People are being warned to be alert about the dangers of rising tides off the Cumbrian coast.
The Barrow inshore lifeboat was launched on Wednesday afternoon after a couple and their dog became stranded on Foulney Island by the incoming tide.
They had at first tried to walk back over the submerged breakwater but returned to the island and attracted attention by waving.
The RNLI said it had attended many such incidents and renewed its warnings.
Neither the couple or the dog were injured in the incident and were brought safely to the lifeboat station at Roa Island by two crew.
The RNLI said it wanted to take the opportunity to remind the public about the dangers of an incoming tide and recommended that they checked the state of the tide before going on to the island.
