Height Limits

[Hyde]

Restraint safety/comfort is the main reason for height restrictions on rides.

If you are too short, you often run into severe head banging and discomfort. This is why B&M, which has some of the most extensive seating and harnesses, also has the tallest height restrictions, particularly their stand-ups and flying.

I know in some of the Vekoma SLC's there is a height limit because the track passes so close to itself at times....Dueling Dragons also had a max height limit, for the same reason, if I recall.

Part are restraints as well. There was no limit on Scream Machine at SF:GA but my friend really was too tall for it. 6'5" and he started coming off the ride in tears, no joke. The restrains dug into him and because of his height his neck was getting thrashed around (opposed to my head for example)
