargo. Ship operators need to carefully consider and calculate the change in trim when making these adjustments to ensure that the ship remains stable and safe.
