I'm more amazed by the cable they using to pull those massive ship
I use to amaze by elevator rope
Now I working in elevator construction
Now it's feel normal

To quote Tugs, "The tugboat, for its size, is the most powerful craft afloat."
I’m here because of that show, TBH
So it is basically Thug boat !
😂underrated

The tugboat, for its size, is the most powerful craft afloat. And the tugs are the power behind the docks and waterways that make up the a Big City Port.
I saw it pushing around a nimitz class carrier, it's quite a sight how a small boat can push that behemoth around.
On tugboats you want thrust.
Thrust: This is created with surface of the prop. Surface is created with diameter and the size of the blades.
Pitch: The angle of the prop on the shaft which creates the theoretical movement forward with one rotation of the prop.
Slip/Efficiency: The difference between the theoretical and practical movement forward with one rotation of the prop. Less pitch is less slip and by that more efficient.
The power of a prop is a combination of surface and pitch. If you have a lot of surface you can't combine this with a lot of pitch of the blades because of the limited power of your engine.
So the conclusion:
1. A tugboat uses large props with a little pitch and low RPM what creates a lot of thrust with minimal slip but not so much speed.
2. A speedboat will use small props with a lot of pitch and high RPM what gives a lot of slip before the speedboat will reach higher speeds, the prop will be more efficient at higher speed.
Edit:
This is without talking about cavitation or ventilation. Which are very important things and can also give a lot of trouble.
Second edit:
Nobody asked. I just hated that when you talk about tugs you don't talk about the most important part which is the prop.
Huge explanation
Aww man. My EKG test was LAST week!
Mann, that's the best explanation
I was wondering why tug boats with all that power and relatively not much weight are not fast and speedy, thanks for that’s explanation!
What is “Pitch”
This is why diesel engines are the torque monsters in the car world, construction diggers and even at sea. High torque at low rpm is the goal here.
"Become a tug boat. Move shit that's 1000 times physically larger than you" - grizillionaire mindset
Well you know what they say
The tugboat, for its size, is the most powerful craft afloat.
And the Star Tugs are the power behind the docks and waterways that make up the Bigg City Port.
This…is _TUGS:_

The tugboat, for its size, is the most powerful craft to float
I was watching this tug boat pull like a kilometre long log train through the river
The captain knows the river and currents/back eddies like the back of thier hand.
Did the river have any bridges to navigate?
@Laura Brown shut up
Tugboats are floating engines.
Tug boat are the true king of sea
Wow i learnedsomething new today, Thanks!
Tug-boats are the little big heros of the seas.
Damn I'm feeling really down
Tug boat: don't worry I am always here if you need help
Thank you Mr. Tugboat!
LoL, I'm here because I remember my childhood shows, Tugs and also theodore tugboat. lmao xD
designated spots where it's safe for tugboats to push - an example of info I came to learn. Thank you.
It also helps that they're built with just enough boat to float the biggest engine they can fit.
“The tugboat, for its size is the most powerful craft afloat. Captain Star and his tugs are the power behind the docks and waterways that make up Bigg City Port, This is tugs!”
I love seeing the Svitzer tugs push huge oil and LNG tankers in the harbour near where I live
Of course, tugboats are already quite powerful, as they use either medium size boat diesel engines, or even actual train (locomotive) diesel engines, to provide crapload of torque to the propellers (propeller design matters a lot too), just so they can push themselves through the water HARD, in order to be able to pull large ships out. Not to mention they have to use rather strong ropes to be able to tow without snapping. Extra horsepower and torque also make them much more versatile than just to tow, especially when fighting fires, as water would be under so much pressure which is necessary to be able to reach much further than the typical firefighter hoses if they have to fight fire from afar, to name a few reasons why strong engines make them more useful.

Things you will not find on a tug boat, a prop, a train engine, and “ropes”
Dear tug boats, thank you for your service
Well, That was one of the Most Interesting Thing I was Interested but Couldn't Get better answers from anywhere
The tugboats don't move the vessel, they help the vessels move.
Not always true, I see tugs push big container ships sideways into the slips at the Savannah port all the time
Finally ... one of the biggest mystery to my mind has now been answered 🤣🤣
Very interesting😁
Good video.
what did shipping do before these amazing tugs??
You should rather present them from the underwater view ;)
Thanks
Tugboats can stop a cargo ship from hitting bridges.
Small ship but with big power
In term of moving, is it generating high rpm on basic propeller or generating high power to rotate such powerfull propeller with lower rpm?
Thanx
Question is:
Can it pull an Aircraft Carrier?
probably yes but they need like maybe 3 or 4 tugboats
Yes.
Aircraft Carriers are tiny compared to 15,000+ TEU Container Ships, not to mention Crude Oil Tankers and Coal/Ore Bulkers.
If dom drives it as in FF5 VAULT STYLE
Come here because my 4 year old daughter asked how the tugboat can tow the big ship in one of Richard Scarry’s book. She has learned from experience that any questions you have can be plugged into UA-cam search and 💥 answers!
So cute
Nice
2:25 that’s crescent fleet a tow company from New Orleans
so your telling me ONE tug boat could of saved lifes during the baltimore bridge "accident".. why does everyone half ass their job ?
what's the maximum velocity of a tugboat when it's running by itself? (not pushing or pulling another bigger vessel)
7-16k^ depending on engine and throttle.
@maharlikan958
Not at all. Max speed depends upon the hull shape.
I miss being in a tugboat when i was a cadet
UNSUNG HEROES
Tugboats are hero we need, but dont deserve...
I really want to become a tag operator, how do I become one, what is the process?😊
Same phenomenon is used at airports...
Imagine a tugboat(fishingboat right the actual name? Isn't tugboat the long length and short height? Or small and short length?) small and standard of "all country's choice before appearing as 'country of'", I think of tuna fishing, 1 pulley system in middle as the fishing wire, to just fish 1 and keep selling, I wonder how much is the rental if install that to leave it hanging and then sell? Solo life of fishing? Or how much is such boat?
Question: tugboats can also perform rescue operations in open sea?
In a rescue operations at open sea all vessels who are near are obligated by tradition and international law to help and attend the call, with just some exceptions. Having said that, most of the rescue operations are performed by tug boats, only that the design are different with much different capabilities. Most of them with D.P system.
@@alfonsodiaz434 really interesting. Thanks for the answer, I really appreciate it.
1 question - does traction matter in water like in range rover in land?
Yes

Thrust: This is created with surface of the prop. Surface is created with diameter and the size of the blades.
Pitch: The angle of the prop on the shaft which creates the theoretical movement forward with one rotation of the prop.

If you are going to post a video, first be sure that you are accurate on the subject!
Its called momentum
I mean take a look at Suez Canal. Takes an army of tugboat to push the darn ship from blocking the canal....
One day in the future a Trillionaire will have a private super Yacht the size of a container ship. You watch!
I want to own a tug boat
Up to THREE propellers acting in TANDEM? LOLWUT?
Methinks "Interesting Engineering" doesn't understand what the word TANDEM means.
You guys really need to get a different voice over artist
Evenrude in it lol'
"interesting engineering"... Erm no more like "stating the obvious and clickbait titles"
amateur design diesel boats. Now imagine a Tugboat with a a CF-6
Thug boats are amazeing!!
I use dyneema. But I'm the best tug in the world, pushed into port? Your welcome.
Diesel Tugs: Amateurs! None of you have the strongest steam tug in this harbor.
Hercules: ua-cam.com/video/nX3hpMonZW4/v-deo.html
Diesel Tugs: ?!
Hercules: I beg to differ, old boys! *Brings in a cargo ship* My name is Hercules. And I am the strongest and largest Star Tug.
Giving a force in tonnes, a weightunit
Just. No.
Ok
Makes me a fun… Idk imagine… cuz…. Its like.. the ship is on started… or sail.. its jsut the little tiny boats 😂😂😂😂
An engineering marvel.
IMAGINE A TUGBOAT THE SIZE OF A CRUISE SHIP
That means they need very powerful engine, which may or may not be achievable using standard tugboat engine. Bigger hull means more displacement and friction, there will be a point where efficiency of a tugboat is not better than the ship it is supposed to be towing. Maneuverability must be taken into account too, the purpose of the tugboat is to help maneuver large vessels. I doubt tugboat of the size of cruise ship will help in a place it is supposed to be operating from.
Still not big enough to tug deez nutz.
I can handle a bollard pull of up to a few pounds
My question is who is the one dislike and why
Vessels won't grow bigger, in fact they even became somewhat smaller last 10-15 years.
Ok, explain why the latest container ships are still getting bigger. They are now at 400 meter length.
@@nielsdebakker3283 yeah they have been 400×60 for a while now, they only managed to carry more TEU because they make the vessels more block shaped and they use their space more efficiently. You can't make a ship bigger then the port it sails to. The LOA and BOA won't change anymore.
The average tugboat Engine is nothing compared to the huge wartsila 2 stroke rt flex wich produces like 108000hp.
No, but they have much more powerful engines than other boats of a comparable size.
Every engines have their own power and strength
Your wartsila 108000 hp engine will become useless when it comes to the port at that time this NOTHING tug boat engines only help for you so don't underestimate any machines nothing is bigger and smaller
why are subtitles in the video? if users want them, there is an option built into the player.
I will very bad luck
nya
I've come to really dislike this cliche way of presenting a video with a typical deep voice and predictable sentences like TV used to be
Plzzzzzz sir i request to you
(Make video on business field)
Plzzz sir 🙏🥺
Interesting "Engineering"
@@iNomNomNomYou00 ok sorry
Tug life N*gga
How long are the stuides to become a thugboat driver
It varies depending on what path you take. The company I work for you can have the accumulated sea time in a couple years to sit for the exam. Then you'll begin training.

Most of the information here is inaccurate.
What a stupid title.. its not hard to understand 😡😡😡😡😡 how can ppl not know this 😡😡😡😡😡
What? Not everyone knows about boats and ships, it's an educational video, your ignorance is astounding!
@@supahfly_uk BLABLABLA…
Ppl dont know about LifeBoats to Cruise ships.. even if they do, they dont speak nice to / about Them 😡😡
