PENSACOLA, Fla. (AP) - Authorities have responded to various boating emergencies across Florida throughout the holiday weekend.

The Pensacola News-Journal reports that radar was used to search for 4-year-old Logan Fontana, who fell from his grandfather's boat without a life jacket Saturday in Pensacola Bay.

In the Tampa Bay-area, a man died after jumping from a boat into a lake to save a dog that had jumped overboard.

The Pinellas County Sheriff's Office says the dog was returned safely Saturday to the pontoon boat on Lake Tarpon, but the Palm Harbor man disappeared underwater. John Patti's body was found Sunday.

The Coast Guard helped make several rescues Saturday in Jacksonville waterways, including two men and a 10-year-old whose boat became stuck on atop a jetty.
