For decades, serious internet at sea meant VSAT: a stabilized dome on the mast, a five or six figure hardware bill, an airtime contract priced like a second crew salary, and speeds that made a video call an event. Starlink Maritime ended that era in a single product cycle. The Flat High Performance terminal is a flat panel, 575 by 575 millimetres and under 6 kg, that bolts to a radar arch or mast and delivers broadband that owners describe as like being at home.
The hardware
The terminal operates across Ka and Ku bands with IP54/IP56 ingress protection and an operating range of minus 30 C to 55 C. There is no moving dome to stabilize and no below-decks rack of modems in the basic installation. Coverage is global excluding polar regions, served by a constellation of more than 5,000 satellites, which is why the service works mid-ocean rather than only near shore, the historical weakness of cellular-based systems.
The pitch is high-speed broadband at sea: streaming, video conferencing, and full remote work from the anchorage, without a stabilized dome or a VSAT contract. It has quietly changed crew welfare as much as owner convenience: a connected crew is a retained crew.

The verdict
Starlink Maritime is now standard fit on new builds from 30 metre day boats to superyachts, and it is the single highest-value technology upgrade an existing yacht can receive. The caveats are real but narrow: it is a best-effort consumer-derived network rather than a contracted enterprise SLA, and heavy-weather performance and contention in crowded anchorages deserve honest discussion with the installer. For the overwhelming majority of owners, it is simply transformative.
What we have and have not done
This review is based on published specifications and reseller documentation. Yacht & Ocean has not independently measured throughput. Hardware and plan pricing should be confirmed on starlink.com/maritime before purchase; reseller plans cited here start at US$285/month.
The hardware
The Flat High Performance terminal is 575 by 575 by 41 millimetres and weighs 5.9 kg without cable, which is why it mounts on a radar arch or mast where a stabilized dome used to sit. It works in Ka and Ku bands, carries IP54 and IP56 ingress ratings, operates from minus 30 to 55 degrees Celsius, and is FCC certified. Coverage is global excluding the polar regions, served by a constellation of more than 5,000 satellites.
The commercial terms matter as much as the hardware. Published reseller plans run from a Priority 40 GB plan at US$285 per month to 1 TB at US$425 and 2 TB at US$750, with a six-month minimum term and a US$600 early termination fee on some reseller terms. Official pricing should be confirmed on starlink.com/maritime before committing; reseller storefronts are not the price list.
Why the VSAT era ended
The old regime was a stabilized dome, a six-figure hardware bill, and a service contract priced like a second crew salary. Starlink replaced it with a flat panel the size of a coffee table, no moving parts to stabilize, and consumer-grade subscription economics. The installation is a radar-arch mount and a cable run, not a shipyard project, which is why the terminal has spread from new 30-metre builds to refits of twenty-year-old yachts in a single product cycle.
