VOLUSIA COUNTY, Fla. -

The search for a missing Florida man has entered its third day with no sign of him or his boat.

Investigators with the Florida Fish and Wildlife Conservation Commission, the Coast Guard and deputies are continuing the search for Enrique Bernardo Hernandez Rubio on Saturday.

The 48-year-old Apopka man left home Wednesday and is believed to have launched his boat from a ramp in the Intracoastal Waterway near New Smyrna Beach for a test ride and to possibly go fishing.

He was reported missing early Thursday. His family has been unable to reach him by telephone and found his truck and boat trailer, but not the vessel, at the ramp.

Authorities say they are conducting a full-scale search and rescue operation with helicopters and boats from multiple law enforcement agencies.
