Unsure as to the nature. My guess is something to do with the boats propulsion system ? I am only guessing but when we finally got on, the front row was a "problem" (Cast Member's words) and they were only loading 2 people per row. We rode a boat with 4 people, and the family of 7 behind us had to be split into two boats. Even with that loading technique, the ride was up at 2:15PM and back down until park close by 2:45PM. A good friend of mine with BVCC said that corporate kept them out of all maintenance and construction, and they are unable to even inquire about anything related to the ride. She has been involved with every new project and ride refurbishment aside from this and no one in her office can figure out why they were not part of a single thing from start to finish.
