Been in the harbor tug industry for 24 years now. Our towing Hawser, is a thicker heavier line used for towing something larger than an average sized ship. We rarely use it these days as the strength of your regular working line on the bow and stern winches are able to handle increased loads. Great video! Very accurate with most of the information!
Hawser line? What is the typical diameter of the line and what is the strength versus a normal line? I’m sure the cost is hugely higher than the regular lines.
Me, too. Then again, some tugs are used only in the harbour, so only in a "personal burden emergency" would they be far from a toilet. Reminds me of the late Duke of Edinburgh, as he was getting older, who said "never miss the chance to go to the toilet"
Hi, i am an ASD tug master. Very interesting and accurate video but I have to point out some inaccuracy in the video. Tugboat shown in the video is an ASD tug. In Harbor operation those kind of tugs NEVER operate by the stern winch as they can capsize as you mentioned. They are designed primarily to operate by the forward winch both for safety and maneuverability. Towing by the stern winch is only used when long towing is carried out in open sea. The tug in the video should have a bollard pull of around 70 Tons and they will never use it to tow a 300+ m Ship in open sea. For such big vessel an AHT with a minimum 200 Tons bollard pull is required for open sea towing. Last but not least, ASD tugboats are Best allround harbour tug as they carry all kind of operation efficiently.
@@OneNiftyBoi Tugs really only has to be heavy, small, powerful and with propellers suited to high thrust at low speeds. All this infers a displacement hull shape, but the reasoning is incomplete. A planing shape might still made to work, but there's no point.
@@OneNiftyBoi The tug has the weird underwater shape to let tons of water access the propellers. Without that shape a tug might sink itself because all water under the stern of the tug is removed.
Great video! I worked on tugboats, but a long time ago, when I was young. Then my life was spent on huge container ships. Now I am 60 years old and I dream of returning to tugboats again. In the story about tugs, I would also add that tugs, including port tugs, are equipped with a fire extinguishing system that is capable of extinguishing fires on large ships. I once saw such a fire in the roadstead of the port of Busan.
That was something I noticed as well. I have never seen even the smallest tugboat to not have at least one monitor (thats what the usually but not necessarily remote operated movable water nozzles for firefighting are called). Also I would have wished to see an explanation about another very common propulsion system with tug boats, the Voith-Schneider Propeller that allows the same rate of propulsion in every direction and can smoothly change direction immediately. It looks like rudders on a spinning plate, where the angle of attack for the propeller blades can be shifted in relation to the position on the circular plate (somewhat like the pitch on a helicopter rotor). Although while a VSP is more effective and can react quicker to changes in steering direction, modern Azimuth thrusters (in combination with Kort nozzles) are simply a lot cheaper to build. By the way, in larger applications you may find Diesel electric propulsion instead of a z-drive, where the Diesel engines run a generator and the Pods house an electric motor. But I guess that will mostly be found from a certain size. It sure is how Azipods on modern Cruiseships are build, but those are way bigger. Oh and one Minor flaw on the rendering of the containers on board the ship, both MSC and Evergreen, and I don´t know who else would sure prefer their containers to be not stored upside down ;) The lettering on the containers is upside down.
Tugs have always fascinated me, thanks for providing a glimpse into how they work so efficiently for their size. Keep up the great work, the narration was brilliant.
Great video. This is a very impressive and important boat. The agility and power of the boat is insane. I was supprised at how much power a boat like that can have, I knew they were powerful but having 20k HP is something else hahaha

It was 1981, my ship, the USS Inchon LPH-12, boiler backfired at the Norfolk pier on our way to Gitmo.. I was in 2nd division at the time and I was volunteered to go TAD aboard a sea going tug. It was a USS Something. Anyways, the 3 day tow from Norfolk to the Philly shipyard made me realize manual labor sucks, 6 years later I earned an Associate Degree in Laser Electro Optics. I lament I got that degree 40 years too soon.
This is fabulous. Thank you for such good visuals and explaination.I have been riveted to the Dali story since the bridge disaster ( May 2024) and have been in awe of the tugboats and even the vessels with the cranes... how they maneuver so easily. Now I know how. But I would guess that 90 percent is the talent of the pilot.
Holy CAD, batman! I don't even want to think about how long it took to model all this. Beautiful work! Much prefer your human voice over AI, as well. Keep it up!
Thank you so much for your videos, I hope that you make more and more videos about the transportation tools like that with all kind, I can spend time everyday to see your videos.
Thank you Lucius for this highly interesting video. I have often wondered how such a little vessel manages to do the work it does. You explained it so well.
Great video, even if some of the information was completely wrong. eg 1) Displacement hull vs Planing hull. A a tugboat would never get to a speed where a planing hull we be beneficial, b) The thrust (and by design volume of water) would mean a displacement hull would cause issues with lack of support (buoyancy), C) Simple physics in where the centre of mass needs to be. 2) Large tugboat accommodation, You know it's not always a "rescue" some larger tug boats get a multi day towing contract. If the task is going to take more than a couple of hours they will need a place for people to eat / sleep etc. They will also need multiple crew's, atleast multiple coxwains (to man the helm) and mechanics (to operate the engines) if nothing else
Good explanation. You could also have mentioned why the hawser winches are positioned so far forward on the aft deck as their exact position is fundamental as to how the tug operates and steers. 👍
I work in a harbour on a part unrelated to the sailings, but have seen tugs on the dry dock for servicing. I've been always wondering why they have such a deep, bowl-like hull. Turns out it's for adding "grip" in (on?) the water. Thanks for the explanation!
Cool clip ❤ Didn't know much of these Safety rules are written with someone's blood can't imagine how many people had suffered to make such activities safe
I had always wondered hw powerful are these tugboats and this very nicely explained animated cleared all the doubts. God bless u bro🙏May this Channel keep growing and get millions of subscribers. Love frm a tiny dot in the Pacific Ocean. (Fiji Islands)❤.
I knew the captain of the Alexander Towing Company's tug who always kept a full stowage of water for'ead of the bridge, to keep the bow as low as possible. Through the stern port (right in the centre) the towline was winched-down, when needed, to give as much trust as possible - when as a stern tug -- sometimes on a 4 tug towage in dock .
I read a Desmond Bagley book which touched on salvage operations and Lloyd’s Open Form part of insurance. Not sure if true but they used an explosive hawser cutter in case the towed ship sinks threatening to bring the tugboat down with it. These vessels are salvage vessels which are probably bigger than tugboats.
There is a reason why we call them waterways & because of their constantly challenging movements of current, wind, waves & displacement yields we can see the need for a water vessel whose sole purpose is to dig deep on behalf of others in times of want, need, efficiency & safety.
