Every year, about 14,600 ships pass through the Panama Canal, one of the most important waterways on Earth as it brings the United States closer to both Europe and Asia by connecting the Pacific Ocean to the Atlantic. The canal works through a complex system involving tugboats.

When a ship wants to enter the canal, it approaches the waterway from the sea. At this point, several tugboats attach a towline to the incoming ship and move it into alignment with the canal locks’ narrow entrance. Once a cargo ship is firmly within a lock, a tugboat stays behind to make sure it does not displace itself. 

Then, the lock gate behind it closes while the gate ahead gradually opens. This causes water to displace, raising the ship so it can then enter the next lock, where it will eventually join Gatun Lake.
