You know? Po-tay-toes? Boil ‘em, mash ‘em, block a ship’s deck drain causing a free surface effect introducing instability and a capsizing effect?
Ohhh, interesting. Never heard of them before.
Even you couldn't say no to that!
@@ovzzzz Oh yes we could!! Spoil nice deck drains...
Give them to us freee~ and drrrrainer~ling.
You keep nasty spuds.
I love you.
Also fry them
"What Happened To The Commodore Clipper?" : 13000 views
"that time potatoes almost sank a ship" : *infinite views*
The accuracy is both astonishing and alarming lol
The current title kept making me think that it actually was going to sink so I watched to the very end waiting for it to happen so ¯\_(ツ)_/¯
waiting for half as interesting to steal this video too
Anyone want to buy 23 tons of roast potatoes ?
@@welshpete12 that almost capsized a ship?
*Your GM tells you how stable your ship is*
"Roll a stability check"
"Fak, a 4"
"The hull groaned as the ship capsized, dragging you to dark depths below."
CRIT 1! CRIT 1!
Lol
GM tells you that their cars are CRAP. I trust GM.
Rolling a four versus my sailing skill of fifty six is five success levels, though. I also have the waterman talent so I am immune to stability checks... you're not very good at WHFRP are you, GM? 😐
I had this thought
I work with fishing boats. They have float sensors that automatically turn on the bilge pumps if the water level gets too high. Well, one captain noticed the boat is floating weird and looked in the bilge, and it's completely full of water. It turned out one of those plastic bread loaf clips jammed into the float sensor, and almost sank the whole ship. Those bread clips are now banned from his boat..
The clips they use to close the plastic bag that the bread comes in? That's hilarious in a sad way
But are potatoes now banned on these ships? (Cancel culture!) 😁
@@patrickbuick5459 Only if it's potato bread!
I have had a bilge pump fail from mumerous obstacles, including a cut-off end of a zip tie. Anything small enough to fit through the grating around the pump...
I now have two separate automatic bilge pumps in my boat, mounted at different levels and connected to separate batteries.
I still don't trust them 100%
I used to have one with an electronic level indicator, but that one failed because of some oil in the bilge water.
I have had a mechanical indicator fail because the water level rose so slowly that the float switch didn't trigger until I stepped on to the boat and disturbed it.
If you are in a serious situation where you take on a lot of water, that water is going to wash around inside the hull and find every little piece of hidden trash that was dropped during the last decade and the electric pumps are very likely going to get clogged.
A high-capacity, manual, bellows pump is a really important piece of equipment on any boat that you can't bail out with a bucket.
I could imagine people being confused why that of all things was banned from his boat, until he tells the story.
Can we all appreciate how the crew did a good job analyzing the situation and how well they managed it. They seriously did a fantastic job.
Yup, it could have been a lot worse.
The Commodore Clipper services the Island of Guernsey (where I live) but I never knew that this happened to it
I remember seeing it in the local paper
@@laurencebois5119 you also from this humble little isle?
Unfortunately I'm from Jersey
@@laurencebois5119 unfortunately? You live on the same tiny island as Sips for Christ’s sake, Guernsey doesn’t have a member of the Yogscast.
@@lauran3244 no, we don't have a Nandos
Our Dog is named after this ship because of this incident! My mum and her two sister's were onboard when the fire happened. They we're traveling to England to collect our yorkie pup, hence why he's named Clipper!
Send Clipper my regards
I hope you never feed him Potatoes...
I got a dog called Luna to my home on the Commodore Clipper (When Condor had one) and she is carsick, but was not sick on the way home.
Perfectly balanced, as all ships should be
I'm an aviator, hate boats and open water, but I absolutely love this channel.
So interesting to learn how you guys operate on the seas.
Yea I find being on ships kinda unsettling when we are used to aviation standards, but this is very interesting stuff.
@@Roytulin I just find the ocean scary.
I'm a student glider pilot, we spend a lot of time learning what to do in case stuff goes wrong (obviously) and I'm confident that even if stuff went really bad, I could save myself.
Ocean though? I just hate thinking about stuff going wrong and ending up in the cold, endless, potentially kilometres deep waters, who knows how many NM from any land.
@@Morrov I am in aerospace engineering, and some things on ships make me uneasy. Bulk loading of cargo in flammable containers without partitioning, the presence of self igniting cargo, the lack of a gas based fire extinguishing system, minimal cargo safety inspection, etc. But I suppose I cannot expect all of that because humans do not instinctively fear going into the sea as much as they fear falling from the sky.
@@Roytulin There are ships with all that, but imagine the cost of imported goods if it had to apply to all freight.
There are more planes in the ocean than ships in the air. Just sayin.....
I thought this was going to be a story of how this incident caused the ship to capsize, but the layers of safety and the actions of all involved kept this to only minor damage
Potatoes! We never practiced for the "free-potato effect" in the navy.
Maybe the Royal Navy specify mash to avoid this possibility?
I thought navy sailors occasionally plugged small leaks with potatoes for damage control if they ran out of wooden chalks.
@@ph11p3540 if you are bored enough on a long voyage, there are plenty of holes tp plug... Or so they say...
The free potato effect is not the same as the free surface effect, but instead a possible contributing factor.
@@LuizAlexPhoenix yeah, that's why the navy has the reputation they have.
As an officer cadet I have to say, your videos are really neat.
As it happens, my class is curently doing our advanced firefighting course, and I had not considered the impact mounted fire fighting systems might have on ship stability through sustained use.
definitely something to consider.
The fact that the graphics showed Scania firetrucks so similar to the ones used in UK is a testament to this channel's professionalism and dedication to accuracy. It's a shame youtube is throttling it by screwing with the subscription system
The UK's largely used *Dennis* Fire Engines for most of my lifetime, with DAF (aka; Leyland-DAF), Merc' and Scania making up the rest.
@@jimtaylor294 yes yes, of course you are right. I meant that the Scania in the video looks so much like the Scania fire trucks of British fire services.
On a side note, there is a British charity called Operation Sabre, they bring donated British fire apparatus and equipment to Transylvanian villages. There are a bunch of Dennis trucks now serving with volunteer fire squads in my county, and I always enjoy seeing them
@@tamaslapsanszki8744 Nice :-)
I really liked the animation of gm etc. I used to teach Stability and trim which for many students is extremely complicated. You made it supremely understandable.
Now THIS is USEFUL! It helps to mathematically explain how cruise ships can be so tall, yet not capsize at the slightest wave.
Those monsters rely on active stabilization. Meaning, if they lose power in rough weather, the damned thing goes down. Don't know how that's allowed.
Hitchcock always said that one increases the level of suspense in an audience by *providing* information, not by withholding it, as a mystery or who-done-it usually does. This presentation was an excellent example of the principle.
Once informed of the smoke and the alarms setting upon this poor ship (in the dead of night, no less), we were then slowly informed, not of the plight of the passengers, but of the many things which might reasonably go wrong in such a situation, the whys and wherefores, each of the principles and the inexorable forces involved - and somewhat to my surprise (since I had only expected a mild documentary concerning one or more of the many maritime realities of which I am ignorant) the more tense I found myself becoming.
This was assisted in no small part by the fact that this growing stockpile of disturbing information was delivered by a dry, pleasant but detached voice which seemed vastly more interested in presenting each terrifying detail with perfect clarity than it was in communicating whether or not sixty-some-odd relative strangers would soon awaken to flames, panicked flailing, hopeless realizations and then the frigid waters dragging them mercilessly down to the crushing blackness of Davy Jones' Locker.
Now having experienced it, of course I wouldn't have it any other way.
I won't spoil the experience of anyone who hasn't seen the video yet by revealing the eventual fate of the Commodore Clipper, I'll only thank the video's creator, both for chipping away at my considerable ignorance in an entertaining manner, and for reminding me of Hitchcock's talent and insight. Cheers.
I already knew the outcome wouldn't be too bad because I see the Commodore Clipper all the time as I live in Portsmouth.
If you are wondering, the cause was a cable pug overheating, which caused the fire.
I wish videos were more frequent on this channel
Me too!
probably a TON of work for this high quality!
This ticks the box for 'Learning something new every day'. Thanks!
40+ years in / around the commercial maritime world, in a wide range of roles, and had never heard of potatoes plugging up drains !
Love seeing these videos. Sensible, interesting and your voice is very soothing. I listen to them while I'm working as a jewelry maker. Thanks for your efforts!
Saw the title, thought "what have they done this time"
In the 90s I used to work as a travel agent, and handled a lot of booking for Commodore. They were so unreliable that we refused to sell cancellation insurance.
@@lmlmd2714 nothing much has changed. I used to service their gambling machines as an outside company and we had problems with boarding almost every time.
Irish People: *breathing heavily*
They had far worse potato-related incidents...
Don’t forget the Idaho people
Mouth watering
*MAINE INTENSIFIES*
Didnt have to out me
Been on the clipper many a time... even going on her next week and I've never had a problem, amazing ship!
Beautifully explained about GM. Experienced once a Bad Loading onboard Feeder Container Ship. Somehow somebody authorized additional last minute loading when all actual load was done/signed.
Top heavy.. 20mins departure Ship start to list and did not correct itself. Was saved when the measly securing arrangement broke at welds, n thrown those containers overboard, making the ship righted itself.
We really appreciate your videos man. They’re so watchable and informative. You’ve really struck the balance quite well
I came here for "casual navigation", I ended up with a professional master's degree on navigation.
When I was master of a small passenger vessel, one of the things I pressed onto the crew was to switch the fire system to the bilge system after a few minutes, at the beginning we would pump sea water through the fire system, but then switching to the bilge system to the fire hose we were able to pump the water that had filled us up, to fight the fire, eliminating any more risk of the free surface affect.
Can the cargo decks not implement this idea? Drains at the side with closable valves, pick ups to then send that water around the fire system? You could pump a known volume into the deck initially figiting the fire, then switch over, thus allowing almost unlimited fire fighting that would have a minium affect on stability.
Unfortunately that wouldn't solve the issue.
The drains are perfectly sufficient to avoid this effect by making sure water does not collect on the deck. It matters not if that water goes into the sea or back to the fire fighting system.
The problem stems from these drains being blocked. If the system you talk about was in place, and the drains blocked, the water would take too long to go back into the fire fighting system, essentially leaving you in the same position as if it was going into the sea. Reduce the amount of water fighting fires (and the fire gets worse), or have water collect (and compromise the stability).
That is if I understood what you talked about correctly.
I believe it is a serious design flaw that these drains can get blocked however.
To add on Andres: You also added danger in the system. Worst case is that the fire is a chemical fire - in which case you're just pumping the ignition agent onto everything, while a normal setup will pump it overboard. Even in the best case, a fire creates multiple toxic byproducts which a normal suppression system will dilute, while you're concentrating them for the cleanup crew to deal with.
Connecting pumps to the drains wouldn't be reliable. In addition to the problems pointed out by Andres and Daniel, if the ship heels to one side for whatever reason, the pump on the opposite drain is suddenly pulling air, rather than water. That may damage the pump, and it certainly reduces the amount of firefighting water available.
@@WillowLiv "I believe it is a serious design flaw that these drains can get blocked however." The MAIB report says that the ferry company has now fitted appropriate covers to the drains.
I wish you would have gone into how they future proffered the problem. Seems like this could happen with many types of cargo.
It's always interesting hearing about accidents, but it's nice to see a channel show when things go *right*. Ro-ros have a....dodgy reputation in the UK, but this was very cool to see.
I love the Clipper, having been on her so many times. This story was really fascinating to hear, thank you for this!
I used to like ship,s now i am loving them
Love your work sir
I've sailed to Jersey and back on the Commodore Clipper a couple of times in the years preceding this incident. It's a lovely small ferry. It sails across to Jersey via Guernsey during the day and from Jersey back to Portsmouth overnight, or it did! I think the first time I was on it there were about 10-15 passengers. Nice and quiet.
all sounds and visuals of this video are so SATISFYING
I'm constantly amazed what you may find on RUclips. Thank you for a fascinating story !
Extremely well done and concise synopsis of a complicated situation. Just hopped over to read the official report (memo to self: get a life) and the number of things that went wrong on board and on shore (communications and equipment failures) just goes to show how the smallest thing can be a critical link in the chain to disaster. My fave part of the report was about the harbour tug driver who towed most of the trailers off. Due to the heavy smoke a breathing pack was necessary - he was the only driver with any experience which was scuba diving once while on vacation, and he volunteered. Guy went through numerous tanks of air as he worked - sometimes backing his truck in by feel in zero visibility - and was able to get the trailers, some actively burning, off the vessel. Photos are in the report.
Potato: I've had enough of these potato computer jokes! time for the world to take me seriously!
The potate famine was much more violent than people think
"Ooh, let's sink a boat! Everybody loved that time we took out a Japanese submarine!"
Meh. Irish Nationalists have been overblowing that spud blight famine for generations as a somehow unique tragedy that only effected the Irish; in reality the blight hit all of Eurasia at the time, yet is largely forgotten everywhere else.
The real issue that caused the famine was over-dependence on a single crop; a bit like various countries' history of overdependence on a handful of export products for government revenue.
(Venesuela being a classic case of how an undiversified economy will deteriorate [and people go hungry] at the first sign of a crisis)
Thus it really was a hum drum historical event; caused by agrarian complacency and incompetance.
@@jimtaylor294what I heard is that the amount of land they had at that point (as a result of some well-known events and policies) was not enough to feed them unless they grew only the cheapest and most nutritious crop which was potato
@jetblackjoy There's all kinds of accounts from the period (and quite a few made up / distorted after the fact), but it's worth noting that poor soil fertility was a centuries old issue in Ireland (the island), as Potatoes caught on post-1500's as a result of better crop yields than wheat or other crops.
Side stepping the core issue and spiralling into a monocrop situation (over many generations) was what made the famine inevitable, even without a Eurasia wide blight.
What could / should have been done is a vast topic, but I think it's important that the real lesson of the famine should take primacy in any reading: *Don't Monocrop or neglect your soil, or this will happen (again)*
In contrast; the cause of and takehome lesson of the Dustbowl crisis in the US in the 1900's is well known and understood.
(Hedgerows serve a purpose, nature is a random & cruel mistress, and having a plan for hard times is essential)
Excellent video. Great illustrations and narration.
Wish the photos of potatoes were included!
I've been on ferries many times and always felt nervous about them capsizing with them being so tall above the waterline. The first section of the video made me feel much safer
The reason I don’t ever want to take a cruise on the newer “Mega” ships, way too tall.
I never really thought I'd fine a channel about ships to be interesting, but god damn. I've binged your videos several time now and I still enjoy them.
Your instruction is par excellence. You rendered the explanation of stability and its component forces so clearly in such a precise and concise way that it took my breath away in admiration. You are a very good teacher indeed.
Ohhh I've been waiting a while for a new video! One of the few channels I have got notifications on.
Thanks Adrián. Glad you enjoy the content.
@@CasualNavigation Fantastic video again, as always! Aww, now I have to wait again for the next one. Any hints? :)
There might be a vague link to prohibition...
That was really cool to watch. The hard work in the animation and clear explanation was nice to watch and learning something in how a ship crew deals with these situations 👍
Fascinating! I watched a couple of your other vids, but it's this one that earned you the sub.
Of interest, some warships had bulkheads dividing the ship into port and starboard halves to control flooding and allow port or starboard boiler or engine rooms to remain in action after a hit on the opposite side. Unfortunately they found out the hard way that this assisted the free-surface effect to run rampant on the flooded side, and capsizings following torpedo hits (of a magnitude the ships had not originally been designed to resist) became a regular thing.
This channel is a storehouse of knowledge. Never understood the concepts of center of buoyancy and meta-centre soo well before.
Keep the good work going 👍👍
Damn, an actual happy outcome, I wasn't expecting that. Always happy to hear about scenarios where past lessons learned paid off!
Awesome video as always :) Thanks for also including the report!
I remember my old crusty professor/captain at the maritime academy drilling into us the need to "check your rose boxes regularly" during bilge pump operations. Not sure I've ever heard a bilge drain/pump sump called a "rose box" by anyone else...
Your explanation about gm was so good!
Wow. What a story. So good to hear that they made it to port and could remedy the issue. Hopefully proper drainage systems and incorporated in future builds/modifications will help prevent another close call - as a result of the accident report.
Huge thanks for finally explaining the stability thing clearly
Finally i was waiting for months for a new post i was shook to remember this channel its been so long
Your maritime incident videos are excellent! More of them please 😄
7:28 The driver of that truck must've gotten whiplash due to how fast the turck was moving.
What a brilliant job u do here. Congrats
Please do more videos on maib reports. This is fantastic!
Great video as usual, amazing quality!
This channel deserves millions of subscribers. Brilliant, professionally produced content as always.
This channel is awesome. Thanks for putting effort into these videos
i love your videos, theyre so calming
Absolutely brilliant. Very well made presentation.
Man your sponsor is very cool
Very nice explanation of ship’s stability.
Great video, Really informative as always.
Terrific work! Very compelling and pleasant to watch. I love your delivery! Thank you!
Gotta say, the crew really did an amazing job
Enjoyed that good job CN.
Casual Design did a pretty good job here
Great video as always! A nice happy ending for once, other than the lost potatoes of course.
Amazing content. Thanks for the information
Excellent video mate
I almost came by the GM explanation. BRAVO !
Interesting,I never heard of this ship and what happened to it. I always look forward to seeing you videos (:
Blackadder: What we need is a cunning plan to sink this ship.
Baldrick: I have a plan sir.
Blackadder: Tell me Baldrick, does it involve a po-ta-to?
Or Baldrick's favorite turnip.
I skimmed the linked accident report, and there were a few things that were presumably cut for time:
At first, the crew thought it was a false alarm. The second and third mates had previously served on ships that had had false fire alarms, and so, instead of immediately activating the drencher system, they sent someone to go see if there was actually a fire. Combined with some communication issues, it was about 15 minutes from the fire alarm going off to the crew believing it was actually a fire.
They potentially could have used the drencher system for longer, but they didn't have the tools to quickly determine the maximum allowable list. The report recommended adding equipment to let them figure that out
Because of the structure of a RORO ferry, the passengers couldn't disembark until after the fire was put out. It ended up being okay here, but that's a pretty big design flaw, IMO
Good work.A lesson there for all ship crews.Dont let cargo block the sprinkler system drains.Same could apply to much other hazardous cargo.
As always, awesome video!
Good job by the crew and rescuers nursing the ship into port!
Wow, i can really tell the increase in quality with every video. That being said, i think finally get what the hell the center of buoyancy means.
Do one on the sinking of the “Midnight Hour” a squid fishing vessel that sank of the coast of Catalina Island in California. It capsized I believe because it was over weight. It is now a wonderful scuba diving site!
It’s astounding how much we understand the science behind all of this
These videos are not to best visual quality but it is informateive and i like it.
Yeahhh, didn't thought u be uploading 😊
Love the channel! Could you do a vid on the plimsoll line please?
Really well done
Loved the physics part!
This is such a good channel 🚢👍
The crew did the best they could, looks like they did great, no loss of life!
Wasn't this accident featured on an episode of the TV show "Disasters at Sea" or am I thinking of another accident when the 'free surface effect' played a role?
As constructive criticism: Color coding (in this case) "G", "M", and "B" to match the respective colored arrows could help. However, I can foresee color-coding the letters possibly being hard to read. In addition, maybe say what "VDR" means.
Thank you, Casual Navigation for adding in the description the URL/link to the final report (PDF) of the MAIB investigation as-well-as, the effort and time you put into your videos.
Great video. The only thing you missed was the effect of the width of a compartment on free surface and how longitudinal subdivisions can reduce its impact.
Didn't anyone think about moving the sodding spuds out of the drain ways (see post 10) or were they hoping for Bake tatties. Enjoyed the Physics lesson!!!!!
Looks like the officers and crew did an excellent job.
surprised to see the clipper on here. I've taken this ferry a few times when I was younger to visit family in the UK from my home in Guernsey.
Was happy that no one died! The systems worked - though not perfectly - who would have thought 🥔🥔 potatoes! Would have liked to of heard the suggestions for improvement.
sound effects are really good and funny
A very interesting and informative video
Excellent video
7:40 The scale seems....off....I guess everyone knows doors are the same size as fire trucks lol
It's for big passengers
nice job thank you!
3:00 it's moving up and down side to side like a roller coster 🎵🎵🎵
