What should be included in a distress message?

In a distress message, it is essential to include the vessel's name along with the nature of the distress. This information is crucial for rescue coordination and for the responding vessels or authorities to quickly assess the situation and determine the necessary response.

Including the vessel's name helps identify who is in need of assistance, while detailing the nature of the distress conveys the urgency and specific circumstances, such as if the vessel is sinking, adrift, or experiencing a fire. This comprehensive information facilitates a more efficient and effective rescue operation, as it allows for appropriate prioritization and allocation of resources.

The other choices lack critical elements. Relying solely on the vessel's name does not provide any context for the situation. Location coordinates alone provide geographical information but do not convey the urgency or nature of the emergency. Mentioning only the time of transmission excludes vital identification and situational details needed for a coordinated response.
