What type of calls are classified as 'distress'?

Distress calls are specifically defined as communications made in situations where immediate assistance is required due to an emergency. These situations can include, but are not limited to, instances such as vessels sinking, individuals overboard, or any scenario where life is at risk or significant damage to property may occur. The urgency of these calls is paramount, and they are treated with the highest priority by rescue services and maritime authorities.

The classification helps ensure that resources are allocated correctly in emergency situations. Other types of calls, such as routine communication, general safety inquiries, or transactional calls, do not convey an immediate threat to life or property and therefore do not fall under the 'distress' category. Such calls can typically wait without jeopardizing safety or requiring urgent response measures. This distinction is critical for maintaining effective communication protocols at sea, ensuring that distress situations are addressed swiftly to protect life and property.
