RedactedNarrative: Two guys were duck hunting off of Harrington Beach Start Park when their batteries died out there.  The seas got rough and they began to take on water.  They called the Ozaukee dispatch and they got the ball rolling by getting the Coast Guard en route.  Warden happened to be in the area and talked with responders that were staged at Hwy D and the lake shore.  Warden told them that we didn't have to boat to respond with a couple of hours so CG was their best bet.  Warden talked with subject on the phone when they were out on the water.  They lost a PFD while frantically trying to get water out of the boat.  Warden told them to keep doing what they were doing and that he CG would be there within the hour.  CG got them out safely but subject had mild hypothermia.  They also had a separate layout boat that they towed out there.  CG was unable to recover the layout boat initially but now it has been recovered.
