  A Portaferry lifeboat crew was launched at about 11:15 BST and everyone was safely taken to shore at Killyleagh.
  Brian Bailie, lifeboat operations manager with Portaferry RNLI, said: "Once again all the hard work and hours invested in training has paid off with a happy ending.
  "With the start of the good weather and more and more craft taking to the water, it is increasingly important that everyone respects the water and makes all the necessary checks before going on the water".
target: Five men and two women were rescued by the RNLI after becoming stranded on two islands in Strangford Lough.
