Answer
Do marinas have Wi-Fi?
Most modern marinas offer Wi-Fi, but quality varies. Liveaboards and remote workers typically supplement with a cellular hotspot.
What to expect
Coverage is best near the office and dock house. Speeds vary by marina — some advertise gigabit, others struggle past 10 Mbps under load.
Backup options
T-Mobile and Verizon home internet hotspots work well in many coastal markets. Starlink Maritime is increasingly common on liveaboard boats.
