[@rob28803]

A new design that improves the dynamic response of a ship as it travels through waves? How better to clearly show how _with a series of stills_ .

[@ACD54]

And nothing at all about the underwater shape...

[@bbsaid218]

😂😂

[@butlerproman]

Stills on calm water, no less.

[@chrischristopherh8389]

The company I worked for built six of these, different sizes and they will know better in rough seas than any other design the company was WesternGECO

[@denisoko8494]

It isn't new design, but "forgotten" old one. Similar bow design was wide spread all over Europe. Look at vikings or slavic ships with similar bow about 1000 years ago, yes, it was narrow to fit their raider ships purpose, not so wide like we see for cargo and supply ships in the video above.

[@whiterottenrabbit]

I love how the audible and comprehensive narration explains everything in detail!

[@retiredyeti5555]

Love the sarcasm! I agree wholeheartedly!

[@billbrown7235]

This video is more helpful - kzbin.info/www/bejne/Zn3MnaZ7j95mq6c

[@QueenDaenerysTargaryen]

Yes, very informative

[@almagirimai8931]

would be good to see how this design actually handles heavy seas, etc rather than a series of pretty stills.

[@jerrypadilla4384]

I've seen a video presentation, of these ships, in rough seas.... they do plow through the waves, rather than ride upon them. (Sorry, I cant recall just where I saw it. I think it was in technology group, in FB, I once belonged to)

[@whyno713]

ya know while you're on youtube you can check on the right to see related videos of one maybe in chop, or, heaven forbid, do a search.

[@learemington1700]

I would like to see a video of this design and the traditional bow running side by side in rough sea.

[@OldWhitebelly]

So, we have a design meant to handle heavy seas. Let's make a slideshow of a few of them in still waters and at rest.

[@marks6663]

and put some gay music on top just to annoy the viewer. For some reason, uploaders think a video of photos without sound is unacceptable, so they put some shit on top. So wrong. Just give us the photos. We don't want some music soundtrack.

[@OldWhitebelly]

For that matter, is a slideshow a video? Not in my universe.

[@ronnieg6358]

Yes let's see it in action and if you don't like the music then TURN IT OFF !

[@lorenwilson8128]

My thought exactly - show the bow perform in heavy seas like they said it would.

[@Steve9312028]

I thought the USS Zumwalt was an ugly ship, but this design beats it all to hell!

[@ThePostal67]

That only took 5000 years to update. I like it and always love to see re-inventing anything.

[@zweispurmopped]

Or a thousand years to remember. It reminds of the Drakar boats with their backwards arching bows.

[@denisoko8494]

@@zweispurmopped The similar bow design had slavic raider ships about 1000 years ago, before that the reverse bow design had Bronze era Egyptian and Greeks ships.

[@Subpilot57]

I worked on the Viking Poseidon during the BP oil spill in the Gulf. Spent 3 months on it. Nice Boat.

[@twizz420]

I worked on Vessel Name during 'nam.

[@huntsbychainsaw5986]

That looks like an excellent new design. I've never been on a larg ship before but this design looks more stable and more efficient when compared to what the other vessels look like.

[@mccabe8818]

You can engineer revolutionary ships but can’t have tolerable background music

[@Mikepower1978]

I have been thinking of this for years. On small craft. It makes so much more sense. Old hull shapes were largely determined by timber planking restrictions.

[@bbcala9719]

Nice design. Very interesting, moving control deck to the bow instead of the stern. Very cool tech

[@samiam9059]

Looks like an excellent way to displace the energy of the waves without shock to the ship...now that is a sentence

[@richrepublican3493]

Boy, that bow cuts through a glass like sea just beautifully. Like a row boat.

[@daniellee5147]

I love the design. Looks badass!

[@georgefowler4682]

Rah, rah, rah. I would have preferred to see them actually perform in heavy seas .... sans music ...

[@erichaskell]

Reminds me of the swept back bows of WWI era warships. Maybe we forgot their value until recently.

[@EVAUnit4A]

The _U.S.S. Zumwalt_ perhaps...?

[@BarrettL1970]

Looks perfect for the Great lakes at first glance.

[@ericcriteser4001]

Reminded me immediately of a Great Lakes whaleback.

[@Mr91495osh]

When ships are this big and this heavy they don’t have to split the wave, they can smash it.

[@johnrflinn]

Brilliant!

[@welshpete12]

I understand these ships are better in rough seas then the older designs, do you have a any footage ?

[@am3835]

I've seen Polarcus Alima at our Port. The design is very unique up close.

[@gtmalalo]

Beautiful ❤❤❤ and also the music 🎶 in the background 😍 👌 ❤

[@cinnaco]

Great backing song !

[@paulsimmons5726]

Now, that's thinking outside the box on many levels. Has anyone thought about downsizing this design to a more personal-sized craft rather than the commercial-sized ones in these clips? It certainly looks like a good design that could be used for many purposes and applications.

[@Tomm9y]

Many of the plumb bow designs have incorporporated some of the concepts. However for light displacement vessels (Volume v Weight) there are different considerations, as the deceleration etc. may be less when riding over a wave.

[@nikkibuccolo7487]

Im sooooo buying 2 of these.

[@bigkiwial]

Be a hell of a lot of fun on those bridges in a seaway!!

[@raymondhoyland61]

What's with the silly music?

[@williamthebutcherssonprodu227]

Raymond Hoyland stock music

[@bill605able]

If there is no narration I personally prefer a low volume innocuous tune. Just saying.

[@StekliCujo]

Yeah, that description just about sums it up.

[@stranraerwal]

@@shawnyoung2105 : well, there is nothing to be said about "banging in bad taste". Some people are simply primitive and vulgar-can't be helped.

[@dougutubeify]

Yeah, I feel sea-sick now

[@magapickle01]

Surprised ocean going vessels didn't start out with that design . Makes sense

[@savedbygodsgrace.9058]

Neat design safety and comfort 1st.

[@marcbach5880]

Really best looking!

[@stucknmud4323]

Great,,, a video of pictures,,,

[@harveydecker6381]

Very interesting and informative. Thanks

[@robertmiller4664]

The front of the boat reminds one of the Me 323 Gigant from WW2. Strange looking!

[@jeffmoore4266]

brilliant.i'll have a blue one and a green one thanks!

[@marcosaugustoferrarini2804]

Very smart!!!

[@MartinReiter143]

Why not show us what it looks like out of the water? Or at least below the waterline.

[@johnnyllooddte3415]

they did

[@catatonicbug7522]

1:47

[@krigry32]

When this concept was launched in 2005 the team behind it was quite open about being inspired by the viking ships.

[@WildBillCox13]

And the high metacentric makes it likely to capsize. What were they thinking?

[@stupidburp]

I would like to know how many of these ships are built to some ice class standard. If it can handle very rough seas and light ice it should be good for polar waters.

[@petergoodall6258]

No actual video - genius innovation!

[@denisoko8494]

No innovation, this reverse bow design was used by vikings and slavs for their raider ships 1000 years ago, and more than 2000 years ago by Egyptians and Greeks!

[@markroeder2491]

So, do you have any testing data or video of the ship in operation?

[@cekiert]

I bet in rough seas, the crew feel like a spray paint can rattling around. More so then a stern cabin setup. Does the beds come equipped with a 5 point harness?

[@indridcold8433]

The one with the huge opening with a slipway on the stern would make an excellent whaling vessel. Hopefully it will not be used as such.

[@Leutchik]

It's hard to believe that this drastic change took so long to discover. Wave tanks and computers have been around for many decades. How did this radical redesign escape the notice of marine architects for so long?

[@whyno713]

If I was a billionaire my luxury ship would be a X-bow with flat space in the rear for water activities and a basketball court 😎🤑

[@butlerdawgs78]

Does it scale up? X bow cruise ships?

[@andrevenger]

10000 years and we're back to the same design as a trireme.

[@michaelwykeham6449]

The only strange thing is that this has been so long in happening. A relation of mine designed a fishing boat for himself back in the early 60s, with the wheelhouse forward, now everyone is doing it.

[@maxj0930]

What does the ship named “Vessel Name” do? Also, why is that same name on 2 separate ships? I am confused...

[@russcattell955i]

Go on, have a guess !

[@kevingarver9752]

I liked the picture of the two ships that had the same name " VESSEL NAME ".

[@waqarghulam3548]

I love watching x-bows in rough seas

[@samfrancisco8095]

I must have missed that part.

[@makethman007]

its like a tumbleholm design at the front

[@ObviousSchism]

It would be great if someone put some video on KZbin about these revolutionary ships

[@marusak72]

Laws of hydrodynamics must have change a lot last 10 years

[@kevintobin8554]

I would think that helipad could blow right off of there with a big enough wave, watching this new design seems like front is too heavy, do they have one with the super structure aft ?

[@joeyjamison5772]

What colors are they available in?

[@g.r.4853]

So what does it look like other than a much sharper bow and curved. what about where it counts, underwater.

[@jaynelson9617]

Anyone know the title of the soundtrack acoustic guitar background music?

[@sheridanbaldwin8629]

Some of them ships almost look like the great lake ships but newer looking ☺

[@markbozz153]

Fugly as hell, but evidently more efficient.

[@SCOTTBULGRIN]

A very old concept with a new take on it.

[@team3383]

like all the "revolutions" - Tesla isn't named Tesla for nothing ...

[@QueenDaenerysTargaryen]

Good picture🖼️ s

[@deandeann1541]

It seems to me that in a hurricane the portlights will be punched out, which in those circumstances could likely be the beginning of the end.

[@dagwould]

What is the below waterline shape?

[@bentackett6299]

If I was a lot smarter I could have designed this

[@dm8867]

ben tackett If I was smarter I would understand what I just saw

[@Bubbles99718]

Probably CAD designed.

[@TPQ1980]

This was likely a product of multiple fluid dynamics simulations that tested various permutations of bow design. You're probably smart enough to be involved at some level in the process. Go back to pre-computer days and yeah, most of us would be too dumb to innovate most modern developments. Took real genius and inspiration back then. Now its more about time and processing power and soon human input in the process will be minimal. Tools designing tools.

[@robertbabic80]

Ben Tackett good day! This was designed more than 2000 years ago. In my country, Croatia, they were building (beside 4 other types of vessels) same vessels for Roman empire.

[@bentackett6299]

Mighty Vicious Good day to you too! I believe it!

[@JoeMama827]

nice video. The next time I'm in the market for a $200M ship I'll definitely give you a call.

[@IbnBahtuta]

The X-Bow ships look really cool. They look natural, a bit like a fishes head.

[@normand5847]

A pointed bow ship looks like a sharks head.

[@jamesjames3525]

Looks like an normal ship turned upside down! Interesting!

[@dproffessa]

Soooo, after all these years someone finally designed an aerodynamic ship. Took them long enough

[@phstudio100]

Is this a sales video? I have no idea why this would be in my feed.

[@abswood77]

Would of been nice to see some live footage 🙁

[@jacksonemory4358]

Look at the revolutionary design! Looks a lot like the Norse longships to me

[@SpiritofDaniel]

IF you loose power in a storm, the bow will weathervain downwind. Plus the ride will be like a rollercoaster.

[@Bubbles99718]

Most likely designed utlizing high end CAD. Wish they talked about how iy was developed.

[@villageblunder4787]

But how do you do the 'Titanic' shot from the front of the bow!

[@twizz420]

Use another, smaller boat?

[@sebrassino]

Silly music, only images. These are the channels youtube should act on. Not the ones that actually create usefull content.

[@chuckvan1568]

sebrassino Exactly. And not persecute the gun channels.

[@alegnalidem9870]

the polarcus one was the ship of my cousin before

[@Slipmahoney21]

That wheelhouse must take a hell of a beating in rough seas!

[@Rorkazak]

Reminds me of a pickup truck.

[@BagoPorkRinds]

We shall nickname them the El Seaminos!

[@scotchsoda3165]

Reminds me of a Mullet........business up front, party in the stern.

[@johndoecake]

white font on white background? u sure u wana do videos op?

[@insolentstickleback3266]

Music was fine, if it had offended me I would have used my "NOT," painted on arm and adjusted the volume myself. Making bad comments on the internet over trivial things is simply poor behavior. Nice video Ship Facts thanks for sharing!

[@gathererhunter8414]

It was a horrible choice of music is all. If you truly like the creator then let him learn his lesson so he can make better videos

[@okbutthenagain.9402]

Stickle back...So IN YOUR OPINION they are making bad comments are they.. Well seeing as they HAVE AN OPINION and they don't like the music and said so That's their OPINION. Whether or not they should turn the volume down IS YOUR OPINION...Something YOU are keen to deny others...Hypocrite much?!?!?!?!?!?!?!?!?!!?

[@insolentstickleback3266]

Look Trolley McTrolltwat. this is simply a comment about behavior. Thank you for providing such timely evidence to support my "opinion," have a nice life :)

[@gathererhunter8414]

Silencing opposing opinions rather than arguing against them is bad behavior.

[@pegasusted2504]

I thought it was lacking TBH in the information department, could have done with a lot more.

[@danbasta3677]

I would imangine these new ship designs as well as the technology put into them will eventually be put into place on the Great Lakes shipping, which should hopefully alleviate any further shipping disastors like the Edumund Fitzgerald had experienced back in 1975.

[@johnv341]

Looks logical and seaworthy. Look forward to seeing how it handles really bad weather.

[@MrThenry1988]

Makes sense to me.

[@FeldwebelWolfenstool]

...kind of like pre-Dreadnought ships...

[@crgkevin6542]

And many of the early dreadnoughts themselves. Many battleships andbatlecruisers built before and during WWI had very similar "ram" bow designs like what is pictured. They were olower down, but that provided the added benefit of behaving both like this, and the asvantages of the bulbous bow.

[@InventPeace1]

TIME 1:46 Looks like 2 bottom halves together, I guess like they said the above water line shape reduces wave slaps & pitch acceleration/deceleration to keep speeds up or power needs down : less up & dn displacement friction/drag = more forward movement.

[@michaelevans1838]

Interesting. Obvious but overlooked. I dont know why the music was chosen.

[@martinzenor7449]

So it basically is a rubber ducky design?

[@jeffknox1370]

In those calm seas, i bet it would do just as well going backwards.

[@stevedoe1630]

These vessels were initially designed for Offshore Support Vessels operating in the North Sea. Rugged vessels, with tight frame spacing below the waterline. A bit overkill for Gulf of Mexico operations...ROI is lower, and day rate is higher. As long as Oil Major companies continue overpaying to suck oil out of the ground under the oceans, then it’s no problem at all. These are engineering marvels. Typically great welding, depending on the constructing shipyard. Bulb iron stiffeners, instead of angle iron. Dynamic Positioning Systems. Bridge layout is very effective for operations on the stern. And some of the best crew quarters in the world’s marine fleet.

[@mikeythesquid1427]

and if it capsizes. you can just keep going :)

[@philliptaylor502]

mike dunn -the bourbon dolphin didn't, it sank, i believe that was an Ulstein built vessel too.

[@twizz420]

Huh? It's not an upside-down boat... Put down the bottle

[@indridcold8433]

They rather look like an upside down, capsized, conventional bulbous bow ship. I think someone modeled the ship design with a starting point being an upside down ship. It looks live a very sturdy design.

[@hage3760]

ムツゴロウみたいでかわいい❤️

[@twinturbocoyoteftw]

Sensible to put the captain where he has a good vantage point. Even though he probably never looks out of the window to only stare at a radar image!

[@jimbarron9939]

I suppose it would be far too much to ask for a shot that shows what this hull looks like BELOW THE WATERLINE? Nice images in the video but the actual reality would be nice to see as well.

[@ShitStefanShoots]

Well, have a look at 1:45 again

[@jimbarron9939]

While _technically_ that does show a two second glimpse of "below the waterline" it is straight on from the side only and is impossible to determine the shape of the hull (cross sections in ANY of the three planes). The information content about the hull in that shot is "not significantly different from zero".

[@Squashed8Ball]

Stefan Schmitz While technically Jim could be an intelligent human being the intelligence quotient of his brain is not significantly different from zero.

[@Newzchspy]

The SS Meteor had this design and this was common on Great Lakes Freighters back in the 1880s and 1890s. NOT at all a new concept.

[@douglasscott5623]

I just looked at some pictures of the SS Meteor, don't look nothing like these X-Bow designs. Maybe it's just me IDK...

[@CaptainRon1913]

I'd like to see one in action with heavy seas

[@pcka12]

Sure I’ve seen that bow on a dreadnaught from the turn of the 19th/20th century, an old idea come again?

[@JosephStalin1941]

I don't think this concept is too far off from other designs over the past 200 years

[@retiredyeti5555]

Would have liked to have seen how it operates in heavy seas, not just slides showing it in fairly calm waters.

[@watkins65]

? does this improve parametric roll?

[@patrickbuick5459]

I think it is more for pitch than roll. (Just about used the wrong axis term.)
