Weathernews launches offline navigation mode

New offline capability ensures ship masters retain access to stored weather forecasts and passage plans during connectivity interruptions

Weathernews has introduced an offline mode for its AI-powered SeaNavigator for Master service, enabling ship masters to access stored weather forecasts and passage plans when onboard internet connectivity is interrupted.

The new capability follows onboard trials conducted between February and April 2026, during which masters highlighted unreliable satellite connections as a significant obstacle to using live weather intelligence. Reported problems included weak VSAT coverage in the southern Hemisphere, latency exceeding 1,000 milliseconds and restrictions on satellite services in some coastal waters.

“Too many digital tools are still designed as though the network will never go down. Offline mode starts from the opposite assumption,” said Craig West, chief executive Europe at Weathernews. “If the link drops in the middle of a weather decision, the master still has the forecast, the planned route and a clear view of how current that data is.”
