You can search online to find a nearby boatyard, or contact River Canal Rescue, who'll come out to you - and even bring tea and snacks along in case you're peckish.
If you're stuck for several days, or worse on a time limited mooring, make sure you contact our boat licensing, compliance and enforcement team to arrange to stay longer. Make a note of our customer services team number, 0303 040 4040, so you can call us even if you don't have internet access where you are.
You may need to tow your boat a short distance to a less popular mooring spot, and if the delay takes longer than you expected, you may need to pay an extended stay charge.
