Which statement about GMDSS-equipped ships is false?

The assertion that ships must have the required equipment inspected at least once every five years is incorrect. In fact, GMDSS regulations stipulate more frequent inspections. Typically, GMDSS equipment must undergo a shore-based maintenance program, which is typically mandated to be performed at least every 12 months, ensuring that the equipment remains functional and compliant with safety standards. This requirement underscores the importance of maintaining operational readiness for safety communications in emergency situations.

In contrast, the other statements adhere to established GMDSS regulations. It is permissible for a conditional or partial exemption to be granted for a single voyage outside a suitable sea area, acknowledging the varied operational circumstances ships may encounter. Additionally, the regulations indeed encompass all passenger vessels, irrespective of their size, and cargo ships of 300 gross tons and above, reflecting the comprehensive safety measures aimed at protecting lives at sea. Furthermore, the requirement for at least two crew members to hold a GMDSS Radio Operator's license guarantees that trained personnel are available to manage emergency communications and radio operations onboard.
