Why are they called Tugs when all they do is push?

Try going between this TUG and the barge behind him and you see why they are called Tugs. :lol:

Early tug boats were used to get larger vessels in and out of confined spaces so they pulled as much as the pushed. The first boat specifically designed to be a tug (about 1800) was the Charlotte Dundas, a paddle wheeler . It was supposed to replace horses for pulling barges on a canal in Scotland.

As I get older I find I've become a source of totally useless information. But I know a little about early steam powered ships from reading the history one of my childhood heros, Isambard Kingdom Brunel. A great name for one of the world's greatest engineers - among many other accomplishments he designed the first "modern" ie., iron, propellor-driven ship. Now on display in my home town of Bristol, England and well worth a visit if you are in the vicinity.

We look out over Elliott Bay and watch tugs constantly. It's about 50/50 - half of them are towing, and the other half are pushing, nudging, and otherwise guiding stuff across the water. One thing for sure, especially from the perspective of those of us avoiding their wakes and swells, 100% of them PUSH a lot of water.
This video is a bit long (8:07), but if you jump to about 6:30 you'll see the Class B and the Unlimited Class tug races from 2011. That's some displacement!
