GMDSS

GMDSS (Global Maritime Distress and Safety System) is the internationally regulated framework for maritime distress alerting, safety broadcasts, and emergency communications. It combines radio, satellite, and onboard alerting equipment so vessels can call for help and receive safety information at sea.

For boaters, GMDSS matters because it improves the chance that a distress message reaches the right authorities quickly, with position and vessel details where equipment allows. It supports safer offshore passages alongside good Marine Radio practice, correct use of VHF Radio, and coordinated Search And Rescue response.

GMDSS is not a substitute for seamanship, watchkeeping, or weather planning. Use reliable forecasts, routing, and onboard connectivity to reduce risk before departure; PredictWind tools can help crews monitor changing wind, wave, and route conditions while maintaining appropriate emergency communications.
