Thanks for that post BTB - I actually recall seeing a documentary about the Falkirk Wheel on TV. What an awesome sight and amazing engineering achievement!! You Brits must be proud!
Jeff, the cost of taking the Big Chute is the same as any other lock on the system. On the Trent-Severn system, they charge about $1 per foot for each lock, or you can buy weekly or seasonal passes for all locks. Its a pretty cool ride, and yes, all passengers stay on the boat as its lifted out and transported up or down a 60 ft incline. The huge dolley is run by pulleys and can fit about four or five 20-25 footers each trip (more or less if boats are bigger or smaller...)
I've been on dozens of times, and each trip is still a thrill. Cameras are always clicking, so I'll search for a few pics to post.
Just to show our British friends that they're not the only ones with a cool lift lock, here is a video of one of two lftlocks that we also have on the Trent Severn system, This one is near Peterborough, Ontario:
