Wow!! that is somehting AUSTIM!!
Many years ago I had the honor of checking a bridge that was impacted by one of those old type of excursion boats. This boat had smokestacks that were 20 feet if they were a foot. The river was well into flood stage and yet someone made the crass decision to go out that day!
If it weren't for the cassions of the bridge this boat may have met a similar fate. However it worked, those smokestacks didn't fair quite as well as they were bent in half!
