Starlink Maritime vs. Roam: which plan is right for your boat?

Starlink Maritime is the professional-grade, purpose-built solution for vessels underway. It is the only plan officially designed and warrantied for the rigors of a marine environment.

1. Use case.Engineered for yachts, commercial ships, and recreational boats moving in coastal and open waters. The service provides priority network access, ensuring consistent, predictable performance even in congested areas.
2. Hardware.Utilizes the rugged Flat High-Performance terminal. This marine-grade dish is built to withstand saltwater spray, extreme temperatures, and high winds.
3. Performance.Downloads from 40–220 Mbps and exceptionally low latency, often under 50 ms — ideal for video conferencing, streaming, and real-time data access.
4. Coverage.Provides access to global ocean coverage, making it the only choice for true bluewater passages and international cruising.

Originally designed for land-based vehicles like RVs, Starlink Roam has become a popular "off-label" solution for some boaters. It works well within specific limits, but you must understand its trade-offs.

1. Use case.Best suited for boaters who primarily need internet while at anchor, moored, or at the dock. It is not officially supported for in-motion use at sea.
2. Hardware.Uses the standard consumer-grade dish. This hardware is not warrantied for a marine environment and is susceptible to damage from saltwater corrosion.
3. Performance.Service is provided on a "best effort" basis. Your connection may be deprioritized and slowed down in favor of Maritime or Residential users, especially in busy anchorages or marinas.
4. Coverage.Roam plans are limited to use on land and in coastal waters, typically within a single continent. Not designed for open-ocean crossings.

Performance & reliability. Maritime offers priority data access for consistent, predictable speeds with downloads from 40–220 Mbps and latency under 50 ms. Roam is "best effort" — performance while moving at sea is not guaranteed, and it works best at anchor, at the dock, or on inland waterways.

Hardware & durability. Maritime uses the Flat High-Performance terminal built for marine environments and designed for permanent, secure installation. Roam uses the standard consumer dish, which is not warrantied for marine use and requires custom mounting solutions for vessel safety.

Monthly cost & data. Maritime plans typically start around $250/month for 50GB of priority data. Roam starts around $150/month with regional and global plans offering unlimited data on land, subject to deprioritization.

Upfront hardware cost. Maritime's marine-grade terminal is around $2,500. Roam's standard kit is around $600.

Choose Starlink Maritime if:

1. Open-water cruising.You need reliable, high-speed internet while cruising in open water or offshore.
2. Mission-critical use.Your connectivity is essential for remote work, navigation, safety, or communication.
3. High-bandwidth demands.You require the best possible performance for streaming, video calls, and other high-bandwidth applications.
4. Permanent investment.You want a permanent, professional-grade solution that is built to last and adds value to your vessel.

Starlink Roam may be a fit if:

1. At-anchor use.You primarily boat on inland waters or the Long Island Sound and use the internet mostly when docked, moored, or at anchor.
2. Budget priority.A lower monthly cost is your top priority and you accept the performance trade-offs.
3. Casual browsing.Your internet needs are not mission-critical, and you understand this is an "off-label" application.
