Final answer:
The AIS system broadcasts various technical details of a vessel for safety and navigation but does not typically include information about the vessel's cargo. Option D is correct.
Step-by-step explanation:
While underway, a vessel over 100,000 gross tons with an automatic identification system (AIS) is expected to broadcast all the information listed in the options except for the vessel's cargo. AIS primarily transmits technical details about the vessel, such as the vessel's length and beam, its draft, and navigation status. These details are vital for collision avoidance and maritime safety.
In contrast, specific cargo details are not typically broadcasted by AIS as they are not relevant to the system's primary purpose of aiding in maritime navigation and safety. While AIS does provide information like a vessel's destination, this does not typically include the current port unless the vessel is close to arrival.
While underway, a vessel over 100,000 gross tons with an automatic identification system (AIS) is expected to broadcast all of the following information every 1 to 10 seconds EXCEPT Vessel's current port. The vessel's length and beam, draft, and cargo information are all expected to be broadcasted.
