When is Coast Guard assistance deemed necessary for a vessel that is aground?

Coast Guard assistance is considered necessary for a vessel that is aground primarily when the grounded vessel or crew are in immediate danger. This situation may involve conditions that could lead to serious harm or life-threatening scenarios, such as risk of capsizing, exposure to hazardous elements, or the potential for drowning. In such cases, the Coast Guard will prioritize safety and respond to protect lives and ensure the safety of those involved.

While being stuck or not moving (as stated in other options) may indicate a situation needing assistance, they do not necessarily mean the crew or vessel is in immediate danger. Similarly, bad weather can complicate situations but does not alone justify the need for Coast Guard intervention unless it also threatens the safety of the crew or vessel. The primary focus of the Coast Guard is to respond to emergencies where life and safety are at risk, aligning their resources according to the level of danger present.
