Katherine Given, the harbor master at Belfast Harbor, said the giant yellow duck, estimated to be about 25 feet tall, appears to be anchored in the shallow part of the harbor.

A lot of people want to keep it here." Given said she isn't in any hurry to get rid of the surprise visitor. "If it was in the middle of the mooring field, it could be kind of a navigational hazard," she said. "Where it's in the shallow water, it's not bothering anybody."
