Career
He is particularly noted for his work on designing and relocating several major wooden roller coasters in the 1970s and 1980s. A number of these coasters were world-record holders at the time of their opening. On the subject of roller coaster design, Cobb has been quoted as saying "You have to be a little bit mean.
Sometimes you have to be a little bit sneaky.
You get them going on a nice straight track and they think "This looks smooth," and then you dip it down a little to give them a good jolt. Or you have it so that when they go over a hill it looks like they"re going to get their heads chopped off at the bottom".
The following roller coasters were either designed or engineered (in whole or part) by William Cobb: "If you make it too smooth, it"ll be like sitting in your living room.".
