Intermittent tourist whistle is not a "private nuisance"

In a relatively unusual case, the Court of Appeals concluded that sounding a navigating whistle on the tourist riverboat operated in Frankenmuth does not constitute a private nuisance.  The resident who filed suit to limit or eliminate the whistle sounding was denied relief, even though the whistle is sounded almost ten time per hour during the 12 hours of operation and seven cruises daily.  In essence, the court held that the sound wasn't so obnoxious as to be unreasonable, given the Coast Guard regulations that applied and the location in a tourist magnet community.
