An unoccupied boat drifted into the Menai Strait after breaking her mooring.
The RNLI's inshore lifeboat from Beaumaris was called out at 5.25pm on Wednesday evening to ensure no one was on board the vessel, which was stopped by a passing pleasure boat with passengers onboard.
The unoccupied boat was towed by the lifeboat to the pier at Menai Bridge to prevent a navigational hazard with the mobile coastguard team from Bangor on hand to help with the berthing.
A RNLI Beaumaris spokesperson said: "The first informant did the correct thing in alerting the Coastguard to the situation. This meant our volunteer lifeboat crew were able to reach the location quickly, assess the situation and take the best course of action to prevent the situation worsening."
