Final mission would be to put solar cells and cross the pacific
Ambitious... i like it
It would, but he would need more skill regarding building errorproof design. Putting wires randomly in the hull, connectors get loose, same with pushrod... comeon - those are rookie mistakes. With skills Daniel has he should not not be making such silly mistakes...
@ yea for sure, the redundancy is nice but it would be able to work for days on end without any hiccups. One day he’ll get there
Circumnavigate the globe! 😂
Have a search for seacharger, it’s a solar autonomous boat that went from California to Hawaii and almost to New Zealand.
Love that you put the random interactions with strangers in the video, really gives it a nice touch.
im very like anti-social but i enjoy listening to other peoples convos its relaxing
@@hahafunnecat6162 So am I, only place i enjoy talking to other people is when i go to the markets when i can, everyone is so nice and theres a story behind everything that they are itching to tell (also a great way to get freebies)
It makes me yearn for pre-COVID times
I hated this with all my soul!
@@hahafunnecat6162 Maybe you wanted to say you are asocial not anti-social? Anti-social is when you hate people and want to kill them all, you are fighting against society. I'm asocial and I very much hated this convos, it made me cringe much.
its honestly amazing how he made this hull float, it goes against every single rule when youre making a boat and it still stays upright
Its not all that amazing
because it's easy to make things float, brother. bettef hull shapes just make things more efficient. rafts are terrible hull designs but simple and good enough for what they meant to
If the battery can support the boat for a few hours of autonomous sailing, you should consider adding a depth finder that maps the path you take and maps the depth of the path in like a 5-10 ft diameter on the lake floor and see how long you could go with one mapping a lake/pond on a calm day. That would be pretty sick.
Definitely second this. I commented the same thing .. a year later. Whoops!
sir you must use a magnet motor free energy device or a very small radium reactor (20 cm diameter)
came for autonomous boat, stayed for depression-era mega-sturgeon story from random passer-by.
That guy seems like he has some stories.
Yeah, that was awesome. Love how he dug up depression-era photos to go with it too.,
I love it when people just enjoy these kinds of things and stops by to tell a story. People can be surprisingly wholesome
Wholesome honestly
same
There are countless books on hull design, and you've somehow happened to plot a course around all of them.
The second i seen it was going to have a flat bottom I shook my head.
I saw the hull and shape... surely... doh
But A for effort.
Ikr?
Tall, narrow and flat bottomed
The three things your boat should not be
Well said.. as soon as I saw his Hull shape I knew it was bad.. should by a cheap Chinese rc boat to convert
I love it
Ship stability is an interesting subject. I graduated from a maritime academy last year with a third mates license and during my time at the academy I got to learn the basics for the subject. The cargo ships you see have many containers below decks as well as a comprehensive ballasting system. It seems bizzar and complicated from the outside, but it's not incredibly hard to understand seeing as your average Mariner has to learn about it.
Edit: You're representing the 206 well my friend!
Stability of a vessel depends on distance between centre of gravity and centre of bouyancy (metacentric height). Metacentric height is basically a lever that implies stability against overturning. So when we are lowering centre of gravity(by adding cargo or ballast below the current COG) we aslo lenghtening metacentric height that keeps the vessel upright.
@@unit666ful I am a licensed third mate. It's been a while since I took my ship stability class, but I still remember the basics.
"After building a boat, I now have no idea how boats work"... fantastic quote
Realization of ignorance is the first step to the knowledge.
This is the basis of the Dunning-Kruger effect.
Boat videos from rctestflight are honestly top tier
All videos from rctestflight are honestly top tier ftfy
I hope there's a boat channel somewhere that makes occasional experimental plane videos :)
I realy like these boat projects. all the people stopping to talk is fun too. It's very similar to what happens when I'm doing my own projects. Even if they're not as advanced as yours.
Yeah, the random people stopping by is a really fun intermission
I like it too. When I flew my electric acro plane in a park near my home many years back, people asked me even if it was a petrol engine and such things 😳. I eventually got tired of the "how much it costs" question. Lately, I maiden a little one and a failsafe at that small park surrounded by houses encouraged me not to fly there again hahaha.
Yeah its actually kinda fun meeting people at random, it used to happen to me when I went fishing all the time. The local crackheads and old men would stop by and have conversations and tell me about way back when haha.
So what projects do you make? :)
@@JaviRP97 I was always annoyed by the cost question, but even more annoying was "Where did you buy that from?"
I know it's mostly that they just want to ask about what I'm doing and don't understand enough to ask pertinent questions, but the default question shouldn't be commerce related. I think most people have just lost touch with the idea that you can actually make things.
"Rudder 101" - put the rudder blades (yes, 2 of them) directly behind the propellers
Yeah
yeah i second that....
Why? Having it between the props works just as good. Look at Bismarck, three props, two rudders placed between the props, not behind.
@@darkiee69 If you lived on a boat, as I do, then you would know why (prop wash directly over a rudder greatly helps steering). Also, the situation with the Bismarck is a great example of why it's better - the ship failed all sea trials of steering with rudders disabled and the problem was highly influential in the ship's demise. Thanks for highlighting that.
@@ianb4801 but with rudders disabled it doesn't matter where they're placed. If they don't work they don't work. And this boat seemed to steer without any problems.
you know what would be cool in the summer you could have your Autonomous solar plane fly above the boat and be a relay for the boat on very long distance which could improve you signal overall
When you hear "so um i built it out of dollar tree foam board" you know its gonna be good on this channel.....
Yes, this channel is good
Agreed danyels a lad
That's the go-to material for building easy/experimental RC aircraft. Flite Test channel is essentially made of the stuff.
I love foam board, it’s great for quick work with a knife and glue gun. Admittedly not the most durable or sturdy of materials tho ;)
Keeping dollar tree in business with our foam board demand for going on 3 generations!
The thing you're missing in terms of stability is a keel, a heavy fin extending below the bottom and into the water. Keeps your boat straight up and makes steering much much easier.
Designing it so it doesn't get caught in vegetation would be difficult.
As someone suggested in the comment section, for this conditions, the solution would be to have a wider bottom, right?
@@ashtonbrown4318 long keel instead of a fin or bulb style maybe? Nothing to really collect on.
@@JaviRP97 a wider bottom may help with staying up right a bit, but not with steering and stability. It would also have to be much wider and would lok weird. You typically see keels on such boats.
@@ashtonbrown4318 I'd say a keel shaped like a "reverse shark fin" would slide over any vegetation.
Would love to see a version 3 with a deep dive into how container ships work and how to implement the same principles in your smaller scale boat!!!
The underwater portion of container ships (also known as the draft) is absolutely huge. And because it’s so deep, it’s also reinforced, making it heavier. That’s why those ships stay stable. They have a deep underwater portion, and a very heavy underwater portion.
Also the containers go al the way into the depths of the ship and the layout of the containers is plotted out so that the more heavy containers are at the bottom
Cargo ships have containers that go all the way below deck, not just on top. This will help further lower the center of gravity.
container ships are usually loaded so all the heaviest cans are as far down and center as possible, too.
And also their hulls are made of iron several inches thick. The hull alone probably matches the weight of the cargo.
They also have keels full off lead lol
The crew also press down on the deck to hold it in the water during transport.
@@rmdcade1717 hahahahaaaaaa
Another autonomous boat, nice! I love these projects.
"This boat will go slow, for high efficiency"
**Adds 15lbs of ballast to keep boat upright**
Better to have ballast than driving upside down
15lbs of ballast ain't much. Some rc model boats require WAY more than that. Take for example Harbor Models Mr Darby (formally Dumas), or Invader, and the Dumas large Carol Moran kits. These large displacement hull scale boats and others like them need up to 60lbs of lead ballast, which sometimes include large gel cell or lead acid batteries. And they are slow efficient and powerful ships.
I thought of getting a Mr Darby awhile back but didn't want the hassle of having to lug all that weight to the pond.
A way around that issue would be to engineer some flood chambers to bring it down to it's water line.
His boat had alot of "sail area" above the waterline and along with the flat bottom caused issues. Especially with all that wind and chop. Look up "High winds push cruise liners" and see what I mean.
In the end, it didn't sink, and it seemed like he had fun. Sounds like success to me.
@@blkft You've missed the facetious point completely.
@@luma8212 You've missed the facetious point completely.
@@ryanokeefe12 ok
I love that old guy, stories from old people they always gave me a weird feeling, I don't know why I Just love it
Same, it's because no one talks to anyone anymore
@@bigsteve6729 that's kinda sad but true
I think a V shaped hull would improve stability in the waves.
Debatable
U shaped maybe more effective at doing that?
And an x bow for looks
We need to come up with a gyro-stab for RC boats.
@@kogger8519 You could duck tape a quad on top and put it in autolevel modem
I don't know if it's been commented already. But i work in boats, and autopilots DO have different PID's for different sea states as well as different speeds. Maybe you can come up with different steering modes. That would help.
As someone who works in the industry, do you have any good recommendations for books about control systems?
Engaging
@@TylerSimsMechanical buff nope. Just autopilot manuals maybe?
@@TylerSimsMechanical You can use Ziegler-Nichols method to tune the PID´s , thats easy and effective : see Wikipedia, Ziegler-Nichols method
I was wondering the same thing, like, how difficult would it be for his autopilot system to automatically adjust the steering strength with the sea state.
I watched my dad build a boat in our backyard and as soon as I saw yours I knew it would be too top heavy...great job you pushed through so cool.
"After building a boat i have no idea how boats work"
Yup, that's what I noticed at the very start of the video.
It's a solid body to displace water. And that what it does.
Engineering defeats or findings are not made by copying other designs. I feel his journey with this boat was awesome, it showed drive an ingenuity.
@@drew859 Maaan, i was just quoting a funny sentance i heard you don't have to be so serious
@@drew859 Innovation often comes from going back to the basics
I love the random people encounters. It's great to see people getting interested with these projects
13:42 That battery warning almost gave me a heart attack.
Same here, but I didn't realize it was in the video untill I saw this comment, instead thinking it was a glitch.
I love the story from the passer-by. Thats exactly the kind of stuff you always hear while fishing. Beautiful.
I find the thought of a little boat with lights navigating itself at dawn quite comfy. I also loved the guy with the sturgeon story, later he came back and remembered the boat's name, seems like a pretty chill dude.
"after building a boat, I now have no idea how boats work"
Ahh yes, Floor is made out of floor
It's really amazing how far and how successful he was before realizing he didn't know what he was doing. It's a remarkable human quality and none of the great things humans have done would even have been attempted if the person understood exactly what they were trying to do.
I understand this comment. I have owned a sailboat for 40 years that has 40% of it's total weight as lead in the keel. Whenever I see a power boat with a fly bridge and ten people up there I do not understand how it does not turn turtle. I cannot even imaging how the cruise ships remain upright with all the top-hamper they have.
@@pforce9 they mainly have huge ballast tanks filled with water in them that they can shift water in using pumps to keep the centre of mass in the correct place same for all huge hull boats
@@yuruna1661 You do understand that both he and me were rhetorically speaking. This guy designs autonomous boats and I have been a seaman for 40 years. Neither he nor me, need any explanations as to how boats work. Thanks anyway.
next part: autonomous long range wind sailboat, like for new project
wind sailboat? aren't all sailboats using wind
I agree! Sail power is the future! This is a thing that must happen...
Notice how the "woo hoo"s get progressively less enthusiastic as the snow continues?
As a Michigander, I understand.
Lol same
I love snow/cold 🥲
Everyone chill with the criticism! Damn. He is just having fun. How many of you could do better?
This is the best comment on this video, I couldn’t agree more!
Every single person who has seen an actual boat could do better...
@@BradRLeBeau everyone knows what a boat looks like, however being able to build that without breaking the bank is a different story. Chill. He still completed the mission and had fun. That’s all that matters.
@@TheSpaceMedic0516 well common knowledge for one person might not be common for others. Where you live and surroundings shape your common knowledge. It shows from the comment section, the errors on this hull design was so obvious, but to others they think these people pointing errors are keyboard warriors.
@@TheSpaceMedic0516 I just worry that he's gonna lose it. You say 'without breaking the bank' but there's $600+ of batteries alone, plus motors, controllers, GPS, cameras. That's a lot of money to lose to save a couple of hours and $50 of materials for a better hull design.
A keel might help the turning ability. Also making the keel out of lead would lower the CofG and increase the stability.
since I was a kid I wanted to make a submarine or a plane that would be capable of cycling the world and take pictures and film some of it and then see how much it weared out at the end.
That would be amazing to see if it was possible to autonomously sail transatlantic for a extreme long range mission
@@louisgilliland6617 yes, I wanted a live feed of where it was at all times but now I would be happy to at least see a recorded version of it, how it dealt with big waves, the ocean storms etc... I think it would be awesome, but at the same time it could be really boring, who knows
@@geovani60624 it would be interesting to see how it would achieve this. Perhaps using solar panels, how much of the time would be spend sailing and how much would be waiting for the sun to rise to charge the batteries. And in this down time , how much would it drift?
I had the same idea as you,maybe a hybrid plane with gas and eletric motors and solar panels,and a huge camera in the front to record It all xD
@@louisgilliland6617 at the same time I alse had an idea to leave machine in the forest that moves around at night and takes pictures of the night animais and stuff and at the end of a year it would go back to it's initial point and I would see all the adventures it had
It's always so nice to see people who are genuinely interested in RC projects rather than those who say "you can't do that" or "you can't be here I'm calling the police". That lady who took the picture and the guy talking about the fish are so cool. Need more people like that in the world!
me seeing the hull shape "oh no". I recommend giving architectura navalis mercatoria a read it is a 300 yo old book that will tech you the basics.
lmao. Nowdays we can compute stability of hull. (which would be a nice school project, btw)
@@heyhoe168 I know but it can't hurt doing it the old fashioned way just for fun.
@@dr.johnh.watson2444 oldschool hull is the best for fullscale wooden construction. Since it is a small model with a wider choice of materials, copy might perform quite poorly.
@@heyhoe168 would probably improve underwater steering though
@@danksanchez4324 without proper byoncy to weight ratio it will not improve. Also dont forget the weight distribution.
The Vibe, The Vibe of a boat making its way through rough water, all on its own. Truely amazing!
Wait till you realize that you can live in one and cross entire oceans at the same time. I almost get the shivers to do it all over again.
Maybe now it is high time to embed our updated sonar, Daniel? Not that one I sent you last time, but brand new stuff, compatible with ArduPilot.
Perhaps a Deeper Chirp + to log the bathymetry maps (and fish) automatically.
@@ademczuk My sonar connects to the Pixhawk directly, so you can see the actual depth right in the mission planner
Very nice autonomous project, thanks for including the "sturgeon man"
And this boys and girls is why a boat has a keel and not a flat bottom.
Big boats have big flat bottoms
@@kolmepukkia That's not a big boat is it?
And Everyone, Together:
*!!!Redundancy!!!*
I love that you show your problems and fixes, it gives a realistic view of the project. The reason big ships are so much more stable than model boats is because stability scales with the 4th power (volume x length) so if you make a hull 1/2 scale it is 1/16 as stable. That's also why model sailboats have giant keels-- sail area goes down with scale squared but stability goes down with 4th power so model sailboats with sails that "look right" need extra-long keels. Looking forward to the next video!
Drug traffickers be like: *"write that down, write that down!!!"*
The dude talking about sturgeon was cool man
This channel has been in my top 5 favorites for like 5+ years
Came for the Drone Boat, stayed for the giant sturgeon story...
the single hull bashing through the waves is the "Abeille Bourbon" a french emergency tug boat
nice seeing it there
In a PNW lake somewhere, a giant, old sturgeon is telling its grandson, "In the olden days, we used to bite onto chickens hooked onto a rope. Pull hard enough and you'd get a mule for dessert!"
Bahahahahahahahahahaha!!!
😁
Hoping to see a downward-facing camera on this. Gotta catch you a megasturgeon
I hope you do your own "FPV to space" high-altitude balloon-drop glider.
Amateur UAVs in controlled airspace make the FAA angry...it's one thing to do it with just a few people and not be too public about it, totally something else if you air on a youtube channel with 279k subcribers.
There's always the great David Windestal who did that in Sweden! He was one of the early pioneers in the RC field!
I love the conversations with the strangers that you have
I love your enthusiasm. Cables, always add in a loop of cable. Pipes use this to take up heat or pressure variances, even a single 2" coil of loose cable will prevent things becoming unplugged and you really have to get that prop so it doesn't touch the water.
When I was a kid I shaped a skim board out of pink insulation foam board and tried to glass it with polyester resin. It melted right before my eyes.
That was a lot of time and money back then. Glad it didn't melt you whole boat!
13:42 I got worried briefly … then I remembered I have a desktop.
Love how people just come by and instantly get into it loving your idea
Glad to know there's big electronics / autonomous geeks like me out there, awesome work awesome job
So cool that you went back to look up those amazing photos to go with that fella's sturgeon story. I had no idea they got that big.
2021 - The year we bring back sturgeon mule fishing.
I like the way you include the people and conversations in the video.
I rebuilt part of the rail, and a large portion of damaged area on a 13 foot Boston Whaler using fiberglass and bondo resin. The resin gives you about 10 mins of solid working time if you make sure to mix in small batches. I find it easier to paint it on thin, lay fiberglass, then touch up with more resin on top. It gets you really good saturation pretty quickly that way, and prevents you from needing any large amount in your container for too long. I did need to use. If you want it real shiny, use the bondo resin as paint by sanding the fiberglass until relatively smooth, then paint a layer of resin over it.
Take note: bananas are known to be bad luck at sea. There is a boat where I live called 'No Bananas" and they fly a banana flag with a cross through it.
“After building a boat, I now have no idea how boats work”
Yay. This series is back.
Fantastic! I look forward to seeing what your autonomous boat can do. Congratulations on your work!
You are a creative and passionate engineer. I admire your design and problem solving skills too. Keep going!
The laptop low battery alert had me panicking. Great vid again!!
**watching the first 4.30** how does this thing float with that weird hull shape? ohhh.....
The end part deserves a whole video!!
I love watching the boat videos! They are so satisfying!
I also loved how you used weights to balance it, The design is awesome!

Comment for the Algorithm gods. Welcome to engagement land.
I too am engaged, heed me algorithm!
Wow much engagement.
Engaging
Is water wet?
Amen, add me too!
It's easy to be critical of design shortcomings and failures to implement the lessons learned by previous generations, but here we see the learning of a try-er who willing shares successes and failures with humour and a good grace. Thank you.
some how this gives me so much chill just sitting with a cup of coffee and enjoy your super design
thank yu
my uncle had a death trap of a car in the 80's affectionately named "Yellow peril". fits the boat pretty well
15:51 the man looks like: I got the monster . :D
Bonus footage was a prime 👌 treat for a great boat adventure story. Look forward to the next one.
I love that your still using that DX8, I have the same one and I still use it.
Banana Slug! 🤣🤣🤣
Have you never heard of a keel? :D
You mean a seaweed hook???
@@rctestflight would be enough if you just glue a metal rod on the bottom of the boat(not going down just flat from back to front) thats how container vessels work (like sort of)
@@rctestflight A keel is different from a keel board / centreboard.
That story was so cool, and the way you worked it into your video!
Came here because the title interested me as a drone pilot. What was really interesting was the talk of sturgeon! As an angler myself it was fascinating to hear about a sturgeon being pulled out of the water by mule, I don't doubt that has been done!
"Can't go out without a name"
Gotta love the PNW.
Container ships are so stable because they have a ballast system that can basically flood the hull with as much water as it needs depending on the cargo it's carrying and the condition of the water it's traveling in
Glad you're having fun
I can feel your passion when you are touching it.
"Having a wide range of skills are crucial for projects like this one" ...Hmm, I wonder if Skillshare has a lesson in boat hull design and engineering? Just kidding, couldn't resist that comment. Thank you for your videos, always cool and interesting!
Because of it's size and the way the numbers work when scaled down, your boat would probably be much more stable if you added a keel, that would help reduce the rocking motion from the waves, and resist lateral wind and/or shallow currents. Also given the massive battery endurance you have now, maybe add a small fish tank pump, the kind that engages automatically when submerged, so that if somehow water starts leaking in, you have an additional failsafe? (Coupled with raising the electronics above the level the pump engages to keep them dry)
Underated channel. Love this stuff
Love this channel! Keep up the amazing work!!
"it's got a bit of a gangster lean, but that's alright" haha, good stuff.
this was so funny!! i work on boat and could see problems from start!! and see more comeing but lets watch to the end
I love also those interactions with people going around!
I like your design method. trying to think of a solution yourself before just copying someone else. great video
Just imagine replacing the 15 pounds of ballast with batteries
When your sponsored by skill share yet you clearly didn’t use it to learn out to make boats
my toughts exactly
No hull test either
Let’s see your boat?
For anyone wondering, the real boats are so bottom heavy because its made of steal, not paint and foam
@@JMRabil675 They also have a huge water ballest
Definitely one of the best projects
As an Aussie, I'm very envious of all the snow you Americans have been getting.
This really inspires me to do my own stuff, I'd love to make it track storms or something haha
Tons of Comments and nobody talks about the MONSTER in the lake?! :D

Awesome effort to get all that working
