Most modern boats offer Starlink or satellite Wi-Fi (often included or $5–$20/day). Coverage in remote areas can still be limited.
Wi-Fi on liveaboards has been transformed by Starlink in the last 2–3 years. Most quality operators have now installed Starlink antennas, providing fast (10–50 Mbps) internet across most ocean regions. Older satellite systems (V-Sat, Inmarsat) are slower (1–5 Mbps), more expensive, and less reliable, but still common on some operators.
Starlink coverage
Now active across the Caribbean, Mexico, the Mediterranean, the Maldives, most of Southeast Asia (Indonesia, Philippines, Thailand), parts of the Indian Ocean, and increasingly the Pacific. Galápagos, Cocos and Antarctica still have limited or no Starlink coverage but are improving rapidly. Confirm with the operator before you book if reliable connectivity matters.
Cost models
Three approaches: 1. Included free for all guests. Premium and luxury operators increasingly include Wi-Fi as part of the all-inclusive package. This is the gold standard. 2. Daily or trip pass. $5–$20/day, $30–$80/week. Settled in cash on the last evening or charged to your room. 3. Pay-per-MB or per-GB. Older satellite systems use this model. Expensive ($1–$5/MB) and only useful for emergency messaging.
Connection quality during diving
Starlink works best when the boat is stationary. During open-ocean crossings the antenna may temporarily lose lock and reconnect every few minutes. While diving, the boat is usually anchored and connection is stable. Don't expect to stream Netflix in 4K, but you can usually video call family, upload photos, and check email comfortably.
Bandwidth sharing
The Wi-Fi is shared among all guests on board. If 24 people are all uploading photos at the same time, individual speeds drop. Most operators set a fair-use cap (e.g., 5GB per guest per day) to prevent any single guest from monopolizing the connection.
Cellular data as backup
In the Maldives, Indonesia, Philippines, Mexico and the Caribbean, your home cellular SIM with international roaming or a local prepaid SIM works for the first 24–48 hours of the trip while the boat is still near shore. Once the boat moves to remote sites, cellular drops out and Starlink becomes your only option.
Emergency communication
Even on boats with no Wi-Fi, the captain has VHF radio, sat-phone (Iridium), and EPIRB for emergency communication 24/7. If you genuinely need to be reached for a family emergency, contact the operator's office and they will pass the message via the captain's sat-phone.
