Deliberate mistake: Frank Beardsley moves his family into an old, defunct lighthouse, and subsequently makes a project of restoring the rotating lamp and actually running it. But lighthouses are navigational devices. Each one in use has its own unique, catalogued period, which identifies it and therefore helps a distant ship determine its own position. By running a "phantom" lighthouse, Frank, a career Coast Guard officer, risks confusing ships' navigators at sea. No real nautical officer would do such a thing.

Other mistake: When the family goes to the hardware depot to obtain home improvement materials, the twins manage to imbed the tines of a fork lift into a display of bagged sand over the Admiral's shoulders, yet the entire contents of the ripped bags drizzle down higher, onto his head.
