Boat crime on the UK waterways: what is known, and what isn't

Checked against its sources on 20 Oct 2026.

Ask boaters what worries them and theft is near the top of the list. So how much boat crime is there on the UK’s inland waterways? The honest answer is that nobody knows.

The data gap

Police crime-prevention officers say accurate marine crime statistics are hard to come by. Marine crime is thought to be highly under-reported.

Part of the reason is that boats and kit are often left unattended, in isolated places, for long periods. Police say they often hear about a theft well after it happened, which makes evidence hard to gather.

So treat any confident figure for boat crime with care, including ones you see shared online.

What the sources agree on

Police, the Canal & River Trust and marine insurers broadly agree on the shape of the problem.

Whole-boat theft is rare. Craftinsure, citing the Canal & River Trust, says narrowboat thefts are rare and many stolen boats are later recovered. A Trust guide says its writer knows of only one narrowboat that disappeared completely from the network.

Theft from boats is the bigger problem. Break-ins target tech, tools, cash and solar panels. Batteries, generators, ropes and gas bottles are taken too. Police say outboard theft continues to be a problem, along with life rafts and electronic and GPS kit.

Place matters. Theft from boats and vandalism are more common in cities and in poorly lit areas, and along busy towpaths. Secluded moorings and temporary moorings carry more risk.

People help recover things. The Canal & River Trust says quite a few stolen goods have been found by searching local online classified sites, and that boat sightings help it trace stolen boats.

What The Boat Index’s own numbers show

On 20 October 2026, 1 of the 44,214 boats on The Boat Index had been reported stolen. That is not a measure of boat crime. It shows only what has been reported to the Index. Very few thefts are reported here.

Why the framing matters

If you only prepare for the rare event, the whole boat vanishing, you miss the far more likely one: an outboard lifted off the stern, or a break-in while you are away. That is where sensible precautions pay off.

What reduces your risk

  • Lock lockers and hatches, and keep valuables out of sight.
  • Mark outboards and electronics with a forensic marking or etching kit recognised by Secured by Design.
  • Record serial numbers and take photos and a video. Keep copies at home and on the boat.
  • Moor in well-lit spots near other boats when you leave the boat unattended.
  • Get to know other boaters nearby.
  • Use physical and technical precautions together, not just one.

More detail is in protecting your kit.

If something is stolen

Call 999 if it is happening now or anyone is in danger. Otherwise call 101 or report it online, and get a crime reference number. Tell your insurer and the navigation authority.

Report every crime, even small ones. Police say this helps them target their resources. The Canal & River Trust makes the same point: police cannot put resources into a problem they do not know about.

Step-by-step help is in what to do if your boat is stolen.
