What are two consequences of the draft of a ship?

The draft of a ship refers to the vertical distance between the waterline and the bottom of the hull (keel). This measurement is crucial as it significantly impacts a ship's operational capabilities. The correct choice emphasizes two main consequences of the draft: the depth of water needed for the ship to float and its potential changes with loading.

The depth of water needed for a ship to float is directly correlated to its draft; if the water is shallower than the draft, the ship will run aground. This is especially important when navigating in ports, docks, or shallow areas where depth must be sufficient to accommodate the vessel.

Moreover, the draft changes with the loading conditions of the vessel. As a ship takes on cargo, fuel, or ballast, its weight increases, which can lead to a deeper draft. Conversely, when cargo is offloaded, the draft decreases. This understanding is vital for maintaining safe navigation and ensuring compliance with stability criteria and load limits.

This focus on draft underscores its significance in maritime operations, particularly in safe passage and efficient cargo handling.
