At 1112hr a call was received from a 5m Trailer Boat wih1 POB .The boat was at the 20m mark off the Radio Mast with a flat battery and needed assistance.The sea conditions were good with 9-11kt wind from the NW and a 1m swell.An All Stations call was made and a good samaritan responded.An attempted jump start was unsuccessful so the boat was towed back to Whakatane.Both boats were safely back in port at 1354hr.A big thank you to the good samaritan.
