Maritime Connectivity 101: gigabits at sea

For decades, maritime connectivity meant VSAT — and VSAT priced bandwidth like saffron. Ten megabits at $18,000 a month works out to $1,800 per megabit. Crews rationed email. Guests gave up. Operations moved data by literally sailing it to port.

Then LEO changed the physics, and bonding changed the reliability. One Starlink terminal at sea is a good link with mood swings — beams hand off, the mast blocks the sky, weather moves through. Bond twelve to twenty of them with SpeedFusion and the mood swings average out into something a floating city can run on. That’s not a lab claim: a leading global cruise line runs 12–20 bonded terminals per vessel, HA Balance cores, 30+ gigabits of aggregate connectivity — with coastal 5G absorbed automatically near shore and legacy VSAT demoted to last resort.

The same pattern scales down: a 72-meter charter yacht runs it with twelve terminals; a workboat runs it with two and a cellular SIM. Sizing is the variable. The bond is the constant.

Maritime Connectivity 101 covers cost-per-megabit math, rain fade and how the bond eats it, crew/guest/operations network separation, existing VSAT contracts, and terabyte offloads that used to cost port calls. If your vessel still budgets connectivity like it’s 2015, start there.
