Maritime Connectivity

Best Satellite Internet for Boats & Maritime in 2026

Starlink Roam ($165/mo coastal, $250/mo global) has transformed maritime internet. It delivers 100 Mbps download with 20-60ms latency using a flat phased-array dish with no moving parts - replacing traditional VSAT systems that cost $5,000+/mo for a fraction of the speed. For recreational sailors and cruisers, Starlink is the clear choice. Enterprise vessels needing guaranteed SLAs should consider OneWeb or Viasat Maritime.

What Maritime Users Actually Need

Ocean Coverage

You need a provider that works offshore, not just at marinas. Starlink covers most waters between 60N and 60S latitude. Traditional VSAT covers polar routes too.

Motion Tolerance

Boat motion (pitch, roll, yaw) challenges satellite tracking. Phased-array antennas like Starlink handle this electronically. Traditional VSAT uses mechanical stabilized mounts.

Saltwater Resistance

Marine hardware needs to handle salt spray, humidity, and UV exposure. The Starlink dish is not formally marine-rated but performs well with proper mounting. Enterprise solutions offer marine-certified equipment.

Low Latency

Weather routing, chart updates, video calls home, and crew morale all need responsive internet. LEO satellites (20-60ms) are a massive improvement over GEO VSAT (600ms+).

Provider Recommendations for Boats

Best Overall

Starlink Roam - $165-250/mo

Starlink has completely disrupted maritime internet. The Roam plan at $165/mo covers your home continent's waters, while Global Roam at $250/mo works across all oceans. You get 100 Mbps download, 20-60ms latency, unlimited data, and a flat dish with no moving parts. The standard dish ($349) or Mini ($249) handles boat motion with electronic beam steering. Thousands of cruisers and liveaboards now rely on Starlink as their primary connection.

Best for Commercial Vessels

Starlink Business Maritime - $250-500/mo

For charter boats, fishing vessels, and small commercial operations, Starlink Business provides priority data access with higher speeds (up to 220 Mbps) and 25 Mbps upload. You get the same low latency but with less deprioritization during congested periods. The Business plan costs $250-500/mo and uses the same portable hardware - no professional installation needed.

Best Enterprise Maritime

OneWeb (Eutelsat) - Enterprise Pricing

For large commercial vessels, cruise ships, and offshore platforms needing guaranteed bandwidth SLAs, OneWeb's LEO constellation provides 50-195 Mbps with 30-70ms latency. Available through authorized maritime partners. Enterprise contracts include dedicated capacity, 24/7 support, and marine-certified hardware. The complete 654-satellite constellation provides reliable global coverage.

Legacy Option

Traditional GEO Maritime VSAT

Traditional maritime VSAT from Viasat, SES, and Inmarsat still serves large ships and vessels in polar waters. However, at 600ms+ latency, $2,000-10,000+/mo pricing, and 2-20 Mbps speeds, it is no longer competitive for most boats. The only remaining advantage is polar coverage above 60 degrees latitude and guaranteed bandwidth SLAs for mission-critical commercial operations. For recreational and most commercial vessels, Starlink has replaced VSAT entirely.

Practical Tips for Maritime Satellite Internet

1.

Mount as high as possible

The dish needs a clear sky view. On sailboats, mount on the stern arch or radar pole. On powerboats, the flybridge or radar arch works well. Higher mounting reduces spray exposure and sail/rigging obstructions.

2.

Protect from salt spray

The Starlink dish is not marine-rated. Salt buildup on the dish face degrades the signal. Rinse it with fresh water regularly. Some sailors use aftermarket radome covers for offshore passages. Keep the cable connections sealed with marine-grade waterproofing.

3.

Plan for power consumption

The standard Starlink dish draws 50-75W continuously. On a cruising sailboat, that is a significant load. Factor it into your energy budget. The Starlink Mini (25-40W) is better for smaller boats with limited electrical systems. Consider running it only when you need it.

4.

Check coverage before ocean passages

Starlink coverage varies by ocean region. The Atlantic between North America and Europe is well covered. Parts of the South Pacific and Indian Ocean may have gaps. Check the Starlink coverage map before extended offshore passages. You will likely lose coverage above 60 degrees latitude.

5.

Use a VPN for privacy and access

Your Starlink traffic routes through the nearest ground station, which may be in a different country than your flag state. A VPN ensures consistent access to streaming services, banking, and other geo-restricted content regardless of which ground station you connect through.

Frequently Asked Questions

Does Starlink work on the ocean?
Yes, Starlink works on the ocean in most coastal and offshore waters. The Roam plan ($165/mo) covers your home continent's waters, while Global Roam ($250/mo) works across all oceans where Starlink has satellite coverage. Coverage is best within about 60 degrees latitude north and south. Polar waters have limited or no coverage.
How much does maritime satellite internet cost?
Maritime satellite internet ranges from $165/mo (Starlink Roam for coastal sailing) to $5,000+/mo for enterprise VSAT solutions. Starlink Roam costs $165/mo for continental waters or $250/mo for global coverage. The Starlink Business maritime plan costs $250-500/mo with higher priority. Traditional maritime VSAT from providers like Viasat or OneWeb starts at several thousand dollars per month with enterprise contracts.
Can you use a regular Starlink dish on a boat?
Yes, the standard Starlink flat dish works on boats. It is a phased-array antenna with no moving parts, so it handles boat motion well. You need the Roam plan activated for maritime use. Mount it as high as possible with a clear view of the sky. The dish is not formally marine-rated, but thousands of sailors use the standard hardware with aftermarket marine mounts.
What happens to satellite internet in heavy seas?
Starlink handles moderate seas well due to its phased-array antenna design with electronic beam steering. In heavy weather with extreme rolling, you may experience brief signal drops as the dish temporarily loses its sky view. Rain fade is minimal with LEO satellites compared to GEO systems. The biggest issue is physical water and spray on the dish face - mounting it high and using a radome cover helps in rough conditions.
Is Starlink better than traditional maritime VSAT?
For recreational boats and small commercial vessels, Starlink is dramatically better and cheaper than traditional maritime VSAT. Starlink delivers 100 Mbps at 20-60ms latency for $165-250/mo, while traditional VSAT offers 2-20 Mbps at 600ms+ latency for $2,000-10,000/mo. However, large commercial vessels and cruise ships may still need enterprise VSAT for guaranteed bandwidth SLAs, dedicated capacity, and global polar coverage.
