Eleven people have been rescued in three separate incidents off the Louth and Cork coasts.
In Louth, a boat with six people on board became stranded in a sandbank just outside Dundalk Harbour and had to be towed home.
In Ballycotton in Co Cork, a catamaran with four people aboard also had to be towed to shore when the skipper lost control of the vessel.
Meanwhile, a swimmer in Ballycotton bay was rescued by another swimmer. Both men are being treated in University Hospital Cork for injuries.
