Tug boats work in teams thats were all the movement comes from other wise A single tug boat has between 700 hp - 3000 hp
thats were it is strong thats like 300 times more hp than a lamborghini and it has a lot of torque

In the water there is much less resistance than on land. Once movement has started it is easy to keep the momentum and dierect it. The number of tugs will be determined by the weather conditions working against the movement of the ship. Things like wind and water currents. Without those factors it is easy to keep a ship moving with a comparably smaller tug boat. The times when more tugs are needed are when there needs to be more manuverability (or working against weather). Using tugs in the right places make it possible to turn the ship without making a several mile loop. Some ships are equipped with bow thrusters. Those are basically a built-in propeller in the front of the ship that can move the front of the ship from side to side. The bow-thrusters aren't made for a lot of power and are often substituted with tugs.

Massively strong engine. As mentioned above, 3,000 to 25,000 HP whereas a 28 foot recreational boat will have 330hp.
Extremely huge propellers. Like over 10 feet in diameter. Whereas most recreational boats have a 2 foot diameter prop.
A comparison would be in motorcycles. A 750cc Honda CB750 engine produces 68 hp, whereas a 600cc Honda CBR600 engine produces 120 hp.
BTW, some tugs aren't little, at 50 to 80 feet long. But tugs in general are just a floating engine.

The answer is yes. Tugboats do many tasks when "attaching" to a target vehicle. Many times, tugs actually push on a boat to turn it and thus, the tires on the bow. The big thing about a tug is the power to weight ratio that allows the tug to move much larger boats in the water. There may be quite a few needed to move around the target boat. Consider "spinning" a boat. One tug aft starboard and one port bow. Start pushing and the target boat will spin in place. So don't think that a tug can simply "tug" as they don't. Towing is a very small part of their job.

Not as technical as the other answers, but It's what you dont see from above.
Asked same question while walking around a boat repair yard & saw a "small" tug out of the water.
I was amazed by what was below the waterline.
A deep hull for the massive engines & huge propellers.
Answer i got & what everyone else said, it's all about power, power & more power.
Best regards

Above are good answers.
Tugboats remind me of the children's story about the little train that could. They may be small, but, they have a big heart.
I have building plans for a small 24 foot tug. It will have less than 100 HP. She may not pull a big ship, but, I bet she will have the heart to push it around some. :-p

You wouldn't call a tug boat small if you looked at the propellors. There huge and the engine is very big too. The propellors move a lot of water!

Strangely enough, tug boats are actually pushing the big ships!!
