Canadian Coast Guard search and rescue workers off Twillingate are preparing to wind down their search for a boater who is missing and presumed dead.
Acting superintendent of search and rescue Neil Peet said they have exhausted all possible search areas, and are forced to declare the man "missing at sea."
If they cannot find the man by 9:30 p.m. today the search will be officially called off.
Two young boys and another middle-aged man were also in the five-metre open boat which left Twillingate around 3 p.m. Saturday and did not return.
The bodies of the other three have been recovered.
Since the initial call came in around midnight Saturday, search workers have been scouring the area with Coast Guard vessels and a Cormorant helicopter.
Private boat owners in Twillingate volunteered and joined in the search, as well.
The names of the victims have not been released.
Peet said that the missing man's file will be handed over the the RCMP, who will treat it as a missing persons case.
