The man's body was found Sunday morning. He was later identified as 70-year-old John Patti of Palm Harbor.

Meanwhile, the Coast Guard says it worked with the Florida Fish and Wildlife Conservation Commission to make several rescues Saturday in Jacksonville waterways. Among those needing rescue were a two men and a 10-year-old boy whose boat became stuck on top of a jetty.

At this time boater's death appears accidental and not suspicious in nature.
