Starlink Maritime is not the same product as the standard Starlink dish with the Roam Global plan — and the distinction matters significantly for anyone considering it. Maritime is a separate, higher-specification service tier designed for commercial vessels, offshore operations, and demanding marine applications. This guide explains what Maritime actually delivers, who it's actually for, and when the standard Roam plan is a better fit.
Starlink Maritime vs Starlink Roam Global — The Key Difference
Monthly cost~$200Custom pricing (higher)
Target userRecreational boatersCommercial vessels, offshore

Support tierStandardCommercial / priority
The key distinction: Maritime is a service tier, not a different satellite network. Both use the same Starlink satellites. The difference is prioritization, data allocation, and commercial support — you're paying for guaranteed throughput rather than best-effort residential service.
Who Starlink Maritime Is Actually For
Commercial fishing vessels:Need reliable connectivity for catch reporting, navigation data, crew welfare, and operational communication.
Offshore oil and gas:Mission-critical connectivity requirements that justify the premium pricing.
Commercial passenger vessels and ferries:Passenger WiFi service that needs consistent, high-throughput delivery.
Research vessels and scientific expeditions:Data-intensive operations with no tolerance for deprioritization.
Who Starlink Maritime is NOT for: Recreational sailboats and powerboats. A $200/month Roam Global plan on a standard or Mini dish delivers excellent performance for recreational cruisers at a fraction of Maritime pricing. The Roam Global plan is the correct product for the vast majority of recreational marine users.
Coverage at Sea
The same coverage map applies to both Maritime and Roam — Starlink's satellite network coverage. As of 2026, coverage extends across all major sailing routes in the Northern Hemisphere, the North and South Atlantic, Pacific, and Indian Ocean. Coverage at polar latitudes (above ~75° North and South) remains limited. Always check Starlink's current coverage map before offshore passages in high-latitude or Southern Ocean routes.
Best Marine Mounting Hardware
Marine-Grade Mount for Starlink — Commercial and Offshore
Heavy-duty marine-grade mount for permanent deck or superstructure installation on commercial and larger recreational vessels. 316 stainless hardware throughout, designed for offshore conditions including spray, UV exposure, and vessel motion at sea. Accepts standard Starlink High Performance and standard dish profiles. Through-deck version includes backing plate for fiberglass and aluminum deck substrates. For serious marine installations where the mount will be permanently exposed to saltwater conditions.
Material: 316 SS marine grade | Application: Commercial, offshore
Saltwater-Resistant Cable Conduit for Starlink Marine Installs
UV-stabilized, saltwater-resistant cable conduit for routing Starlink cables on vessel exteriors. Protects the cable from UV degradation, saltwater exposure, chafe against rigging and deck hardware, and mechanical damage from crew foot traffic. Essential for any permanent above-deck cable run on a vessel operating in saltwater environments. Cut to length, secured with stainless cable ties or screws.
Material: UV-stabilized polymer | Use: Above-deck cable protection
Installation Considerations for Vessels
Vessel motion and satellite tracking:Starlink's standard dish and High Performance dish both handle vessel motion well for recreational speeds. At high vessel speeds (30+ knots), the dish's tracking may lag momentarily during sharp course changes — typically self-correcting within seconds.
Vibration:Commercial vessels with large diesel engines create sustained vibration that can work mounting hardware loose. Use thread-locking compound (Loctite 243) on all mount bolts. Inspect monthly.
Antenna height:Higher placement provides better sky view but increases windage and reduces vessel stability. On sailboats, keep the dish below the boom level to avoid sail interference.
Frequently Asked Questions
> Can I use a standard Starlink dish on a commercial vessel instead of Maritime?
Technically yes — the hardware is the same. The distinction is the service contract and support tier. Commercial operators often require the Maritime service agreement for insurance, compliance, and guaranteed throughput reasons. Large commercial operations should use the appropriate service tier.
> Does Starlink Maritime work in ports and harbors?
Yes — the same satellite network covers coastal and port areas. Maritime is particularly valuable at anchor or in port where crew welfare connectivity is important and the vessel may be in a location with no cellular coverage.
> What's the hardware difference for Maritime?
Maritime subscribers typically use the High Performance dish, which offers higher sustained throughput and better performance in challenging conditions than the standard Gen 3. The High Performance dish is available to both Maritime and standard plan subscribers — it's the service tier that's different, not exclusive hardware.
For commercial and offshore operators, Maritime's prioritized service and dedicated support justify the premium. For recreational cruisers, the $200/month Roam Global plan on standard hardware delivers excellent offshore performance at a fraction of the cost.
