North Yorkshire Police says officers will be increasing their patrols around the canal towpaths in the Skipton area after recent thefts from boats.
The force says day and night time patrols will be taking place, following reports of four boats being burgled on different days recently, with a number of household items taken.
Officers are investigating the offences and are working to establish whether the incidents are linked.
Craven Inspector Steve Breen said: “Being the victim of any sort of theft can be very upsetting. But for a lot of people who use the waterways their boat is also their home.
“We’ve increased patrols in areas around the canal to provide a high-visibility deterrent, as well as extra security for boat owners and anyone else who uses the waterways.
“These patrols will take place during daylight and hours of dark. I’d encourage anyone who has any concerns or questions about security to have a chat with our officers.”
