The Starlink Mini is making waves in the marine world—and for good reason. With its compact size, simple power requirements, and built-in Wi-Fi router, it's a game-changer for boaters who want reliable internet access on the water. Whether you're staying in touch with family, streaming HD content, or keeping connected with safety services during offshore trips, the Starlink Mini delivers performance where traditional cellular options fall short.

But before you install one on your vessel, it’s important to understand how the data plans work, how far offshore you can expect service, and how to get the most out of your setup.

Coverage Limits: What Happens Beyond 12 Nautical Miles?

If you're using the basic Starlink Roam plan ($80/month for 50GB), the Mini will only work reliably within 12 nautical miles (NM) from shore. This is perfect for inshore boating, weekenders, or casual trips where you're staying close to the coastline.

If you plan to travel beyond 12NM, you'll need to upgrade your plan to the Roam Unlimited ($195/month). After upgrading, you must also enable the "Global Priority" option in your Starlink settings. This takes around 5–10 minutes to activate and allows your Starlink Mini to connect offshore, including in international waters.

With this setup:

Base cost: $195/month
Global Priority data rate: ~$3 per GB
Billing: Pro-rata (you can downgrade at any time)

💡 Tip: If you’re only heading offshore occasionally, you can turn off Global Priority once you're back near shore and stay on the Roam Unlimited plan to avoid extra charges. This lets you stay flexible without needing to cancel or reconfigure your entire setup.

Mounting the Starlink Mini on Your Boat

The Starlink Mini is smaller and lighter than its predecessors, making it ideal for marine use—especially on smaller boats where space is limited. It runs natively on DC 12V, although we recommend using a power converter to run it at 24V–30V for best performance and reliability over time.

At Barji Marine, we offer custom flat mounts for the Starlink Mini, designed specifically for marine environments. These mounts can be installed on top of a flat surface or underneath one. In fact, we’ve successfully run the Mini through composite or wooden panels with only a minor drop in signal strength—great for sleeker or more concealed installations.

Real-World Performance on the Water

We’ve been using the Starlink Mini on our own boats and can confidently say—it’s a game changer.

Here’s what we've experienced:

Reliable Communication: Using Wi-Fi Calling, we’ve stayed in touch with friends, family, and even safety services during fishing tournaments—something VHF and cellular networks couldn’t handle.
Entertainment at Sea: In areas with no cell signal, we’ve streamed HD content from Netflix, YouTube, and more on our Smart TV with no lag or buffering issues.
Rough Seas? No Problem. The Mini holds a stable connection even in challenging sea conditions. Whether you’re trolling offshore or anchored in a swell, it just works.

Why Starlink Mini is the Future of Marine Connectivity

With traditional cellular options falling short once you're out of sight of land, satellite-based internet like Starlink is quickly becoming the go-to choice for marine users. The Mini makes that transition even easier thanks to:

Compact Size
Built-in Wi-Fi Router (no need for extras)
DC Power Compatibility
High-Speed Data, Even Offshore

As of this writing, the prices and data plan details mentioned are current—but Starlink frequently updates its offerings, so it’s always wise to double-check before making changes to your setup.

Final Thoughts

Whether you're cruising offshore, fishing in tournaments, or just enjoying some quiet time on the water, the Starlink Mini offers fast, reliable internet access that keeps you connected, safe, and entertained. Pair it with a Barji Marine flat mount for a secure, professional install that performs in real-world marine conditions.

If you're ready to upgrade your boat’s connectivity, the Starlink Mini is absolutely worth considering.
