Eight kayakers were rescued from Strangford Lough after getting into trouble on the water.
Two of the kayakers, who made their way to an island, called the coastguard around 10.30am on Saturday to report that others needed help.
Portaferry RNLI's volunteer crew launched and identified the two people who had raised the alarm, before travelling less than a mile to find four people with a Canadian kayak.
Three were in the boat, which had taken on water, while another was in the water holding on to the side of the boat.
The crew took all four on to the lifeboat, before recovering the pair who had raised the alarm.
Another two people were winched and assessed by paramedics from the coastguard rescue 199 helicopter.
The group was taken to Killyleagh by helicopter and lifeboat and all were checked on shore with no further treatment needed.
As well as the RNLI, the coastguard, ambulance crews and air ambulance were involved.
Belfast Maritime and Coastguard Agency issued general advice, saying: "We would always recommend that kayakers tell someone at home their passage plan including points of arrival and departure, timescale and any other relevant information."
