What is the maximum passenger capacity of a vessel with one radiophone in its lifeboat?

The maximum passenger capacity of a vessel equipped with one radiophone in its lifeboat is indeed 199 to 1,500 passengers. This range aligns with the requirements for passenger vessels as defined by maritime regulations, which categorize vessels based on their safety equipment and lifeboat capabilities.

The presence of a single radiophone indicates that the vessel has certain safety and communication provisions but is limited in the number of passengers it can safely accommodate while maintaining compliance with safety standards. It's important to recognize that such regulations are designed to ensure the safety of all onboard during emergencies, where communication is critical for effective evacuation and rescue operations.

The specific range of 199 to 1,500 accounts for larger vessels that have the capacity to carry significant numbers of passengers while still adhering to safety measures, including the equipping of suitable lifeboats for communication purposes.
