Why is this a thing?
Plenty of rides have blindspots like this, some much more glaring and much more dangerous. Typically under normal operations the boats do not carry such speed into the final turn, so any damage would be minimal and discovered during daily inspections. The ride had to have been operating in this condition for hours on end for the trough and that railing to get damaged to that extent. It's shocking to me no one who noticed it bothered to report it to the operators of the ride, especially whoever filmed it and shared the video to NJ.com. The operators are trained to stop a ride or stop using a specific unit as soon as a guest has any complaints about it.
