What is the minimum number of two-way VHF radios required for SOLAS cargo ships between 300-500 GRT?

For SOLAS cargo ships with a gross tonnage (GRT) between 300 and 500, maritime safety regulations specify that there must be at least two two-way VHF radios. The requirement stems from the need for reliable communication in emergencies, ensuring that ships can maintain contact with other vessels and shore facilities. Having two radios not only provides redundancy in case one radio fails but also enhances the ability to communicate effectively while maintaining a watch on multiple channels.

This requirement reflects the broader safety ethos that governs maritime operations, ensuring that vessels are equipped to handle various situations, particularly in distress. Two radios allow for an operational setup where one can be used for general communication while the other is reserved for emergency channels, reinforcing the safety protocols established under SOLAS (International Convention for the Safety of Life at Sea).
