Some boat rides can be jerky if the boats back up and bump into eachother like pirates, Frozen, or even Small World. Omnimovers are okay. The ride vehicles are spaced by the track. These include Little mermaid, Haunted mansion, The Land, The Seas with Nemo and friends, People mover, or boats with space like Jungle cruise. It really depends on the amount of “jerky” you can deal with. Barnstormer and Primevil Whirl have “jerkey’ in their design. Check out the ride design. Omnimovers are okay, free floating, maybe not. Ride on a jerky or bumpy track should be avoided.
