I always think it’s funny when you apologize for the picture or sound quality. Maybe I’m different but I could not care less about those things when it comes to CZcams. I don’t come here for the production value. CZcams is all about the personalities and the content. You could film these videos on your cellphone and I’d find them just as entertaining.
You should build it on the trailer or your gonna have a real hard time getting on the trailer once it's built .
17:57 Hey, wouldn't it make it overall easier if you were to build the trailer first?Now you've got the pontoons done.Build the trailer place the pontoons on the trailer and build the boat on the trailer. Otherwise.How would you get the boat on the trailer afterwards while it's in your shop🎉❤
Hey you should go take a tour of Brunswick on Hadley rd in Fort Wayne.
Hey Chris for rolling flicker you can use: Flicker Free from Digital Anarchy, if you're still using FCP (not sure if there any internal solutions, I haven't touched macs in a while). Or Deflicker tool that comes with DaVinci Resolve. Both gave me pretty great results in the past.
Hey Chris, from an engineering perspective, those welds need re-enforcement. Your joins are central and I would you recommend doing 2 things: 1. Weld an alu belt (500mm wide) over your centre line weld and then 2. Weld at least 4 horizontal struts over this join for reenforcement. Your support struts should be at least 1m in length and 100hx100wx4mm material width.
The way you have carried out the work so far is great, but as an engineer, I would not certify this structure currently as it is.
Definitely agree. A spa pool in the middle is also going to be putting a huge amount of bending into those pontoons and hence, those welds are going to have to be even stronger than the ones used in the original pontoons structure. I would be tempted to run some additional strengthening channels along the length of the pontoons also
This is starting to be reminiscent of the camper
Just as another note, what gauge is the alu? It may only be gauged to the size of pontoon bought. In that case you ought to weld disks inside the pontoon, spacing them every 600mm to increase rigidity.
My thoughts exactly.. or incorporate a truss system also don’t forget the horizontal forces between pontoon’s will need structural diaphragm… so the pontoon’s supporting the engine(s) don’t run over your hot tubbers while passing your outside pontoon’s ….? 😂
Funny I don't weld, not an engineer but a machinist and this was my very first concern.
Never seen a boat designed using quadtoon mechanics, impressive!
A barge
I think I know who Chris reached out to for the engineering on this project.🤔🤫
@@tech_abraham5617barges are the pinnacle of naval engineering
Chris, I appreciate you and your team taking on this ambitious project. That being said, it IS ambitious, please listen to some of the concerns in the comments. You have naval architects and structural engineers pleading that you make some design changes to ensure the success of the project. The design process is not one straight line. Your first design is changed a lot as the project moves forward. Don't be discouraged to change your initial design. You have a wealth of experts in your audience who are happy to help!
That being said, I love your projects and I hope it all goes well for you!
Didn’t even notice the time lapse scrolling till you mentioned it, don’t stress about it. boats looking good
Its the shutter of the camera vs the frequency of the light (LED lights sometimes have PWM drivers). There are plugins that can remove the fickering in post production (edit).
*You should run your calculations by an engineer @Chris*
*If you put the hot tub on the bow you are going to have issues getting on plain, you want to keep the bow light*
*I have a lot of experience working on boats, I think you are going to find you have overlooked a few things on this boat build*
I agree. And with as much as this is going to cost, some simple thing that they could have done differently could sink (pun intended) the entire project after they have spent a fortune and months making it.
He has he said this in the first video.
@jiminauburn5073 it's not going to sink lol
Or run holding tanks, placed throughout pontoons from middle to rear, to hold hot tub water when underway, then pump into the hot tub when you are using it. Definitely want to reduce that bow weight, when motoring. Of course, the weight of the holding tanks in the pontoons will likely create some significant, additional stress on the, already stressed, joint of the 2 toons being welded, so hell I dunno....
@@jerrywilcox9890 Why are you so sure it won’t sink?
Listening to that explanation of the flotation I am so glad we use the metric system.
That was ridiculous! All those conversations where in metric it's just 1 litre = 1 kilogram.
And a man is 100kgs.
😂😂 same here!
They will use ANYTHING other than the metric system 😅 I mean, when you hear American news compare the size of an astroid to, and I shit you not, "half a giraffe" . . it's time to turn off the TV..
He was listing everything at nearly double their actual weight, and still had a few thousand lbs of lift to spare, so at actual weight he’ll be less than half submerged.
I would imagine that the pontoon tubing wall is guaged according to length. Some sort of sleeve should probably be in there across your seam and out a few feet either way.
Yea the factory splices have a 25in disk pairing the sections together..... the welds will probably over time tear. IMO
Yup I agree, I did this when splicing truck frames, we used 6" diamond pieces to bridge the weld on the inside.
I'd put money on those welds cracking. Not dissing Oscar in any way, but even to backyard engineer the welds look like they will be under crazy stress whenever the thing hits a wave and flexes.
Yep there gonna crack in half
Going to sink like a rock
That is going to crack without a sleeve
I agree, a sleeve is a necessity
I was imagining the toons snapping in half the first small wave they hit 😂 the forces will be great on such a tiny seam weld
That was my first thought.
@@Jax0238 I would think that the rigidity of the boat when completed will help to redirect the forces in other structural parts of the boat. Adding to the fact that there will be 4 toons.
Should call it the Tritanic.
But it's quad not tri
@@benthebuilder6934 true but tritanic sounds better!
Showed this to my boat guy, we are excited to see such a unique vessel out on the Columbia and Willamette ! He is worried ab the hot tub location and design as well as I am so we are keeping our fingers crossed that you are safe when testing !
Notice the factory splices have a 25in round disk tieing them together......I wouldn't skip that
I agree. It seems like their joint between the two they welded together will be under enormous stress, and I can see it breaking. Plus the other splices have the external pieces of aluminum spanning across the joint, giving them more strength. They need to fix that or it is going to break and sink them.
yup! especially with the length of this thing whether you wish it or not those pontoons are structural pieces and the location of the splice is EXACTLY where the maximum stress will be.
B is for "Let it sink so that we can claim it on our Insurance"
When you have expectations like a teenager what do you expect. It's cool to watch... It's a win win for him.. it's like watching the British motor channels in the states... Lol 🤣
If the first thing on top of the pontoon is a continuous beam the length of the pontoon’s it should be stiff enough.
You should connect the strakes on the ends together where you joined the tubes. That gives more support. You probably should add a strake on the other side too.
I’d be worried about the bending moment of the length, but that’s probably why it has 4 toons.
I’d imagine adding a supporting plate going over the welds of the pontoons would add a fair amount of strength. Don’t think it’d be a bad idea either
How are you planning on transporting it? A trailer build first would have made things easy.
Agree with the comments on lack of strength of the pontoon in the area of the welds Oscar has put in. I an ideal world, to make longer pontoons you would start with larger diameter tubes so that the bending moment stays about the same. Need to calculate for vertical bending of the structure, when each end is on the peak of the wave, and midships is in a trough. With the payload (people) in the middle. However, rather than reinforcing the weld area, I would make sure there is sufficient strength (including triangulation) in the upper structure, that ties in to the tubes towards the bow and stern. By the way, what you are calling stringers are actually deck beams. Stringers go longitudinally.
Great project. Don't forget the lifejackets!!
They'll have to bisforbuild a giant trailer to move that thing too, better get started so they can be done by the end of next season
I can't imagine how they are going to get it into the water. It is so long and any boat ramp will be at an angle and severely stress the weld points in the middle as the back end starts to float and the front end is on their massive trailer.
Crane
Boat lift like they used to get the other boat in/out.
That weld spot connecting thr long tubes, wouldn’t that become the weakest area of the longer tube now. They only removed a three or so foot section off the end. That end hardly had any of the weight of the boat stressing it, but the middle will have a lot of stress how is that not going to buckle?
So they will need to only invite super models to play on the floating pontoon hottie spa??
I personally can’t wait for the mini pontoon build with the extra nose cones
Same, I think I'm more excited for that than the main pontoon boat tbh lol, looks like theyd be a blast to be honest!
@@kylewise3111 a blast of water to the face, but same difference lol
@@kylewise3111 unless they balast the heck out of them they will just roll. Its basically a 55 gallon drum. The easier way would be to use all 4 bows and build a mini pontoon dingy.
@alexandercarril4486 that makes it sound sketchy, but generally more sketchy = more fun lol
Especially when this one inevitably fails.
I used to work at Vigor marine in clackamas. You guys really gotta back grind your starts and stops on those welds or they may start cracking. Also somewhat nervous that there is no sleeving. Good Luck!!
Okay Chris, you've got four of those pontoon ends; we definitely need a stubby catamaran tender! Two stubby pontoons, a little bit of framing, maybe a stretched webbing deck!
Fill the pontoons with expanding foam, closed-cell spray foam insulation is highly moisture resistant. If you hit something you won't sink. It is just a thin Aluminum...
This is a great idea. It might be too buoyant though.
@@davelangford2439 Not sure there is such a thing as 'too bouyant' for pontoons, think all it would do is add some weight
air vs foam in the tanks, easy thing they can test with one of the cones though (for floatability)
edit- Also the things are sectioned, so the long sides already have ~6 different sections that would need to be breached (and I don't think it would be all that easy to 'fill them with foam' consistently)
@@austinh1028 fair enough, I don't know anything about pontoons. I really hope it works out though. Been following this channel since very near the beginning.
Don't do this... the instant a crack forms in the pontoon you'll have hundreds of pounds of wet foam stuck in there, even if it's moisture resistant
This is the absolute worst idea imaginable.
The pontoons are segmented for a reason - puncture one segment of 1 pontoon and the boat will still float enough to get it back to shore.
Adding thousands of pounds of foam to sealed bouyancy tanks will just increase the weight of the vessel.
"It's correct for everyone that works here but" 😂😂😂
Does anyone else think this is going to break in half?
Unfortunately it will be his 2nd boat sunk,well this won't sink since both won't snap at the same time
Nope, it's massively strengthened by having 4 pontoons
@davelangford2439 I hope it works out,because this is super cool..was sad to see the ship partially sunk..
@@VooDooV6 Same. I've followed BIFB since pretty much the beginning and always want their builds to go well. I really want to see more Burntican though!
Top Gear made a Hilux boat. Disasters are fun to watch!
Won't the extreme pontoon length cause flex and cracking around the welds? Might have been safer to have kept them as individual units mounted solidly together.
They should run some I-beams longitudinally to reinforce that center seam. Should have connected the strakes to help with that also.
I agree. I would probably cut them into smaller sections and make several watertight sections in each pontoon. When one of those welds crack, they will fill a whole pontoon with water and it will flip over.
This is the most exciting build for me to watch you guys do. Idk why because I love all your builds, but this thing is awesome!
I've been watching CZcams for about 12 years and have never been so pumped for a buil like this one.
Awesome as always.Thanks for sharing and taking us along
The foam idea inside the poontoons is used in other boats to make them very safe... Boston whalers are made this way I believe... love the show!!!
This is awesome. My favorite episode will be when they move it to the water 😂
A 40ft trailer to build this on seems like a good idea. Then you can build a jig to keep them straight.
Should go straight really well’ the trick will be turning this sucker. Looking forward to seeing this fun build!
shouldn't be an issue at all especially since he's running multiple engines.
I agree. He might want to consider bow thrusters in the hot tub box or something
Might need some bow drives for making docking and undocking easier.
Never be able to dock it on a windy day, even with twin engines, it is so long and tall
So freakin’ cool! Can’t wait for the next video - thank you!
@bisforbuild lol my welding teacher in college build a boat for himself and got a little carried away with the height of the cabin and he had to "renovate" to get the thing out at the end. boat turned out great though he has went down to the bahamas (from canada) multiple times. love your videos you guys are an inspiration. cheers boys!
Love to see this. Chris always pushing his boundaries into the unknown, such a great learning experience. Will everything work out perfectly on a brand new design on a first ever B is for Boat build? We hope so, but what makes such fun content is the trial and error and drama along the way. I think Chris knows this and is a genius for attempting this build.
Y'all are crazy, I like it!
Such a cool project. I am keen to see how this turns out
What a MONSTER!
Good time now to start thinking ahead about logistics - transporting your finished product to the waterfront.
I have to admire your ambition. Looking forward to seeing this thing come to life.
The timelapse banding issue is usually due to a mismatch between camera shutter speed and the refresh frequency of the lighting. I very rarely shoot video, but I have encountered the same issue a long time ago and I believe I solved it by matching the shutter speed with the frequency of the electricity supply.
100% spot on with this.
Something to think about regarding the pontoon joints and lift strakes. The lift strakes add stiffness to the pontoon, the welded joint won't have this reinforcement. The strakes need to be tied together so the welded joint won't have to take the entire flex load. This build will be epic.
The lifting strakes on the pontoons also provide extra strength to the pontoons to prevent them from bending or breaking. Have you given any thought to adding some aluminum angle to augment the area where the 2 pontoons were joined. I expect your deck to provide some support to keep the pontoons together, but it may not be enough.
Awesome idea.
Wow! It's HUGEEE!!!
You might want to add a tube in the pontoon’s to make room for bow thrusters. Thrusters will really help with a boat that length.
Love the new build for sure
So excited for you guys and a tiny bit jealous 😢. Can't wait for the finished product 😂❤
I would definitely continue the mounting angle across the welds for structural strength.
When its done id love to go out on its maiden voyage , Im here in Minnesota and have been on the water all my 66 years of life ! I think down the Mississippi would be epic ! Start at Stillwater Mn. down the St. Crouix to the Mississippi to Lake City then back ! Lots of sand bars and islands to party at and maybe camp out, with big bonfires and some barley pops !
If you put the hot tub in the back you could use the engine cooling as hot tub heating :)
I would honestly do your motor transoms before u get to far on those toons so they are easier to move and prep now! I absolutely love this build
This looks to be coming together really well
I consistently enjoy your series. I particularly appreciate when you mention the 'target completion date.' While I enjoy the camper series, it lacks a clear objective. As an IT professional, I'm accustomed to working within set deadlines and budget constraints, as I'm sure you understand. Sometimes, it slips the audience's mind that these episodes aren't released chronologically, leading to surprise when a new series interrupts an ongoing one. My suggestion is to provide more insight into your project timelines, so we can eagerly anticipate upcoming videos. Thank you for your valuable content!
They don't get time lines they get done when they get done.
he stated in episode one he wants this done for this years boating season (which already started...and ends around october). chances that'll happen? 1%...tops
Best build yet!!!
The journey is half the fun. You have an outstanding channel! I subscribed immediately. Thank you for sharing it.
2 things- 1 move the hottub to the back all that weight in the front youre going to take water over the bow and swamp the boat.
2 your going to want to mount 2 engines on the outside corners. Turning that thing in the wind and current will be extremely challenging. Look at the large premier brand pontoons for inspiration
This is awesome
Transporting and launching it will be fun.
*The formula for calculating the floatation of a pontoon is F = (D - W) / V, where:*
F: is the floatation force
D: is the density of the water
W: is the weight of the pontoon
V: is the volume of the pontoon
To calculate buoyancy, you can multiply the volume of the pontoons by 62 lbs. per qu. ft..
Or you can use the "Twenty Percent" Rule to ensure that you build a safety margin. This rule has two ways to go about it:
•Subtract 20% from the capacity plate's total listed weight capacity and use that as the maximum permissible weight
•Calculate the total weight of your passengers and cargo and subsequently increase the total by 20%
*I didn't want to take the time to type all this out so I copied and pasted it for you, hope it helps* 😅👍
He already did the calculations 😂😂.
@@jerrywilcox989012:31 *Referencing the 20% rule I quoted above, you can see that according to Chris's own loose calculations he has miscalculated*
*If his estimates of the pontoons were correct the max weight capacity will likely be closer to 13,000 or 14,000 lbs not 17,500 lbs*
@natesmemes1794 they already calculated it lol.
@@natesmemes1794 they can handle it.
The b is for build team are so talented! Just normal guys with ambition and focus!! Well done guys
Great project. My concern wouod be a small leak allowing water into a pontoon. While not deep, even a 1/2 inch\ 1cm water level would cause massive problems due to free surface effect. Multiple bilge pumps, baffles and inspection ports needed.
Don't worry about the strips on the time lapse, your content is A++ either way! Keep doin what you do, appreciate you!
I think the 27 in pontoons also reduce the bending of the outer pontoons. So the inner pontoons become almost like a girder to reduce bending moments. I am all on board with the idea of spraying closed cell foam into the pontoons to make them both stronger and more boyant in the case of an incident. Looks like being an incredible lake boat but your going to need a large float to transport it and also need to take into account lifting points for launching.
Strangely enough I can’t wait to see this boat done so that we can see the trailer you build to move it! 😂 love this content!
That buoyancy calc made me love the metric system more particularly for the conversions.
Cool build 😎
Nice project, it is huge! Hope it will turn out as great as you wish. I would suggest to cap and seal those middle two pontoons. Much easier to leak test and leak proof that way then connecting both to the a big box.
At least you are out there making it happen brother. As an engineer with lots of marine experience, I’m routing for you. PS, I’m stoked to see what happens when you get the right props on that yacht, you may find yourself spending a lot more time with it when that happens!!!
Those aluminum welds will unzip after floating the boat. The weld itself may hold but the metal directly next to the edge of the welds will fail.
What makes you say that?
Agree with that. The Welds loking bad.. I hope they dont crack.. Or they got a free Submarine.
They should probably weld supports around the joint.
Yup metal fatigue is real. there's going to be a lot of compression and tension back and forth with every wave.
1st or 2nd ride id think those welds will fail. And the boat will sink
Note of attention! Avoid welding the pontoons under pressure. They could explode!
Check videos alerting about welding rims with inflated tires.
they were pressure testing after welding, you could see them remove the bung and release the pressure before welding after
They didn't weld them with air in them 😂😂.
so far there's like 20 on going projects and all half attempted, nice
B is for SQUIRREL!
@@iconiccreations2492 lmao yo
have i missed any comment where the manufacturer of the pontoons said yeah we specked these out to be fine when welded together and made twice as long and with the interrupted lifting strike that i think is also there to make the whole pontoon more ridged
These guys are smart , I’m sure they will reinforce the welded units. Right b is 4 b
😊
Dear Chris, congratulations on your new built. I would like to point out some things that concern me about the Pantoone build. first of all you are welding two independent sections and those sections are held by a tiny weld in the middle, you should consider that that’s going to be under a lot of pressure and the weakest point. it could be the failure point on the pontoon sections , if you see the original pantoon sections they each have a long brace that goes from the beginning until the end of each section and that is to give strength to the cylindrical sections. Consider placing 2 continues support beams two brace each side of the new pontoon sections welded to brace them so it mitigates, putting all the force on the welds and preventing the pantoon from bending in the middle and reaching a catastrophic failure. Congrats to you and your team on embarking on a new journey. I really enjoy watching your videos.
Exciting project. The camper as well. And then there is the Italian yacht. The draw on this build is the boating enthusiasts.
I'm excited for this project
Crazy ! Impressive :)
This boat is huge
That thing is going to be massive can't wait to see the trailer that you put that on that's going to be just as big and massive
When those waves crash into the hot tub, I have a feeling if you have any waves, one end of the boat could be 8 feet higher than the other.
This is gonna be wild.
Youre seriously like me. I start many projects and only chip away at them every once in awhile and it takes years to get anything finished haha. But that also has to do with finances and time
In regards to the black line in time lapse, it’s probably your lighting. Clough42 has a good video about how he just updated his shop lighting because of that.
Thanks for your awesome works and videos. I guess, as certainly already pointed out by other, that vertical stripping is probably due to frequency of your LED light and the frame rate of the camera. My best guest is to ask the LED light provider as they are certainly aware of the problem and solutions. Thanks again for the great work.
I would be happy to come help you break it in when its ready to float :) Gona be an awesome party boat!
Probably wise to have the 2nd floor cover the helm. Will make operating in the rain less unenjoyable.
To set the width, you should place the pontoons in your shops door jam with a 5/8" spacer on either side
Watching the build with the jumpacan in the background I was thinking it would be cool if the design included a way to drive a car onto the boat.
building a yachtoon cant wait to see it done
oscar un super soldador solda oro con plata y cobre con acero bravo !!!!!
haha this has to be your nuttiest project. when you showed how long it was going to be it really made laugh. can't wait to see this behemoth on the water and the looks it gets.
The spam call commercial was funny because it reminds me of those infomercials, “does this happen to you?” You guys should lean into that a little. 😂 Nice work boys!
@BisforBuild something to look into is railing around the “sun pads”. If there is low rails people will be allowed to legally lay on them while underway.
Also I’m slightly surprised you didn’t go with pontoon stuffs plastic toons. I saw a guy put lights in them, made a really cool party vibe. Maybe look into that for v2
Seeing that being pulled behind the the dually camper truck is gonna look nuts lol
The length of the pontoons are my concern. Do you plan on turning? Do not go out in big waves, the pontoons will be on the crest of the waves with the middle unsupported. Eventually, it may snap the welds.
My worries are
1) the resistance from bending under weight. Constant shifts minuscule over time does what it does to all metals.
2) resistance to ea pontoon with their massive length rolling in/out in between each other (trying to separate from each other) outwards.
Those calculators do t factor a lot of what nature can do to numbers that only account for a static vessel. Boats are not as static as we think they are.
Theres some massive physics that will be challenged when fully weighted and in water that is constantly moving. It’s a crushing weight that being floated by pontoons above the water without any body below the water to set a balance from what’s above the water vs below.
Just my worries, wishing the best for you all ♥️✊🏽
Loving this build. I just can’t help but think how much easier those buoyancy calculations would be using metric! I realise that might be a contentious topic, but it really is so much easier. And I guess it will still float, however you calculate it.
Loving it, did you hint at a build at the old shop/house you bought back in the day - You borrowed money off your mum but paid her back back in the day - that place. Loving the new content but I may speak for a few saying I miss the old shop. Not big enough for what your're doing now but you and your team in that place was inspiring.
displacement calculations get so much easier if you'd simply tolerate the metric system... but suppose football yards and bald eagle eggs will have to do til then
