Which statement is true regarding the GMDSS operations?

The statement that GMDSS ensures greater safety through improved distress communication capabilities is true because the Global Maritime Distress and Safety System was specifically designed to enhance maritime safety. GMDSS incorporates various technologies and communication systems that allow for rapid distress signaling, immediate reception of distress alerts, and effective coordination during emergencies at sea.

The system uses satellite and terrestrial radio systems to ensure that vessels can send and receive distress messages from virtually anywhere, increasing the likelihood of timely assistance. This capability significantly improves the response times to distress situations, ultimately making maritime travel safer.

Other options mention various aspects of GMDSS, such as its operational limits or communication reductions, but the core purpose of GMDSS is its ability to facilitate effective communications in distress scenarios, which directly correlates to improved safety for mariners.
