Re: Tug Boats
Tug Boats are the Beast. They pack huge power in small size.Normally they have towing power of minimum 40T to 120T.
The credit actually goes to water. Water hardly provides any opposite force for Tugs to push or pull big ships.
Even a small 20T Tug can easily tow a standard panamax. only thing is that it will happen at very slow pace. The Tugs have one job, they have to churn enough water to create thrust which can displace or move ship. Remember, anchored ships are easily moved by sea waves, Tugs are way more powerful than that.
When a ship is anchored, normally it moves in circle because of the waves, instead of staying put at one place.
All the Tug has to do is break the inertia of the vessel and start the movement. Once this starts, it's an easy job from there.

Re: Tug Boats
It's momentum and the support of the water, Pesta. It takes the engine to get it going and then it's plain sailing!Another example. Those strongmen pulling a plane or a huge truck. True, they are muscular guys, but after the effort put in the start the pulling, the actual moving the object is much lesser an effort. I've done it myself with admittedly a smaller vehicle.
Look at ants carrying leaves fifty times bigger than they are.
Good thread actually - how many examples can people think of?
Go on Realist, give us the physics......

I have to say it's baffled me for years

Good reply too Floydy... I see that now, get the motion and it's plain sailing .. thanks sunshine
Gosh, I feel thick. I'm ashamed - I like to think I'm so logical and I obviously ain't
