RedactedNarrative: A family was renting a beach house.  Uncle and his 2 nephews were onshore when the minors went out on 2 kayaks.  From shore the uncle noticed the kayaks fill with water and they were struggling with the current and sea state.  He took another kayak in an attempt to rescue the boys while their mother called 911.  His kayak filled with water when he reached their location and capsized.  All were wearing PFD's and the uncle instructed the boys to hold onto their kayaks.  Plymouth Marine recovered the 3 persons in the water.  The boys and uncle were injured.   Uncle estimated the boys were in the water about 1/2 hour total.  He estimated he was in water about 15 minutes.  Kayaks were located and taken to shore.
