What is the significance of a ship's draft?

The significance of a ship's draft lies in its expression of the minimum depth of water in which the vessel can safely navigate without risk of running aground. The draft is the distance between the waterline and the bottom of the hull (keel), and it effectively represents how deep a ship sits in the water. This measurement is critical for maritime navigation, especially in shallow waters, harbors, and channels. Understanding a ship's draft helps in route planning, ensuring that the ship remains in navigable waters and avoids underwater obstacles.

Other aspects of a ship, such as its weight capacity, length, and speed capabilities, are separately measured by different parameters. While the draft can indirectly relate to a ship's weight when fully loaded, it does not directly indicate weight capacity, length, or speed. These other factors are determined by different specifications and engineering principles.
