how can a tiny tug boat push/pull huge tankers and cruise ships?

I get that plane tugs have huge tyres and tonnes of torque, but a boat? A tiny boat? 🤷‍♂️
Thanks

The engines and propellers of those tugboats are comparable in size to those of the huge tankers. The tugboats are smaller not because they have smaller engines but because they do not have any cargo holds or giant fuel tanks. A tugboat is literally just a giant engine and propeller in the smallest boat possible. Not unlike plane tugs.
