The Coast Guard, along with divers from the Contra Costa County Sheriff's Marine Unit and a helicopter, searched for San Francisco man Harry Lee, 51, after a Good Samaritan spotted Lee's 20-foot recreational fishing boat adrift in the Delta with no one on board at 2:16 p.m., according to the Coast Guard.
The keys were still in the ignition and the engine was off.
Though the Coast Guard suspended its search Saturday at 10:37 p.m., the marine unit continued the search for Lee at 8 a.m. today.
The search for Lee spanned approximately 46 nautical miles, the Coast Guard reported.
Lee is thought to have been wearing a manual lifejacket that must be inflated using a pull string.
A Coast Guard official said Saturday that it is unlikely that Lee inflated his lifejacket.
The Coast Guard recommends that boaters wear lifejackets that inflate upon contact with water.
