An unmanned yellow paddleboat floating about 60 miles east of St. Augustine has the Coast Guard concerned there could be someone missing in the water.
Crews searched the area after watchstanders at the Coast Guard Sector Jacksonville command center received the report from the cruise ship Carnival Fantasy about 9 a.m. Monday.
The Coast Guard issued an urgent marine information broadcast and launched a helicopter crew and rescue boat.
By 1:30 p.m. the Coast Guard said the search was suspended. No one was found, but the paddleboat had marine growth and showed no signs of distress.
Anyone who recognizes the paddleboat or has any information about a missing paddleboat can contact the Coast Guard at (904) 564-7511.
