This isn’t new news, but it is crazy news. From calorielab.com:
In the original Anaheim Disneyland it may be a Small World after all, but that world’s inhabitants are getting bigger and heavier almost by the day, so much so that some of the rides may have to be re-engineered. The problem, quite simply, is that the flume that the boats ride in, and the boats themselves, were designed and built in 1963 on the assumption that the male adult riders would average 175 pounds and the women about 135, which they pretty much did at the time. The ride now must accommodate adults who frequently weigh north of 200 pounds, which it often cannot do. Increasingly, overweighted boats get to certain points in the ride and bottom out, becoming stuck in the flume.
