Staying connected at sea is now easy and within everyone’s reach.

Seafy is the onboard Wi-Fi service that lets passengers access the Internet during ferry crossings, available on Corsica Ferries (including Sardinia Ferries), Grimaldi Lines and Grandi Navi Veloci (GNV). Whether you want to chat with family, post on social media, or even work remotely, Seafy keeps you online from departure to arrival. Thanks to cutting-edge satellite technology (e.g. Starlink), the connection is both stable and fast, getting ever closer to the shore-based Internet experience.
