Wi-Fi Onboard: How Seafy Works on Corsica Ferries, Grimaldi Lines and GNV
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.

Seafy Coverage and Technology
Where it’s available: All Corsica Ferries/Sardinia Ferries, Grimaldi Lines and GNV* routes. *GNV Allegra, GNV Spirit.
How it works: Onboard routers connect to satellites (and, near coastlines, to coastal networks) to deliver Wi-Fi everywhere passengers gather—lounges, cafés, bars, and even cabins.
Performance: Satellite links powered by Starlink mean you can browse news, send emails, and share vacation photos without long waits. When fewer users are online (e.g. at night or in port), speeds approach those you’re used to on land.

Coverage and Speed Tips
Signal everywhere: Modern ships provide Wi-Fi to all public areas and cabins. For the strongest reception—especially for videoconferencing—head to lounges or bars where routers are concentrated.
Shared bandwidth: Speeds can dip when many passengers are online. For the smoothest experience, try off-peak times (late evening or during port stops).
Seamless handoff: As the ship moves from coastal networks to deep-sea satellites, Seafy automatically switches without dropping your connection (you might notice a brief pause).
In practice, chat and email remain reliably usable at all times; Digital Plus and Star Plus let you stream videos, make HD calls and even play online games with minimal lag.
