At 1049hr a 6m hard top boat with 4 POB reported that it had engine problems off Hawai/Tureri Point. The boat was in 21m of water and could only make way at 1kt. Weather conditions were good with a slight sea and 8kt wind from the west. An all staions call was made.  A good samaritan responded and offered to tow the boat back to Opotiki but wanted assistance to cross the bar.  At 1113hr Opac Rescue was called out and tasked to meet the disabled boat and tow it back to Opotiki. At 1155hr Opac Rescue reported that it had the boat under tow and at 1245hr reported that both boats were safely back in the river.  Many thanks to the
