It's the function that matters, not size.

If you ever thought that those massive ships move through the narrowest canals and crowded harbors on their own, then you're wrong. In fact, giant ships are tugged by tugboats, as the name suggests, that are 1,000 times smaller than them; and that reminds us of what exactly "function matters, not the size" means again.
Tugboats, which can generate up to 3,400 horsepower, also help with other vessels that cannot move or are disabled, and unable to complete their route. Thanks to their system of rudders and nozzles, tugboats are extremely agile; they can get to the crime scene fast when a fire breaks out at sea, for example.
What's more, if a ship is too massive for just one tugboat to handle, others can chip in and they can work together in teams to move the ship through a canal or a port. That's not all we've got to tell you about these little guys; watch the video above to find out more about them!
