How does a canal lock lift a boat uphill without taking it out of the water? Follow one boat through the gates as the chamber fills, levels out, and drains again.

This original 3D animation shows a common gravity-fed canal lock. The boat stays afloat while the water level around it changes. The filling and draining passages are enlarged and exposed so you can see the flow; timing and operating details are simplified. This is an explanation, not a guide to operating a real lock.
