Wow thanks everybody for the nice words! I didn't expect this video to explode so much.
Thanks everybody for all the views and comments!! If you wanna support the channel I just opened a patreon! my idea is to share ideas and talk about the future of the channel with all of you
This AI narrator is pretty good tbh.
The method you used was good mate. A clear & easy to understand voice at a natural pace, with simple diagrams & clear text. The information your telling is the most important thing. No electronic sounding voices or over-bearing music which add nothing. Enjoy what you do & once again thank you my friend + I wish you the best of luck! UK.
don't ever use AI for any reason
would like to hear human voice with pure emotion
@Yogesh_chavan17same. Creates a more human connection
5:15 "real measuring dimensions"
Woah shots fired 😂
They gave us a weight in blue whales though, so it evens out. Although, I don't know the conversion factor of Blue Whales to Cheeseburgers.
@BHouse65 961,538 cheeseburgers
And they go back to feet immediately when talking about the shackles. It’s hilarious.
@BHouse65 Cheeseburgers is a little broad. BUT 526,315 Big Macs is about the same weight as 1 blue whale. Honestly, I thought it would be more.
Most of the video is in metric, so they obviously aren't using real measurements.
Turns out anchors do work the way i thought
Nerd
They’re pretty self explanatory if you actually look at them so it does not make you a nerd, but you are so kind
@no_one5259 They work the way I thought too. Although, me taking physics is probably a contributor to that haha.
@no_one5259 tf u mean “nerd”, doesn’t take a genius to know how an anchor works
@no_one5259 bro u prolly a dumb ahh kid discovering basic physics 😂
2:50 I hate it when people uses blue whale to make weight reference... I have never carried a whale 😂😂😂
Americans will use anything except for the metric system
@oxymoron458 way to generalize, syfm
Well that's you. Those of us who carry blue whales for a living understand completely.
@oxymoron458🤣🤣🤣🤣
thats something like..... 170 something toyota corollas bit more bit not enough to hit the 180 mark (sedan version)
That's exactly what I would have said if I was ChatGPT
Chatgpt would spew hollywood nonsense based on data from movie recaps and screenplays
Indeed. How is noone else noticing this???
1:41 "the anchor will dig in much easily"
@herzogsbuick So grip.
>"Anchors don't work the way you think"
>looks inside
>works the way i think
Damn pirates listening in to youtube when they should be sailing!
LIES
Damn presumptuous title that assumes every viewer is a moron, whereas in reality only most of us are. Second only to presumptuous titles that assume the information is of critical importance. "What you really need to know about dental floss" Third only to fake wow-factor. "You'll be amazed and won't believe what happens when you put an egg in boiling water!"
😂😂 I said this to my wife.
Like. I absolutely do understand how anchors work Ive been sailing nearly all my life however now I gotta watch to make sure lol.
@Nailedit-p7q Want to get a full understanding of how anchors work and can drag? Own a 40' cruiser and anchor off in the strong current of the St. Clair or Detroit river with hundreds of other boats for the firework shows. You had better know your stuff before you slam into another person's million dollar boat. I put out over 100' of chain and rope to make sure that I am locked in.
The AI voice in this sounds like Patrick Bateman describing his morning routine 😂
That's what I thought too!!! LOLOL
It does! That's hilarious and all I can see now
Let's see Paul Allen's anchor.
😂😂
The AI writing is the real genius part. And what's really brilliant is that it's written by AI.
02:00 and because I was up at 3 am last week, I know how the chain is made.
Seems like I'm the only one who's learnt from this video! I didn't know that the chain is the primary weight of anchoring. It makes sense but I didn't know until I watched this video. So thanks
Yeah, maybe we are the only ones stupid here
Same
same
I didn't know. I avoid being on a boat for I am a land lover.
Same like the chain being laid flat on the seabed so that the more the ship moves the more weight is lifted off the floor to oppose the movement was totally new to me?
You need to actually check your AI slop script.
Otherwise it's full of small but errors. Start with the Blue whales size.
100%, had to pause the vid to look it up. Yup, off by nearly double.
Yeah I was pretty sure they were more like 100 tons not 250
Also 90ft of chain isn't a "shackle", its a "shot" its funny to watch this video as someone who used to manufacture anchors and chains for the USCG and Navy
@justalocal110A 90ft length of chain is called a shackle or a shot, with "shackle" being the common term used in British and international maritime circles, and "shot" more frequently used in American English. Both terms refer to a standard length of anchor chain, which is 15 fathoms or 90 feet (27.5 meters).
@sakikogookhengsilly American me assuming our unit of measurement is universal 😂 I did not know that, thanks for educating me.
160kg is not heavier than a grand piano. A baby grand weighs 227-272 kg. Concert grand pianos weigh 408-544 kg.
I thought so.
This is why AI content is shit
😂 Does it matter? You spit inside of plate of food just because one small tiny portion of it was salty?
And a blue whale isn't 250 000 kg.
@itslike123 it matters because the new generations will be idiots.
Write your own script
is this not his own script?
@authecity no its made by a machine that predicts the next words based on the words of thousands of dead people
@NoNameIdk1what?
@melissagangu580IT’S CALLED CHATGPT
1:39
This is the most ChatGPT-flavored script I've ever heard.
These kinds of scripts will flood youtube in the coming years if it has not yet
It's not just (blank) it's (blank)
It’s insane how much traffic these videos get
i thought it was a really really good video. i don't think chatgpt can do it that well, at least not all by itself.
@towmetothemoondo you wanna blank? Or blankedy blank?
As a maritime captain for 30 years it turns out these anchors work exactly how I thought they did.
I would be worried if as a marine captain for 30 years you didn't know how anchors work...😅
@aqurate-yt You'd actually be surprised. Especially the guys who got licensed before 1995. In the old days, all you had to do to become a Marine Captain on some vessels. Was to just have a letter of recommendation from someone else with a Captains license. There's still a few of these guys around. They're the ones you see on the news crashing into bridges and such.
@thecurbdog123 damn.... the more you know...
@Saihamaru ffs, don't believe everything you read on the internet
@thecurbdog123 what changed in 1995?
"In real measuring dimensions". Subscribed!
Did exactly the same! 😂😂😂
Hell yeah ! Imperial measurements are thrash
Metric is based
as an american engineer, i approve this message.
They obviously subscribe to commie units instead of FREEDOM UNITS! 🤣🤣🤣
That was needlessly savage loll
1:21 anchor magically levitates and avoids getting caught on the rock edge.
as a harbor pilot with 20 years of experience I have probably anchored around 1000 ships, an anchor will definitely stop a ship if it's going pretty slow. We use anchors to help ships turn when going slow and no tugs available. Bouncing an anchor off the bottom at slowish speeds can aid in handling.
One of the coolest things I ever got to see when I was in the Navy over 40 years ago (other than running over a Russian sub of course), was dropping anchor free fall *from* an Aircraft Carrier. The speed of that chain ripping up through the locker was awesome to say the least! And the noise! 🤯
I did not immediately understand your comment correctly...it took about three seconds to realize that the air craft carrier was dropping anchor...
As I read your comment, I was picturing your ship suspended above and dropping an anchor onto the TOP of an air craft carrier.
In my head, I was thinking "was his ship flying, or was the aircraft carrier below the surface?" I finally figured it out!
@missellyssaExactly. I thought the same. Thanks for helping me understand it
@missellyssa...😂😂😂 After rereading it myself I have to agree so I changed it.
@davidonyenwuba4236...Oops! 😂
Free fall from an Aircraft Carrier? Didn't know they could fly...
2:05 A grand piano weights between 225kg and 530kg. Even the lightest grand piano weights more than a single chain link.
Thank you! I was about to post this
I thought that comparison seemed wrong. I was thinking, "well no, I can't bench 160, but I can definitely lift or budge it a little and I'm pretty sure I can't budge a grand piano without wheels, so that seems wrong..."
Except Linus’s piano
I’m questioning the aquracy of this channel…
Thank you! 🎉❤
4:23 i drive
Yes
Real human bean
im literally him
iPhone… 🤙🏽
i hate that i laughed at that
Side note: grand pianos are significantly heavier than that, unless you've been ripped off... but at 5:13 this is exactly the correct way to contrast the metric & imperial systems.
Agreed, a grand piano is 300-500 kg
Side side note: a note dropped inside a piano survives, but o the ocean, it gets wet.
And a blue whale weighs less than 230k kilos. Really seems he pulled the comparisons out of thin air.
5:39 "three means the third"
Let him cook
Isn't painting the links a simple digital encoding as opposed to analog?
@bobhuang94 still analog, just because it's discrete doesn't make it digital
@whataboutthis10I'm being pedantic, but digital data and signals existed long before computers. The abacus is a digital calculator. Smoke signals and Morse code are digital means of communication. However, the common use of the term digital usually implies computers and binary data.
Ok
A grand piano weights much more than 160kg.
Just like a whale ain’t 240 tons
Just the comment I was looking for! I heard that and I thought… whaaaaat?
@JOthatsallrecorded blue whales did weigh about 200 tons, average adults weigh around 150t. so one might think there are ones out there that do reach a bigger size and a heavier weight .. in whales measurements I guess 200k kg or 240k kg, it's about there
But a Grand Piano on a diet doesn't.
@weldmaghrebyou are right but it’s still just a guess and 40tons is a lot but yea the sea is so unknown it might exist
6:07 Lol, that scene from the Battleship movie 😂
Dude you forgot pirates of carribean, dead men tell no tales where jack sparrow did this!
@abhinav788They've already done it in the previous movies.
@abhinav788 tbf, i feel a wooden ship may be more capable, but still unlikely. But a big ass metal battleship? Absurd.😂
@jaywilm89 They literally drift it on the ocean lol
What a great content. Great 3D modeling really appreciate the work that goes into it 👍👍
Thanks!!
Hate that this is AI and doesn't come right out and say that.
Who cares?
@myname-mz3loI do
This is a good use of it
Because they don’t need to. It doesn’t affect you in any way. Grow the fuck up
Haters; hate
For people unfamiliar with the metric system, a kilogram is about the weight of 100 rounds of .308 Winchester and a meter is about the length of a Louisville Slugger.
You're welcome.
o/
Tee hee!! Another merica joke, boy do these never get old 😂😂😂 so funny
I'll stick with the more accurate measurements of:
- About the size of a loaf of bread
- The length of a football field
- Half the size of Rhode Island
Also, 1km is equal to around 5000 bottles of Head & Shoulders Classic Clean Shampoo 400ml (which is around 24,41 square inches) aligned end-to-end
@madslick4147 I use squid beaks myself.
0:12 middle of the ocean ! really?
?
@Styphoryte ships don't anchor in the middle of the ocean. It's too deep.
😂Anchored in the middle of the Pacific Ocean with 10,984 meters of chain (plus the extra length due to the curve, of course)
@elephant35e
He meant slightly in the middle of a ocean
Dont take it exact middle of the ocean
@elephant35e
Lack of common sense
Excelent vídeo, thanks!.
2:25 average car, proceeds to show us a bunch of Porsches, taycans or Panameras or smth
which is doubly ironic because he's saying "average car" to give a weight comparison, but not only is a taycan not an average car because it's an expensive luxury sports sedan, it's also electric which means it's way heavier than an average car lol
No matter what you americans call them MBs, BMWs, Audis and Porsches are normal cars in europe. They're literally everywhere.
Luxury? 17 year olds get BMW or Audi as their first car.
@UltraCasualPenguin The most common car models in Europe vary by year, with the Dacia Sandero and Renault Clio being top contenders in recent years, while the Tesla Model Y and Volkswagen Golf also have high sales figures. SUVs as a vehicle type are currently the most popular segment.
And he tells us 23 tons is the weight of 15 average cars, which means 1,5 t by car, but the Porsche Taycan weighs 2,3 tons...
@asmoth360 1400 to 1800 kilograms is pretty accurate weight for a regular sedan/hatchback or even wagon/suv kinda car.
“In real measuring dimensions” 😂 EXACTLY!
1:40 "much easily" dumb AI
Sort of sounds like a script reader who didn't proof read or say "much more easily". If it's AI, it's as smart as it's prompts.
You beat me to it! I was like, "What?!"
@mattmarzula*its
I see what you mean. The "it's prompts" part, right?
It's is It is. Its is akin to his/her.
@mattmarzula proofread*
Ingenious ! 😀. Thanx for sharing ☘ ☘ ☘
Excuse me mister, a grand piano is not lighter than 160 kg
Thank youu!!!!!
OMG Im glad you spoke up! All this false information everywhere suck!
Having moved a grand piano I can attest to the accuracy of this comment
Without looking it up I would say a grand piano has to weigh 2,000-3,000 pounds?
looked it up
The weight of a grand piano varies significantly with size, ranging from about 500-600 pounds (220-270 kg) for a baby grand to 900-1,400 pounds (400-635 kg) for a concert grand.
If that is true, why do they dont use grand pianos instead of anchors?
I imagined the unimagineable force 6:34
i spit out my coffee 😂
@dandymcgeeI can well imagine. ☕️🌬️
Anchored off the canary islands, La Gomera, our windlass malfunctioned, the anchor roller bow sprit (made of quarter inch welded aluminum) bent about 45 degrees over to the left, almost letting the chain slide off the roller and in to the siderails
Two of us of the three man crew had to haul up 60ft of chain by hand in 10-20kt gusts, cap on the helm... took about 4 hours because every time the wind ripped down this hill on to us, the boat pushed back and the anchor chain tensioned, pulling it from our grip like butter. by the time we got it up we had discovered it must have been buried deep in silt or wedged between rocks on the seafloor, the 25-30kt gusts we had the night before sure dug it deep.
For anyone wondering, we were not able to get the windlass repaired for about two weeks and had to hand haul every time. Busted my foot the same week dropping a Danforth on it, sailing is not for the weak-able or minded🤣
Thank you for this story. It was really interesting❤
yes
I’m just amazed that the aluminum deformed that much and didn’t snap off.
My experience has been if you put that much deflection in an aluminum piece (especially if it’s been welded as you are going to have a very brittle bit adjacent to a very soft segment of metal) you are going to have a catastrophic failure and end up with one piece now being two.
I would have loved to had a clip of that happening, preferably high speed photography. Seeing metal fail because of extreme stress is almost hypnotic.
@just9911Oh i have a picture of it, it was the first thing I did before approaching it further, i can't imagine how much force was going through it, the skipper reckoned it was somewhere between 800-1000 pounds of force but who knows! We actually had an albatross hit our mast on passage a few nights before we arrived there, I learned they can be a bad omen 😂
I hope your foot healed ok. and still functional except for weather prediction.
Was this written by ChatGPT
I am a pro pianist. There are no acoustic grand pianos that weigh only 160 kg or 352 lbs. They weight 500-1200 lbs, depending on what size grand:)
Can you imagine if they made an anchor chain of grand pianos??
Thank you i knew that was way off, and if 1 thing is that off there are probably others. Waste to watch.
Im a professional mover and that weight bugged me too lol
Blue whales don’t weigh 230,000kg either
How much would 500-1200lbs be in real measuring units?
@5:58 Isn't everything "physics-driven reality"? :D
It's an ai script, can't expect too much😂
Ships cannot be anchored “in the middle of the ocean.” The middle of the ocean is way too deep. Ships can only anchor near shore.
I was pretty sure someone else would catch that stupid remark.
that was cool! :) and informative 👌
Big chains don't break. Your windlass brakes will fail first, then the last "resort pin" breaks, hopefully before collapsing the chain locker wall. It's meant for discarding a chain that you simply can't recover so it's way weaker than the chain itself. As a safety officer I loved stenciling "Bitter End" next to the big hammer. One time that chain wall was bent in almost an entire foot. We had to replace the pins with something weaker. Still, saved the company a lot of money, but the fitter wasn't pleased to work for a week in the locker.
I've seen two big chains break. They do.
I had on a few occasions the ship I worked on literally break free in Maui. Snapping lines on ships of this size is terrifying, I'd hate to see what the anchor could do to it.
@poa2.0surface77 Come on, you know the answer, Ford v Dodge ensured the answer forever.
@poa2.0surface77 No, the fact that the pin didn't break meant that we didn't have to fish out the entire anchor and chain, or get a new one. I was just a cadet at the time.
@BigGuy42080 I guess it depends on the definition of "big", relative to the size of the ship itself. On my biggest bulk carrier they didn't seem "big" anymore, we didn't trust them that much. Even so, the chain is not supposed to break first, other things are designed to give way. If the chain snags on the rocks and it has corrosion, some manufacturing error, or they're really old, sure. But that's a rare case indeed. Thunder did strike twice for you.
6:45 I love the anchor scene in "Battleship". Its impossible on SO MANY levels. Not only could the chain not withstand the force, the anchor couldnt either nor the sea bed could itself. And if both those things somehow magically worked, the idea that a ship that long can do a handbrake turn while pushing enough water to float a battleship out of the way instantly? The anchor is only a couple yards off the centerline, it would be like having a 700' long teeter-totter with a car on one end and you pushing down on the other with your hands, but the fulcrum is only 5' from YOUR end so the car has massive leverage over _you_ .
Yeah, that movie was incredibly ridiculous. I don't know why I like it, I usually hate movies that are that dumb, but I do.
It was a fun movie, filled with impossible stuff as it was 😂
It was followed by the best firing sequence ever. Pure cinema back when movies could be made for the fuck ya value
I never feel that fun should be scientifically correct . Learning part of brain is not engaged while watching or doing fun things !
@lunchbox1398
Speak for yourself! I feel so very sorry, for you, if you don't find learning to be incredibly fun! For me, I am _unable_ to remember what I learn unless I _enjoyed_ learning it.
"the anchor will dig in much easily" -> Ai
How do you know? I am not a native english speaker.
Is this a common AIgen sentence formulation?
Bravo this was very well done!
Well done video. When I was a submarine officer, we had the opportunity to use our anchor many times (this is unusual for submarines), so we got to understand it quite well, and we were always trained that "it's the chain that holds the ship, not just the anchor."
One minor note (since you are [correctly] criticizing other representations of anchoring, it seems like being accurate is important): At 4:47 when the anchor is being retrieved the animation shows the flukes turning backwards (pointing straight down). I don't believe this is how most anchors are designed - the flukes can only rotate with respect to the shank by a limited amount (+/- 45-60 degrees?) - this limited range of motion is even shown at 1:12 in the video. This limited rotation is what allows the anchor shank to be used as a "lever to break the flukes free from the seabed" as stated in the narration.
Overall I loved the video (although, I will admit that Beethoven's 5th Symphony as an underscore seemed a bit mismatched to the content, IMHO), and I've subscribed!
Thank you and keep up the great work!
A memory just came to me. Are there anchors that actually do dig in? For a very specific use, a kind of hightech spearhead that burrows?
I distinctly remember seeing one in an article as a kid. It was cool, but ridiculously over engineered iirc. Could've just been a concept though.
@VikingTeddythere are various types of plow anchors, which are meant to dig deep.
I thought that part didn't make sense. If the anchor is fluke is free spinning then there couldn't possibly be a lever
@GigaJiggYup. There are actually many different anchor designs, this video covered one specific design, but really was focusing on the function of the anchor chain as part of the system and the general procedure for deploying/recovering, so I didn't quibble with that choice.
@SamuelGeist I didn't run those numbers specifically since the anchor chains I'm used to working with were never as large as the ones they were describing, but I would agree that 150kg (~330lbs) is too light for a grand piano (or even a small upright piano).
4:02 "secret sauce" this was written by ai, nice video though!
Not only written but also narrated, still learned something though
@GetRoasted1Honestly I don't even mind if someone writes their own script and uses AI narration, some people have annoying voices or thick accents that make them hard to listen to. But the AI writing is what I can't stand. It's always so bad and obvious.
Pretty sure it's botted views too. Channel only has 14k subscribers with over a million views
@GetRoasted1 even if it’s ai I still learned something from this 😅
Secret sauce is a pretty common phrase, no?
0:10 no anchor has ever stopped a ship "in the middle of the ocean"😅
Give it credit the ai slop is definitely improving 😂
Why not?
There's no reason it can't.
You're probably assuming that the middle of the ocean is always incredibly deep.
And there's no ⚓ chain long enough to reach the bottom anyway 😂
Very interesting, thanks for the educational video!
Many comments saying anchors worked exactly as they thought it did.
I'll be the simpleton and admit I actually learned something from this. Namely, I had no idea anchors could do that thing at 1:11. Thought they were one massive solid piece. Thanks, video! :)
Some probably are a single piece.I bet for smaller ships or boats there are different anchor shapes, and I'm willing to bet in smaller boats the anchor is heavier than the chain. He's using a specific situation with a gigantic ship only to support the title of his video.
Crazy how many people have never been around simple boat
2:25 "average cars". Yes a last gen Porsche is definitely average :D
He meant avg weight of a car
That’s what I also thought haha
@gmshivansso9940you don't know what he meant.
An anchor is completely useless in the middle of the ocean.
yes. the chain isn't like 3km long
Ships don’t anchor in the middle of the ocean.
@matthewbyrd398 on those cases the ships stay in place by constantly using their thrusters or by using what is called a 'sea anchor' (a parachute like device)
Well, it depends on the depth of course. Some areas in the middle of the ocean are not necessarily especially deep so an anchor may sometimes work satisfactorily but a sea anchor will help restrict the amount of drift if you can't use the normal anchor.
Why would a ship even need to stop in the middle of the ocean anyway?
Masterful presentation! 👏👏👏
I don't know how accurate the info was, but the presentation was great.
Right?! Who even cares about the truth at this point?
@sean_fisher i love our modern dystopia! i don't have to think or anything~
@lunafoxfireyeah, it's the ideal situation really.
Great visuals! Was just explaining to my wife the other day that essentially, the anchor holds the chain, and the chain holds the ship! Also, in the US Navy, the scope of chain you let out is typically 5 to 7 times the depth of the water to make sure you properly set the anchor and have sufficient chain to not drag. For one difference between commercial vs US Navy, the first detachable link (connecting the first shot of chain to the second) is red (with one white link on the either side), the second detachable link is white (with two white links on either side), the third detachable link is blue (with three white links on either side), and it repeats red, white, and blue with the appropriate number of white links on either side to give you an idea of how many shots of chain you've let out! Thanks for the video!
Agreed! In your video, the ratio between depth and chain length seems to be around 2. As an amateur skipper, the recommended ratio should be 5, under heavy conditions 7.
Freedom chains
Beside the wrong piano weight, the biggest blue whales are 150 - 180 tonnes. Most weigh less than that
Bro really over romanticized anchors
He's a good teacher when something so stupid is somehow so interesting 🤔 was really enjoyable
It was likely written by AI. They tend to be quite flowery and over descriptive.
@RezDiscipleimagine being so butthurt over AI that you can't even enjoy a video without being triggered
So what
He got me.
Amazing explanation.. never knew this.. thanks for sharing
01:40 "much easily"?!
*more easily* if you please
It was jarring AF
came here to say this
It will dig in much easilier
Much easier or much more easily😁
Fantastic info. Super easy to understand.
@3:38. The same shock absorber principle applies when you are towing an ocean going barge. When you're using a 130' ocean-going Tugboat pushing a 500 ft barge, once you get out of port and head out to sea, you drop out of the Notch and you go on the Tow. When the correct amount of cable is let out, it's completely underwater. All you see is a short length of it going up to the barge. All that cable underwater acts as a shock absorber between the barge and the tug and the waves and the current. Ex-navy, Merchant Marine engineer.
That's pretty neat. I wish I had followed my dreams and become a mariner, I always thought that would be a cool career.
6:11 should have used the Pirates of the Caribbean song there. 😅
And lose ad money?
Enjoyed this, but the AI narration was a bit much
Clear English too much for you?
Where's your video? Post it up please.
Your mother never said too much
"You will be shocked by this game changer"😂
@tomarmadiyer2698awe anime nerd mad nobody buys his drawings anymore? Boo hoo!😂
Such a fascinating story. Thanks!
2:37 a fully grown blue whale weights 243,000 Kg? WOW
It's not more than 15000kg a whale!
Largest one ever recorded as per the Guinness Book of World Records - 190 Tonne (190,000kg)
@dipinthewalkernot so bad of an approximation
google says 130-150 tons.
@stevejones5753😂
Yeah dude... Like the longest ever recorded d*ck was 13.5 inches in America.. (googled it)
One can definitely make a not so bad approximation of an Average Adult American Male ____ size.. I guess!!
"real measuring units" like blue whales and average car?
Interesting. I used to pull underground fiber optic lines, and even after a few hundred feet, the drag of this lightweight fiber line get considerably heavy. For longer lines we'd need guys to lift and pull to the main puller isn't yanking all the weight. The kind of lines we used to pull didn't like to be twisted or kinked, so we would have to fully uncoil it on the ground before pulling it into a conduit.
wow, great animation!
More please!
I 100% learned something about this, so many answers and even follow up questions! I mean did they really use that technique with the first very boats? hinge on the anchor idk if I’ve ever seen that, especially not on an old boat?!
No way you think a grand piano weighs only 160kg. Was this whole script written by ChatGPT or something?!
yes, the most obvious tell imo is when it says "its not just x, its y" and so on. pretty sure i heard it multiple times in this video, but there are other tells like grouping in odd numbers etc
In mythbusters they tried to turn a car by shooting a hook to a post or something, and it snapped every single time. now multiply that force by like a million.
awesome experience and graphics
A grand piano weighs about 600kg. More than 160kg of a single link of a medium size anchor chain at 2:10. Even an aircraft carrier or super tanker anchor chain tops out at 230kg. WAY less than a grand piano.
This video showed me that anchors work the way I thought they did.
you think you fully grasp the mathematics behind the hyperbolic cosine catenary curve? 😂 maybe you do i could be wrong but for some reason i highly doubt it lol
5:20 90 feet of chain is a shot
Ok
What a fantastic graphics video and everything explained very clear! Thank you very much.
damn.. US feet measurement catching strays for no reason. 😭
😂
Always a reason to shit on foot fetishists
It's a British measurement...we just let you borrow it 🤣
But yeah, I know what you mean, metres make my Braincell hurt
The very existence of those measurements in the 21st century is reason enough already 😅
can't afford freedom metrics in this Trump economy
2:06 no grand piano weighs less than 160 kg.. they average between 260 and 500 kg apparently...
Yeah, he would have been better off giving the weight in 'Elephants (African)'
Apparently
yeah that doesn't sound right at all. one of those links for sure isn't 2 of me, i've seen them up close. probably more closer to 1600kg.
I think it is worth noting that the chain 'thing' really only applies for massive ships in the ocean.
However, if you are anchoring a smaller boats (especially in more shallow freshwater "bodies"), the anchors do just work by "digging" into the floor/bottom. They ALSO 'similarly' rely on their mass - but the "digging" crucial in windy conditions since the mass is insufficient on its own to keep the boat in place. For these smaller boats, many times, the anchors are attached ONLY with rope, but many do have short chains (a few feet) at the base/end of the anchor line. This applies to Jon boats, wakeboard/wakesurf/ski boats, pontoons, house boats, cruisers/"yachts", and other "smaller boats" (though, these "small boats" can be 50+ft in length - which is actually fairly big IMO).
That said, SOME smaller anchors rely SOLELY on their mass (no digging) to hold boats in place - though this really is only used for VERY small boats like jetskis, and they will often fail in windy situations. These "mass-only" anchors won't even have spikes/hooks/points/etc. - they will be "rounded off" and often are shaped like an upside-down mushroom. These are used because they are very compact, so you don't need to store them in a tiny boat.
But for the "digging"/hooked anchors, there are MANY situations where the chain (and its mass) is negligible/nonexistent, and the boat's anchoring relies almost entirely on the "digging". This is why these smaller boats will use an "anchor rope length" that is MUCH longer than the water depth. In particularly windy conditions, many people/boaters will use an anchor length that is 7× the depth. This is because the "angle" (between the anchor-line and the lake's floor/bottom) needs to be smaller - which allows the anchor to "catch" faster & "dig" further into the ground.
Point being, this 'chain mass" 'mechanism' (described in the video) really only applies for VERY big SHIPS in deep ocean waters that have those VERY long, VERY heavy chains.
I have a fairly big IMO, too!
Not enough to become a porn star, though.
We ALREADY KNOW that every comment with citations or quantitative analysis is MERELY an opinion, , so don't bother being timidly redundant.
IMO going now.
For another point going in that direction: a cargo ship weighing 200,000 tons can afford to carry 200 tons of anchor + chain, it would be another story on a 2 tons leisure ship.
@briseboy
I should have added a comma for more clarity & readability - though this wouldn't be grammatically [or logically] necessary to properly read & understand the sentence.
The current phrasing/formatting could be considered 'ambiguous' w.r.t. the 'flow' when "reading the sentence [aloud] in real-time". However, when you read it 'silently' & 'backtrack' if the 'flow'/emphasis/interpretstion results in illogical English - then there is no logical ambiguity in being able to read+understand the sentence (i.e., there is only one manner in which you can interpret given the sentence's context).
However, adding a comma (to 'fix' the psuedo-ambiguous phrasing you pointed out) would go against the 'spirit' of [the rest of] your reply -- it would be redunant punctuation. Your comment expresses 'disapproval of redundancy' while simultaneously requiring redundant punctuation to 'fix' the clunky phrasing. This is a bit contradictory, no?
Also, the use of "IMO" is not any more redundant than fixing the phrasing. That sentence was phrased as a declarative factual statement - and "IMO" serves to indicate that I am NOT making a claim of factuality. Additionally, an opinion of 'size' (whether something should be considered 'big' or 'small') has large variation from person to person. "IMO" would only be considered "truly redundant" IF I said something like 'I think [xyz] is big IMO" -- because saying "I think" indicates a statement of opinion rather than a factual declaration.
After removing "IMO", the sentence would still be logically/gramatically correct, but it would require context to ensure the reader's proper interpretation/understanding. Just like how my current (clunky) phrasing of that sentencd requires context to ensure proper interpretation (otherwise we end up with the "fairly big IMO" reading). That is precisely WHY I included the "IMO": to eliminate the need for context.
Either way, you were entirely "aware"/intentional when you removed the sentence's context to 'poke fun' of the phrasing - which is a pretty blatant misinterpretation of the logical consistency of my sentence. Ultimately, your reply has an inherent contradiction on this matter. You can't simultanously 'disapprove' of [even minor] redundancy while simultaneously 'disapproving' of the minimally-redundant "logical interfacing" of the grammar in that same sentence. "Fixing" the phrasing of that sentence requires introducing redundancy into the comment.
Very good explanation. Thankyou
I knew all this already. I spent about an hour one day on the Intrepid talking to a vet about his job in the forepeak.
There's one big error in this video--the form of the links. Anchor chain links are shaped like a Greek letter Theta, the oval with a line across the middle. Without that middle part, the chains illustrated in this video are susceptible to kinking. The middle part of each link is necessary to keep the chain from kinking.
This is what you get if AI makes a whole video for you. Hopefully there will be an AI blocker, just like ad blockers.
I saw that straight away--still its good as an explanatory tool.
There is a way bigger error in the video.
Take a closer look at the ancor.
Not all mooring chains have a central pillar
@AvangerCellar, would you be so kind to tell us, please? I didn't find it.
But, but, this is exactly how I thought they worked. Which therefore means, this actually isn't how they work at all.
f*** you got me there...
NOTaBOT-mf8 Wrong.
@lolzlolz69 Who are you, Joshus's BF?
lol
@TheChzoronzon Haven’t you got some homework to be getting on with?
I'm pretty sure I'm old enough to be your father, Mr "LOLZLOLZ"
:D
You aren't very good at this, are you?
The anchor does not work without a chain?
Big shocker, thank sfor going through all the trouble, making all these animations to reveal such a crazy revelation to us mere mortals.
🤡
I feel like the video provided a bit more info beyond the chain connecting the anchor to the boat…
you think you fully grasp the mathematics behind the hyperbolic cosine catenary curve? 😂 maybe you do i could be wrong but for some reason i highly doubt it lol
Simple, visual, straight to the point, tightly packed, informative.
Bro says anchors don't work the way you think, then spends 6 minutes 57 seconds explaining that actually they work exactly how everyone thinks.
ah ah ah so true!
Yep, they work exactly the way I thought. Chat GPT isn't the answer.
you think you fully grasp the mathematics behind the hyperbolic cosine catenary curve? 😂 maybe you do i could be wrong but for some reason i highly doubt it lol
@ashtonsanborn9006you can barely type, of course you have a hard time believing it. 😅
@ashtonsanborn9006 the video doesn't talk about it either anyway
If you ever flew a kite high enough you probably know how heavy a simple string gets when tugging that kite
Super interesting content. Keep going! You're on to something!
6:35 I don't want to imagine that force
Good thing he said it is unimaginable
I disagree with your last statement though! I spent 20 years in the Navy as a deck ape. An anchor "chain" is actually called a cable. A cable link is extremely tough. If too much pressure was actually applied between the ship and a stuck anchor, the cable would fail at the deck clench at the bottom of the cable locker. That is the weakest point in the entire system. If the Blake slip is engaged, or if the weight is middled between the gypsy brake and the Blake, it might absorb the shock. It's rare cable links fail.
When all this fails, the deck clench is coming up through the naval pipe! Get out of the way, you are about to have a bad day...
Weak relatively. There was a recent case of sabotage where a ship dropped its anchor and dragged it for >100 miles, at full speed for a good portion. Internet cable lines were severed.
@queenlip6152It depends how the anchor are held. In the case of when an anchor is no longer "home" this should be verified during every watch. Even if there is sabotage, there would definitely be sings the anchor is dragging. The cable would be having a peculiar motion and would be slapping up and down against the decks and bulkheads for example. The noise would be significant.
I cannot speak for civilian fleets, but in the Navy, ships are continuously inspected at least every 4 hours. The Petty Officer for our trade would do continuous rounds every hour around all deck spaces. Problems are normally found within an hour of occurring. On most ships a dragging anchor and cable would be felt.
Only two ways to sabotage an anchor and cable, and they all have to be done manually. I reviewed my old notes after my original comment. It's actually the bitter end that is the weak link. The bitter end is connected to the deck clench. They usually follow together when the anchor and cable runaway.
The ship I was on once had a runaway anchor because the gypsy brake failed. All 10 shackles came out of the cable locker. In that case there wasn't full momentum and the bitter end and deck clench held. It's a hell of an unnerving thing to witness though.
@msamourI was very curious about this anchor dragging business. The “What’s going on with shipping” channel had some good videos about the anchor dragging sabotage. I’d be curious to hear your take on it. It makes sense that everybody on board would know what’s going on
@dannyovryn4120I am not aware about the other channel. One thing is certain, everyone working on the upper decks would be aware if an anchor was dragging.
In addition, the officer of the watch has to take a fix for the log every so often (some ships it's every 15 minutes at anchor) to ensure the ship is not dragging her anchor. Normally, the Captain is informed as soon as it's determined the ship is dragging her anchor. Corrective measures are then normally taken immediately.
Fantastic and informative video, with great animations! Love the "In real measuring dimensions" at 5:20 :)
Very nice animation! Also great explanation how it works.
Thanks for putting that weight into perspective with something none of us have actually seen.
2:10 Only if it is a toy piano. A vertical piano weighs on average 500lbs, and a concert grand in the vicinity of 1000lbs. All significantly heavier than each of those links
5:19 Not dimensions, but units. The dimension stays the same: length.
The video is really fascinating🥰🥰
2:07 ehhhh that doesn’t sound right. Maybe I’m wrong tho
Loved this video. All the people who haven't been on ships can learn a lot from this. As for people who are mariners, 'Pls stop crying that you already knew'. This ain't for you.
All modern commercial ships have chain counting sensors that are integrated with the ships monitoring software. Shackle markers are still painted for redundancy and they’re also mandated by regulations, but not really used anymore.
Forgive me, I am an old school mariner, as in sextant not GPS and I learned the 90 foot measurement of chain was called a SHOT and not a SHACKLE! When did this change? Does anyone know IF this has really changed and when. Shot is the same terminology on both sides of the Atlantic!
0:22 the driver in shifts in the midle of the sea?
