What are the conditions, under GMDSS, whereby a ship is NOT allowed to depart from any port?

Correct Answer: Option A — The vessel is not capable of performing all required Distress and Safety functions.

Under SOLAS Chapter IV, a vessel must be capable of performing all required distress and safety functions to be considered seaworthy. If the radio installation is incapable of transmitting or receiving distress alerts, the vessel is in violation of international safety regulations and is prohibited from departing port.
