Crossing the Panama Canal takes most of a day. An outside lecturer comes on board the ship to explain the process as it is happening. The sketches below will help you understand how it works. There are 3 sets of locks and 2 lanes of ship traffic. Each set of locks features a control house on the center wall. The vessels are assisted in their movement by electric locomotives which use cables to align and tow the ships. The largest size ship that the locks can accomodate is 965 feet long and 106 feet wide. The link at the bottom of the page will take you to our photos.
