What's really crazy is how fast you can pass out and subsequently die entering these spaces without the propper equipment or degassing procedures. In the Navy we are taught not to enter even just to try and pull someone out because of previous incidents where rescuers become casualties and multiple people parish. That's really wild though that metal oxidizing is the reason I never knew that but it makes sense.

This is just the tip of the iceberg in terms of anchoring in general. A real good overview of anchoring for large ships. Smaller boats use different types of anchors and anchoring systems. Fascinating and oh so important for sailors who are not marina hopping and need to be safe over night. Small boats use a variety of anchor styles to dig in below the surface of the bottom using the weight of the ground above the anchor to help hold. Anchor chain, where used, is used to hold the anchor flat on the bottom so it digs in not up. It can take a long time for an anchor to burrow and develop full holding power.

@@koharaisevo3666 The holding power compared to the weight of the ship is amazing but the forces needed to keep the ship in place are not related to the weight of the ship. My 33 lbs. anchor with 40' of chain and as much nylon rope as I need for the conditions (chain and or rope used for anchoring is called the rode) will hold my nearly 13,000 lbs. boat but I'm really holding against the forces of wind on the hull and rig, wave action, and maybe a tidal stream as well. The forces might only be hundreds to a thousand or so pounds, maybe just a tenth of the weight but still much more than the weight of the anchor and chain. The anchor will hold the boat bow on to the dominant force, wind or current so the forces are less, less wind or water force on the pointy bit. If an anchor had to hold the ship sideways the force would be so much more.

What happens when you start dragging anchor, let out more chain?

On smaller craft, I found it advisable when weather demands to take heed of foul weather/ winds/seas/ tides is to secure a heavyweight to the chain about halfway down so it will shorten the anchor scope. This will keep the anchor digging, instead of pulling up. It saved me a couple times. Good for crowded anchorages.

It literally took all day of dropping the anchor, going back and forth to try and pull the anchor in different directions and hauling it back in.

There genuinely felt like no good option that didn't present a significant danger to either the ship or the torch operator.

How about lifting the anchor as far as possible, with the entangled chain above the waterline, tying a very thick rope to the old chain and to a bollard on the ship, and dropping the anchor again? Otherwise, taking the anchor up almost as far as possible, tying a rope to the chain before the winch, taking the anchor up a little (tensioning the rope), and then cutting the chain between the winch and the rope? That section of chain should be nearly free of tension. Finally, drop the anchor with the winch; you lose the anchor, but at least you can move somewhere else. Would that work? That stuff is so heavy it's almost impossible to do anything...

Show a very full array of anchors. I just found this channel. As a former cruiser, I think new people will love and benefit from it. I can't remember the English anchor name I settled on, but it was amazing. When I demonstrated it upon selling my boat, everyone loved it like myself.

On a ship as long and relatively narrow as a battleship it really isn't. The short moment arm (think small lever) means that it would have to have a ridiculous amount of force on the chain to spin the ship. The rudder works because it is at the end of the ship pushing sideways (long lever from middle with the force at a right angle), whereas the anchor is at the front side of the ship pulling backwards (also technically a long lever, but the direction of force is nearly in line with the lever, so the moment arm (the distance of the lever perpendicular to the force) ends up being short). Well, okay, it could work if the ship was already moving sideways somehow, but battleships have keels to prevent that. So a cruise ship with it's omni directional engines might pull it off. Or well, actually... A battleship can totally do a handbrake turn! It does one every time it anchors in a wind or current. The wind/current pushes it sideways and the anchor chain pulls it to point upwind/current. So yeah, they do them all the time! They just have to be moving sideways from an external force.

Also, if you wish to turn the ship in a very tight circle for example, trying to berth a ship with a following tide, we will often drop one anchor and swing around it, so we can approach the berth while stemming the tide for greater control and safety. The ship has to be doing less than a couple of knots for this to be done safely though. Once again, great vid.

'Bitter end' had its origins when rope was used on the anchor, before chain was commonly available (17th and 18th centuries). When the anchor went up and down, the rope at the ship end often never got used, and was always at the bottom of the pile (no automatic washers back then). When the stinky, fetid, anchor cable came aboard, it dripped and oozed down to the bottom of the pile (in the cable tier or cable locker) and that end became 'bitter'. There's also a theory that the inboard end was attached to the ship by being wrapped around the 'bitts', or cleats as we sometimes call them. This would make it the 'bitt-er end'.

Great video. I used to run an oil tanker fleet from a desk in London and had absolutely no idea how a ships anchor worked. Indeed, I never actually saw a tanker in real life but would order them all over the planet just the same.

I never knew I'd like to know that. But I did so much, I actually rewound several times to try and remember the terminology! Now for some reason I feel like I've learned sth that'll come n handy somehow some day. Thank you very much!

Great video! So clear and concise! I appreciate how you also covered how the anchor chain is stored in the ship and why there is always a lot of water flowing out of the ship after raising the anchor. All makes so much sense. I had suggested this video a few months ago! Many thanks, sir!

Thank you for bringing out the nitty gritty of our profession so smoothly and precisely.

Well done. Very good explanation of how an anchor and chain work together. Very accurate.

The chain will dampen the shock when it is lifted and will also have some friction on the ground. However, once all the chain is following the catenary line, the horizontal force on the anchor will equal the horizontal force on the ship. At this point it is only the anchor that holds the ship.

@mytech6779

This. I found the animation good but the narration full of bad information. I would also add that while large ships just use all heavy chain, smaller boats will often used lighter tackle and add weights at specific distances to get a better holding-power to weight ratio out of the bottom gear because they may not be using motorized anchor equipment and have less issues with shock loading because of less vessel mass for a given surface area. Also: different anchor designs for different bottom types, and some anchors have a second line on the other end in case the flukes get stuck under a rock or similar object it can be pulled back the other way. The second line is just a rope and much shorter(attached to a small buoy) also handy if the main line breaks or the bitter end wasn't secured.

@MatthijsvanDuin

Agreed, though even when lifted from the seabed the weight of chain still plays a critical role in ensuring the anchor can perform its task by minimizing the vertical component of the force on the anchor

@JohnPaul-my6ct

The ship can "anchor" without an anchor just using the chain. We have done this just running the chain out with a large buoy and towed by a boat. We did this where the bottom was just rock. So no anchor no hold on the ship?

@@JohnPaul-my6ct Rusty's statement had an important conditional: _once all the chain is following the catenary_ ... the scenario you're describing requires that a sufficient amount of chain is actually _resting_ on the seabed (and therefore not following a catenary), and that section of the chain effectively becomes an anchor (albeit one that is purely friction-based)

@JohnPaul-my6ct

@@MatthijsvanDuin So how does the catenary curve form, from anchor to hawse pipe? The cable from hawse pipe to sea floor acts as a spring because of its weight, the friction with the sea floor by the remaining cable keeps the whole assembly in position. The anchor keeps the cable in position if there is a large force on the ship. If the force is such that the cable leaves the sea floor to form a catenary from hawse to anchor you are in bad trouble! Especially if your engines aren't immediately available! The Naval handbook sets out cable lengths to allow for enough friction to be available under all circumstances, anchors are not needed. Its the same as towing a vessel the spring is provided by the weight of water on the tow rope it MUST remain submerged if it comes out of the water it will probably snap causing alarm and despondency to all concerned.

Great Vid 😉😎

Hello there from the central of procrastination. Still need to do a good amount of math homework but this is the answer to a question that I had for years. And so more important. Thank you for making that video.

Found this channel today and I've binge watched, literally every video. I'm from Southampton, UK so I always see huge cruise and container ships, glad to now know a little more about them! Appreciate the good content, I've been on KZread for 12 years, I can tell you've put in a lot of work into these videos, hope the channel continues to grow.

Me: Why is this guy making a video about how anchors work? It's obvious how an anchor works. I've seen good topics on this channel before, so, I'll watch for the hell of it. Me 6:04 later: I had NO idea how how an anchor works, and I bet 90% of people don't either. NICE! Since we're on the topic of anchors, I've seen videos of ships losing their anchors, could we get a break down of what's happening? Why the anchor isn't connected to anything at the bitter end, is it a failure of the chain brake or negligent operation of the chain brake, do they bother to recover the lost anchor and chain, how much chain does a typical ocean going vessel carry, if they do decide to recover the anchor and chain, what would a recovery operation entail, how would they "feed" the anchor chain back into the ship, etc. Great video. Thanks for taking the time to make it. I never thought I'd be so interested in anchors.

Every single one of your videos, and I mean literally every single one, has taught me something I would never have imagined about ships. I watch a *lot* of educational KZread, and you're easily in my top 5 niche channels. This seems so obvious to me now, given my knowledge of math and physics, but I had no idea of it and would never have guessed it if asked. That scene in Battleship felt very wrong, but in my mind I figured that the maneuver would break they anchor. I will never, ever have an opportunity to make use of this information, but for some reason I still feel very grateful for it. Well done.

Great to learn some new stuff! I always thought it was the anchor and the chain just "helped," along with stronger chains for heavier anchors. On a side note, for the yachting industry, they actually paint their chains different colors at the different lengths, instead of just having the shackle to go by. I'm glad to hear you'll be trying for a monthly upload, especially since February is next! :)

I yesterday had a discussion with a friend about this topic and the scene in Battleship. Now I can send him this.

My father told me a story about when he was in the Navy on the USS Mississippi and they dropped the anchor too early going into an Anchorage. Needless to say the anchor caught the bottom played out and the chain broke. Luckily the chain broke outside the ship or it would have been really dangerous .

This was surprisingly informative,never thought that the chains had this important role.

I used to work on cruise ships for 10 years but they made me take a break and go through Anchor Management before I can return 😎

It’s the funniest thing! I was JUST wondering about this the other day, and now here’s a video answering my exact question! Thank you!

I think that the anchor is more important for holding power than is implied in this video. I say this because ive spent most of my adult life working on anchor handling tugs and i handled plenty of anchors that were attached to their vessel by steel wire rope, or cable, ie laybarge. I also see plenty of wire in semisub mooring systems, i even installed nylon rope into semi sub mooring systems, as well as buoys into systems to keep them off the bottom.

I was also thinking the same thing... otherwise why would you bother with the anchor in the first place? Secondly his explanation of how an anchor needs a sticky bottom to bite, not solid rock, goes against his belif that the chain does all the work. Thirdly if its under heavy force and it picks up the chain does the anchor just pop out? He said they need to power up to the anchor while removing the chain untill they are directly above it... shouldnt they just be able to just pull the anchor up with out powering up to the anchor in the first place if the chain is doing "all the work"?

Great explanations. I will practice this on my 25ft Bay boat. Thank you.

Excellent explanation. This does not only apply to a ship! We ha e a 34’ sail boat. Exactly the same process with one exception. We only have 40’ of chain then a nylon rope called a “rode” in this way we can reduce the weight and less the stretch nylon rode to act similar to a chain. I have seen many small boats with only “rode” and no chain this will never work because the rope would stretch out and pull UP!

If you’re doing a “handbrake anchor turn”, you’re not steaming straight ahead, you’re already turning. Which means that any force exerted by the anchor chain would indeed have a vector component that would help to turn the boat (as well as a fairly major component that slows you down). You’d definitely have to abandon the anchor chain when you’re done turning though, and I’m not rewatching that terrible movie to find out if they did.
