What does it mean when a vessel is described as being "aground"?

When a vessel is described as being "aground," it indicates that the boat is touching or stuck on the bottom of the water body, such as a river, lake, or ocean. This situation typically occurs when the water level is too shallow, preventing the vessel from floating freely. Being aground can lead to potential damage to the hull if the vessel is not designed for contact with the bottom and can leave the vessel immobile until it is refloated or moved to deeper water.

Understanding this term is critical for boaters, as running aground can pose risks not only to the vessel but also to the safety of its occupants. It may require immediate attention to either remedy the grounding situation or signal for help.

The other answer choices describe different circumstances that do not correspond with the definition of "aground." For example, sailing at top speed and being anchored in deep water both imply that the vessel is floating and maneuverable, while being legally docked suggests that the vessel is tied up at a dock without being in contact with the bottom. None of these situations involve the vessel being stuck or in direct contact with the bottom of the water.
