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.

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 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

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)

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

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

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.

Realization of ignorance is the first step to the knowledge.

This is the basis of the Dunning-Kruger effect.

All videos from rctestflight are honestly top tier ftfy

I hope there's a boat channel somewhere that makes occasional experimental plane videos :)

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.

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.

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!

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.

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

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

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

Same, it's because no one talks to anyone anymore

@@bigsteve6729 that's kinda sad but true

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

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.

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

Same here, but I didn't realize it was in the video untill I saw this comment, instead thinking it was a glitch.

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.

wind sailboat? aren't all sailboats using wind

I agree! Sail power is the future! This is a thing that must happen...

Lol same

I love snow/cold 🥲

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.

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

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.

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.

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

Big boats have big flat bottoms

@@kolmepukkia That's not a big boat is it?

Bahahahahahahahahahaha!!!

😁

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 too am engaged, heed me algorithm!

Wow much engagement.

Engaging

Is water wet?

Amen, add me too!

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.

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
