If you’re living aboard a narrowboat or planning to cruise the UK canal system long-term, a reliable internet connection is more than a luxury—it’s a lifeline. Whether you’re earning a living on the move, bingeing your favourite shows, checking in with loved ones, or navigating tricky stretches of towpath, getting internet access on a narrowboat comes with unique challenges.
Let’s face it—steel hulls are basically Faraday cages, and rural Britain isn’t exactly known for blanket 5G coverage. Add the slow trundle of canal life and unpredictable mooring spots into the mix, and you’ve got a recipe for patchy signal at best. But don’t worry with the right gear and a bit of planning, you can enjoy reliable, fast Wi-Fi aboard—without tethering your sanity to the next available marina.
This guide walks you through everything—from the best 5G routers to roof-mounted antennas and SIM plans designed for boat life. So, grab a brew, settle in, and let’s get you connected.

Why Narrowboaters Need Strong Internet
Life afloat is idyllic, but it doesn’t mean going off-grid completely. Modern boaters need reliable connectivity, whether for work, play, or peace of mind.
Real-World Needs for Internet Afloat
- Remote Work: Zoom calls from your floating office
- Streaming: Netflix and chill—canal-side
- Navigation & Alerts: CRT updates, stoppage notifications, and real-time weather
- Community & Family: Keeping in touch, sharing the view on Instagram, or just Googling “nearest chandlery open now”
Strong internet makes a huge difference in quality of life aboard—especially for continuous cruisers who can’t rely on marina Wi-Fi.

Step-by-Step Installation Tutorial
Not a tech expert? No problem. Here’s how to get your internet system up and running without hiring a marine electrician.
- Scout Your Mounting Spot: Look for a clear spot on the roof with minimal obstruction. Avoid placing antennas near steel chimneys or solar panels.
- Install the Antenna: Use a marine-grade bracket and waterproof gland. Drill with care—remember, narrowboats aren’t known for spare ceiling panels!
- Feed the Cable: Run the coaxial cable inside using a weatherproof gland or through an existing fitting.
- Connect Your Router: Plug in your antenna cables, power cable (12V or adapter), and pop in your SIM card.
- Configure the Network: Use the web portal to name your Wi-Fi, set a secure password, and activate dual SIM failover if applicable.
- Test Everything: Do a speed test, try a Zoom call, and stream some YouTube. If it works in the galley, you’re golden.
Buying SIM Cards for Narrowboat Internet
Buying the right SIM is like picking your canal route—it all depends on where you’re heading and how long you’ll be cruising.
Where to Buy
- Network Providers: EE, Vodafone, Three, and O2 often have online or in-store deals
- Retailers: Supermarkets like Tesco or Argos often stock SIMs with bonus data
- Online: Amazon and mobile plan comparison sites often bundle data deals
What Matters
- Unlimited Data: Look for truly unlimited plans (watch out for “fair use” small print)
- Tethering Allowed: Make sure your plan doesn’t block hotspot use
- Roaming Ready: Good for anyone taking their boat through Europe
Top Tip: Carry two SIMs (on different networks) and switch based on coverage—your signal bars will thank you.
Data Plan Comparison for UK Boaters
Your router is only as good as the SIM plan you feed it. Here’s a practical look at what’s currently on offer in the UK and how to choose the right provider.
Network Overview
Provider | Strengths | Weaknesses |
EE | Best rural/canal coverage | Pricier than others |
Vodafone | Balanced speed and coverage | Fewer unlimited plans |
Three | Cheapest for big data users | Patchy in remote stretches |
O2 | Good in cities | Poor rural canal coverage |
Tips for Choosing a Plan
- Go Unlimited: Avoid data caps that throttle your speed mid-month.
- Watch the Fine Print: Some “unlimited” plans still throttle video or tethered devices.
- Use Coverage Checkers: Look up CRT towpath postcodes on coverage maps before committing.
- Dual SIM = Backup: Use two networks to cover more ground—especially useful when cruising.
Signal Boosters and External Antennas
Here’s where things get fun. If your router is the heart of your internet setup, then your external antenna is its lungs—it pulls in the data-rich air you breathe online.
External Antennas: Your First Line of Defence
Mounting a high-quality antenna on your boat roof can make or break your setup. Without one, even the best router will struggle inside your steel hull.
Types of Antennas:
- Omnidirectional: Picks up signal from all directions. Ideal for moving boats or casual moorers.
- Directional (Yagi or Panel): Stronger, focused reception. Great for long-term moorings but requires pointing.
Installation Tips:
- Mount at the highest point you can reach—think mushroom vent or pole mount.
- Avoid metal obstacles like chimneys or solar frames that block signal.
- Use weatherproof glands and secure cables with UV-resistant clips.
Signal Boosters: Worth It?
Signal boosters can amplify a weak mobile signal to improve router performance—but they’re not magic boxes.
Legal Note: In the UK, only Ofcom-approved repeaters are legal. You also need permission from your network.
When to Use One:
- You’re moored in a fringe area with 1-bar signal.
- You’ve already got a good antenna and router but need a bit more punch.
What They Won’t Do:
- Create signal where there is none
- Replace the need for a decent antenna
Bottom line: A signal booster can help, but it’s the cherry on top—not the cake.
Troubleshooting & Maintenance Tips
Even with the best gear, things can go wrong. Here’s how to stay ahead of common issues and keep your narrowboat internet running smoothly.
Common Issues & Fixes
- Signal Drops: Check if your antenna is securely connected. Sometimes moving the boat slightly or rotating a directional antenna can fix it.
- Slow Speeds: Test both SIMs if you’re using dual SIM. You may have hit a data cap or throttling zone.
- No Power to Router: If you’re wired into a 12V system, check fuse boxes and battery voltage. For plug-in routers, test with a known working outlet.
- Overheating: Keep your router out of direct sun and away from radiators or stove flues.
Preventative Maintenance
- Reboot your router weekly to keep things fresh
- Check for firmware updates monthly
- Inspect external antenna cables for wear or water ingress
Real-World Examples
Emma & Pete – Full-Time Cruisers
This creative couple run a media business from their narrowboat year-round. Using a JuiceBox AX3600, dual SIMs (EE and Three), and a roof-mounted antenna, they’ve managed Zoom calls from moorings as remote as Foxton Locks.
Jack – London-Based Freelancer
Jack lives aboard full-time but sticks mostly to the capital. His Puli AX router runs off solar, and he switches between Three and Vodafone depending on mooring. “It’s faster than my old flat in Zone 4,” he laughs.
Sarah & Tom – Weekend Wanderers
These two use their narrowboat for weekend getaways. They installed a JuiceBox 2540 with a Poynting antenna. “It’s plug-and-play and works like a charm,” says Tom. “We stream Match of the Day with no buffering.”
FAQ
Can I use Starlink on a narrowboat?
You can, but it’s overkill for most. Starlink dishes need clear sky views and draw a lot of power. Great for wide beam continuous cruisers with solar setups—not so much for minimalists.
Do I need an external antenna for boat Wi-Fi?
Yes. Without one, your signal will be spotty at best inside a steel boat. An external antenna is a must-have for reliable performance.
What is the best SIM-only plan for narrowboats?
Go with unlimited data on EE or Vodafone for the best mix of coverage and speed. Three offers great value but less reliability in remote areas.
Is 5G worth it on the canals?
Absolutely. Especially in and near urban areas, 5G can outperform home broadband. Just make sure your antenna and router support it.
Staying connected on the cut isn’t a luxury anymore—it’s essential. Whether you’re working from your floating office or just want to unwind with iPlayer after a day at the tiller, the right setup makes all the difference.
Start with a reliable 5G router, add a well-mounted external antenna, and power it with a flexible data plan. Whether you’re moored beneath a viaduct or tucked into a rural cutting, you’ll have signal strong enough to keep you online and worry-free.
So, here’s to remote work, streamable sunsets, and Wi-Fi that follows you wherever the water flows.
