Coast Guard crews are searching for a man last seen aboard the No Bull, a 42-foot fishing boat.
The crew of the No Bull stopped fishing at midnight and Gary Kettlehut, 45, was last seen at the bow of the vessel approximately 78 miles northwest of Egmont Key.
Watchstanders received a relayed distress call at 7:15 a.m., Wednesday, reporting Kettlehut wasn't aboard the No Bull when the crew awoke at 6 a.m.
Sector watchstanders launched an MH-60 Jayhawk helicopter crew and an HC-130 Hercules aircraft crew from Air Station Clearwater. Coast Guard Cutter Hawk, an 87-foot Coastal Patrol Boat homeported in St. Petersburg, was diverted to assist in the search as well.
"At this time, the search area is approximately 100 square miles, starting at the point Kettlehut was last seen," said Lt. Michael Persun, a search and rescue coordinator at the sector.
Kettlehut was last seen wearing tan shorts with no lifejacket. Anyone with information leading to the whereabouts of Kettlehut is asked to contact Coast Guard watchstanders at 727-824-7506.
