The Coast Guard is searching for a possible missing person in the water on Block Island, Rhode Island.
They launched the search after a report of an unmanned dinghy making circles in Great Salt Pond around 1 a.m. Monday.
The Block Island harbormaster stopped the dinghy and found no one aboard.
Officials contacted the owner, who is safe and said the dinghy was moored at the pier Sunday afternoon.
So far a search for a different operator has come up empty.
Anyone with information is asked to contact Sector Southeastern New England at 508-457-3211.
