Whether you’re a weekend cruiser, a full-time liveaboard, or somewhere in between, staying connected on the water has become more important than ever. From checking weather updates to streaming Netflix or keeping up with work, internet access on boats is no longer a luxury—it’s a necessity for many. But how do you get reliable internet out on the open water? The answer usually comes down to two main options: cellular and satellite.
In this guide, we’ll break down everything you need to know about getting internet on your boat, including the pros and cons of each option, a side-by-side comparison table, and some visuals to help you better understand the systems involved.
Why Internet on Boats Is Different
Unlike getting Wi-Fi at home or in a coffee shop, internet connectivity on a boat presents a unique set of challenges:
- You’re often far from traditional infrastructure.
- Weather and water conditions can affect signal strength.
- You may move between different coverage zones.
That’s why boat internet solutions need to be more flexible and rugged than land-based systems.
Option 1: Cellular Internet for Boats
How It Works
Cellular internet relies on mobile data networks (like 4G LTE or 5G) to provide access. You can use a smartphone hotspot, a dedicated marine router, or even a signal booster to improve reception.
Equipment Needed
- Marine-grade LTE/5G router (e.g., Pepwave, Cradlepoint)
- External antennas for better reception
- SIM card with a data plan (preferably unlimited or high-cap)
Pros
- Affordable: Equipment and data plans are cheaper than satellite.
- Fast Speeds: Especially close to shore or in high-coverage areas.
- Easy to Use: Plug and play, and often compatible with smartphones.
Cons
- Limited Range: Usually only effective up to 20 miles offshore.
- Coverage Gaps: Remote areas or certain countries may have poor cellular service.
- Data Caps: Some plans throttle speed after a certain limit.
Option 2: Satellite Internet for Boats
How It Works
Satellite systems communicate with orbiting satellites to provide internet access almost anywhere on Earth. There are three main types: LEO (Low Earth Orbit), MEO (Medium Earth Orbit), and GEO (Geostationary Orbit), with LEO being the most modern and commonly used for recreational boats.
Equipment Needed
- Satellite dish (e.g., Starlink Maritime, KVH, Iridium)
- Mounting hardware
- Power supply and cables
Pros
- Global Coverage: Works far offshore and in remote locations.
- Consistent Connection: Not reliant on nearby cell towers.
- Great for Long Voyages: Ideal for bluewater cruisers or transoceanic trips.
Cons
- Expensive: Equipment and monthly fees can be quite high.
- Bulky Setup: Dishes and power requirements may be a challenge for smaller boats.
- Latency: Higher than cellular, though improving with LEO options.
Cellular vs Satellite: Quick Comparison
| Feature | Cellular Internet | Satellite Internet |
|---|---|---|
| Coverage Range | Up to 20 miles offshore | Global (including oceans) |
| Speed | Fast near shore (up to 100Mbps+) | Moderate to high (10–200Mbps) |
| Latency | Low | Medium to high |
| Cost | Low to medium | High (setup + monthly fees) |
| Ease of Use | Simple setup | More technical to install |
| Data Caps | Often yes | Varies by provider |
| Best For | Coastal cruising, liveaboards near shore | Ocean crossings, offshore work |

Real-World Use Cases
Weekend Cruisers
If you’re mostly near the coast and take short trips, a cellular setup with a booster may be all you need. You can stream music, check the weather, and even join Zoom calls with decent reliability.
Liveaboards
Living aboard full-time? A combination of cellular and satellite might give you the best of both worlds. Use cellular when near shore and switch to satellite when further out.
Offshore Voyagers
Sailing across oceans or exploring remote islands? Satellite is your only reliable option. While pricey, it’s the only way to maintain a connection far from land.
Tips to Maximize Your Boat Internet
- Use a Signal Booster: This can drastically improve your cellular signal.
- Combine Solutions: Use both satellite and cellular with a smart router that switches based on signal quality.
- Optimize Data Usage: Install ad blockers and use low-data settings on apps.
- Check International Roaming: If cruising across borders, make sure your SIM plan supports roaming.
Final Thoughts
Staying connected at sea is more feasible than ever, thanks to advancements in both cellular and satellite technologies. While no solution is perfect, understanding your cruising style and communication needs will help you make the best choice.
Whether you’re hopping between marinas or crossing the Atlantic, there’s an internet setup that can keep you in touch with the world—just be ready to balance cost, coverage, and complexity.
FAQs
Can I get internet in the middle of the ocean?
Yes, but only via satellite. Cellular won’t reach that far.
Is Starlink available for boats?
Yes, Starlink Maritime is now widely available and growing in popularity for its high speed and relatively low latency.
How much does boat internet cost?
Cellular setups can cost as little as $200 for equipment and $50/month for data. Satellite setups can exceed $5,000 for gear and $200+/month for service.
Can I work remotely from my boat?
Absolutely. With a good internet setup and careful planning, many remote workers live aboard while staying connected.
