FCC Exam Question: 1-6A6

By international agreement, which ships must carry radio equipment for the safety of life at sea?

A. All ships traveling more than 100 miles out to sea.
B. Cargo ships of more than 100 gross tons and passenger vessels on international deep-sea voyages.
C. All cargo ships of more than 100 gross tons.
D. Cargo ships of more than 300 gross tons and vessels carrying more than 12 passengers.
Correct Answer: D

Explanation: The International Convention for the Safety of Life at Sea (SOLAS) is the primary international treaty ensuring minimum safety standards in the construction, equipment, and operation of merchant ships. This agreement mandates the carriage of radio equipment, essential for participating in the Global Maritime Distress and Safety System (GMDSS). SOLAS regulations specifically apply to: 1. **Cargo ships of 300 gross tons or more.** 2. **All passenger ships**, which are defined by SOLAS as vessels carrying more than 12 passengers. These thresholds ensure that vessels most likely to face significant risks or carry a substantial number of people are equipped for effective distress and safety communications worldwide. Options A, B, and C provide incorrect tonnage values or omit specific categories of vessels covered by these crucial international safety regulations.
