TEQUESTA, Fla. (AP) — NFL Hall of Famer Joe Namath is offering a $100,000 reward in the search for two teenage fishermen along Florida's Atlantic coast. 
 
 Perry Cohen and Austin Stephanos did not return as scheduled Friday from a fishing trip. Both are 14 years old, and they were last seen Friday afternoon in the Jupiter area buying fuel for their 19-foot boat. 
 
 Perry is Namath's neighbor in Tequesta. Namath held a news conference Sunday with the boys' families to announce the reward and appeal for information that could help the search. 
 
 Namath said both boys are skilled boaters. He said, "We've got to believe in their wherewithal." 
 
 Coast Guard air and sea crews have expanded their search farther north along the coast. The search so far has covered over 14,000 square nautical miles. 

 The overturned boat of two teens missing since Friday was found Sunday afternoon. 
 
 The search for Austin Stephanos and Perry Cohen continues.

 Original reports said the boat was found off Jacksonville. 
 
 The U.S. Coast Guard said the boat was found 67 miles off Ponce de Leon Inlet in Volusia County. 
 
 The boat cover was missing and one personal flotation device was still on board. 
 
 The boat will be anchored in place while search and rescue efforts continue.

 Perry and Austin, both 14, were aboard the 19-foot white single-engine boat. 
 
 The teens were last seen around 1 p.m. Friday after buying $110 worth of fuel at The Jib. 
 
 Perry and Austin left shore en route to the Bahamas. 
 
 The disappearances were alerted to Tequesta police at about 5 p.m. 
 
 Tequesta officers, along with the Palm Beach and Martin County sheriff's offices, the Florida Fish and Wildlife Conservation Commission and the U.S. Coast Guard, searched through the night for the teens. 
 
 The U.S. Coast Guard said it had covered 25,000 nautical miles as of Sunday night. 
 
 Pam Telvi Cohen, Perry's mother, said there is a $100,000 reward for the boys' safe return. 
 
 The families held a news conference Sunday morning thanking the public for their support. They also thanked the Coast Guard. 
 
 "The commitment (of the U.S. Coast Guard) has been fantastic," said Nick Korniloff, Perry's stepfather. 
 
 Football Hall of Famer Joe Namath is a neighbor of the families and joined them at Sunday's press conference.
– On Friday afternoon, Austin Stephanos and Perry Cohen bought $110 worth of gas for their 19-foot fishing boat and set off from Jupiter, Fla., in the direction of the Bahamas, in what NBC News reports is the last sighting of the two 14-year-olds. The two boys were reported missing when they failed to return that evening, reports WPBF, and the US Coast Guard says it has since searched nearly 15,000 square nautical miles for the pair. The boys' families don't believe they would have tried to reach the Bahamas; the AP notes that neighbor Joe Namath is offering a $100,000 reward. "The commitment (of the US Coast Guard) has been fantastic," Perry's stepdad tells WPBF. A Coast Guard rep says the boys were ill-equipped to be out overnight, and that the search has shifted north in the belief that their boat is disabled and drifting.
