Life aboard a narrowboat offers freedom, adventure, and connection with nature. But staying connected to the digital world presents unique challenges when your home constantly moves through rural canals and waterways.
Traditional fixed-line broadband obviously won’t work when you’re cruising between moorings. Yet remote work, streaming entertainment, video calls with family, and basic internet access remain essential for most liveaboards.
This guide compares every viable broadband option for narrowboat living in 2026, with real costs, actual performance data, and honest assessments of what works where.
The Narrowboat Internet Challenge
Narrowboats face connectivity obstacles that landlubbers never consider:
Constant movement – Your “address” changes weekly or daily
Rural locations – Canals deliberately avoid urban infrastructure
Metal construction – Steel hulls block mobile signals
Limited power – 12V systems and solar panels restrict equipment
Space constraints – No room for large antennas or equipment racks
Solutions must be portable, power-efficient, and work in remote areas with weak signal strength.
Starlink: The Game-Changer for Boat Life
Starlink transformed narrowboat connectivity when it launched mobile plans. Low Earth orbit satellites provide coverage anywhere in the UK with clear sky view.
Starlink Roam Plans for Narrowboats
Starlink Roam (formerly Starlink RV)
– Cost: £75/month + £449 hardware
– Speed: 25-100 Mbps download, 5-15 Mbps upload
– Coverage: Entire UK, Europe, worldwide
– Data: Unlimited (fair use policy applies)
– In-motion use: No – must be stationary
– Power consumption: 50-75W average
Starlink Mini Roam
– Cost: £75/month + £299 hardware
– Speed: 50-150 Mbps download, 8-20 Mbps upload
– Coverage: Same as standard Roam
– Data: Unlimited (50GB high-speed priority)

Real-World Narrowboat Starlink Performance
Based on boater community reports:
Best case (rural mooring, clear sky): 100-150 Mbps
Typical (semi-rural canal): 40-80 Mbps
Worst case (tree coverage, poor weather): 10-25 Mbps
Outages: 1-2% of time in heavy foliage areas
Power consumption matters significantly on boats:
– 12V inverter systems: 40-50W draw from Starlink Mini
– Requires ~30-40Ah battery capacity daily
– Needs 100-150W solar minimum to sustain
Starlink Setup for Narrowboats
Dish mounting options:
Most liveaboards use portable solutions allowing quick pack-up when moving moorings or going through low bridges.
Power setup:
– Connect directly to 12V system via DC-DC converter
– OR use 230V inverter (less efficient)
– Budget 50W continuous power minimum
– Consider dedicated lithium battery for internet equipment
When Starlink Works Best on Narrowboats
Ideal conditions:
