The Royal Bahamas Police Force is distributing flyers on John Batchelor of Ontario.
Spokeswoman Loretta Mackey said today that police are still treating his disappearance as a missing persons case.
Police boarded Batchelor's nine-metre sailboat last week after it had been sitting for several days with no sign of the owner.
The boat appeared to have been ransacked but there was no one on board but a malnourished dog.
The dinghy was attached but a swim ladder was down.
