This was a major nostalgia moment for me. When I was at university (University College, Durham, England) in 1969, I decided to participate in a "Raft Race" which was an annual event at that time. Most of the entrants cobbled together junk and anything that would float, and hoped for the best. I had some limited woodworking skills, so I decided to make one from scratch, and the idea was somewhat like yours, but at that time I had never even heard of hydrodynamics, so my raft was much cruder. Each hull top and bottom was was 10 foot long by 10 inch wide by 3/4 inch thick pine from the local hardware store. I tapered the ends of the boards somewhat like your technique, and then applied lengths of fiberboard 12 inches wide vertically like in your design. It was held together by roofing nails about two inches apart!!!. I then painted it over and over again, until I could be sure it would last at least an hour in the water. I made two kayak paddles from more or less similar materials. I then recruited a friend who was a long-distance athlete, which I was definitely not. The course was about a mile along the River Wear which runs right through Durham, round the castle and cathedral. There were about 15 entrants. I had no idea how well it would perform, and never had the opportunity to have a test run. Off we went. The raft paddled incredibly easily, steered well, but sluggishly compared to a canoe or kayak. There was not much freeboard! It seemed too easy. There was one other entrant who was quite fast, but their poor construction made them stop and make adjustments quite often. They also had six paddlers whereas I only had two. Eventually their raft came apart and they all took a swim. After that it was just keep going. I could tell we had a leak in one of the hulls but it didn't slow us down much. We won. Thank you for reminding me of this crazy stunt from 50 years ago.

"this is a hydrofoil" Amazing cliffhanger. Also 1 8 6 5 0's is a bit of a mouthful, which is why they're usually referred to as eighteen-six-fifties. Added bonus it sounds cool. Please keep up the amazing work. You've inspired several of my own future projects.
The more correct term would actuallt be 18 65 0, because the name tells us that they are 18mm in diameter, 65mm long and the 0 is because they are round. But I also call them 18-6-50s.
@Kristoffer Klungland, you are both correct and wise: "18, 65, oh (or zero)" is the proper and best way to designate them, but "everybody" says it the way @Andrew Wilhelm recommends. Now, how can we "get even" for that wicked teaser? It is incredibly cruel to dangle that with no comforting mention of when, what, and how. Maybe I'm more vulnerable because from the moment I saw the thumbnail of this vid, I was thinking "hydrofoil"!
Several years ago, I retired and became bored with so much free time. I stumbled across some TH-cam videos regarding skin on frame kayaks and canoes. So I built one, and then I knew there was away to take that knowledge to the next level and began looking at Catalans. They came in all different sizes. I started looking into building one with the skin on frame design concept in mind. I started to design the Catamaran I wanted to build, but I was stuck at how to keep the deck sturdy enough, square and sufficient storage space. Watching this video answered all of those questioned and also answered a question I had on propulsion. I had not considered solar power and using trolling motors. Thank you for this video and other video's that I have watched that have given me a treasure trove of knowledge from which I have put into actual practice on little projects. Please keep up your awesome work and the diverse video content. So much information, explained in very concise form, coupled with the fact you make it all so interesting. Truly awesome work.
At the thumbnail seeing the length of this video I was a bit scared but after seeing the first minute i couldn't stop anymore!! Fact after fact its amazing how many details you are respecting (in every single video I've seen till now) and I really appreciate it that you will go full time with your videos. I'm looking forward to seeing the boat flying over the water with (definitely) more than 5 knot. ;)
i didn't even notice the length when I put it on - and now that it's done and I came here to the comments I saw your post. I had *no* idea I just spent an hour watching it. Great stuff as always. 👍
This channel is very interesting and I love it, but very little if any of what he does is applicable to actual industry engineering. Things things learned in an engineering degree and job allow you do better understand all these cool projects he’s working on, but in most of these projects you’d be better served being a carpenter or other trade worker rather than an engineer.
@@Corndog4382 after all most money goes to marketing, and then engineers have to find a way to make that product work with the money left except if you were an engineer in the 90s for mercedes then you had all the money you needed to make the best product possible
@@Corndog4382 Well, very little of what is taught in an engineering college is considered cutting-edge or even acceptable in industry-best companies. There's a reason why 'academic' and 'professional' are so vastly different. A degree will let you learn the basics and bare basics only. Can ideas from channels like this be turned into mass-produced stuff? I don't think so, I completely agree with you there. Does the content allow for some innovative problem solving on real jobs? Definitely. I'm an automotive-engineer turned agricultural-engineer. Channels like this, or other domains of knowledge expand your thinking in a way that allows you to build on the basics and apply new ideas to old stuff. I'm no stranger to woodworking and carpentry, I'm also super familiar with automotive sheetmetal & fabrication work. But I've never built a boat. This channel's video on boatbuilding and fiberglass strengthening allowed me to apply fiberglass strengthening to some home-built furniture. I'm working on a commercial greenhouse project where metal was too heavy and wood was too weak for a certain aesthetic. Guess what the answer was? Fiberglass. Saved me money, and basically the project would have gone a lot slower (Or not gone ahead at all!) if not for the cross-domain ideas that come from channels like this.
I've watched a lot of this chaps videos, and I'm convinced that no one, no where in the universe knows more than him! Bravo, you are awesome! Love the videos!
I cannot thank you enough for the diverse content and in-depth, precise, science-based understanding that you provide with your experiments and projects. I regard you as a modern day DaVinci :-)
The reason for the tapered hull shape in the rear is to minimize turbulence. As you said, it takes energy to impart motion to a fluid mass, or any mass for that matter. If you create vortices you are changing the direction of motion of the water, which costs energy. The goal is to part and replace the water with as little disturbance as possible, whether that disturbance be waves or vortices. But if your hull is too long and skinny then you wind up with a lot of surface area relative to the volume. The more surface area the more friction. There is a sweet spot between these factors for a given speed and displacement.
Your MIND must never get a quiet moment, what with the myriad of conceptualized thought processes and ideas that are constantly flowing. Your absolute precision craftsmanship and ability to explain to the viewer the "what" & the "why" of the procedure sets YOU, Sir apart from the rest. Truly magnificent. Thank You so much for sharing. Greetings from Ontario, Canada.
Love the detail and formulas you include to explain the build. All your videos are so bloody detailed and interesting...I've learned so much and appreciate what you do.
I love the Catamaran video. I'm really interested in seeing the hydrofoil in action. Will you be actually deploying it in the water? I've had wanted to build a Catamaran but your video gives me hope. Also, what if you can collapse it for easier transport on a trailer plus build up a berthing and head area. Just some thoughts.
FULL-TIME Tech Ingredients?? That is like the best massage I got in a long time! I just love your stuff. Highest quality science content together with Applied Science IMO.
It is a good video, but it's hard to believe that you got a massage from watching it ;). This would be possible with some audio-driven vibration, though.
Your channel is the best example of Adult Learning than any on the net. Your presentations are always interesting, understandable and better yet, inspirational. I want to build everything you make.
One of the best science / howto channels that I've ever seen anywhere! You've found the perfect mix of science, common sense explanation and very cool projects that are obtainable by an average person. I've watched every video that you ever put out and I can't wait to learn about the next project!
Having been an old Hobie Cat guy, one pontoon gets you up to nicer speed as it begins to hydrofoil. The trick is never to flip. In +10 years, I never did (unintentionally). Very proud of that. It is very doable due to the asymmetric developed shape of the Hobie pontoons. Never needed a motor. Thanks for doing this. Good luck with this venture. Nice to see the fundamentals explained instead of just a list of todos.
"This is a hydrofoil" Drops the mic Amazing content guys, looking forward to the foil upgrade, in the meanwhile I'm sketching how to do a swamp cooler based on the ideas from the previous videos, I always had a hard time finding suitable materials for the mesh, but the shower head idea was genius Cheers
so the real sweet-spot balancing is going to be getting just enough solar panels up there to maintain the more efficient 'foil' cruising speed. And a tiny (and light) enough battery (or capacitor?) for the short blast of power needed to get it up onto the foils!
@@willdarling1 Honestly, the burst power is covered, so long as the motors can hold together. Remember, he said they will only be using 100 amps out of a potential 1,500 amps of safe output.
First thing I thought of when he started talking about drag in the water - make it a hydtofoil. But, I thought, you'd really need to up your hull-sculpting game from bent ply to do it well. Was I wrong??? Guess we'll find out!
This gentleman is smart, easy to understand and is a must see. I've been on many sites of DIY projects and this man was riveting and I actually finished watching from start to finish.
love your guy's videos Mike! It reminds me of weekends and afternoons with my grandfather, always teaching us new things and inspiring thinking out of the box.
@@cenariusbg I want to know what job he has (had?) that lets him tinker around with all this stuff. Surely he can't do all this in time after work???!?!?
Sure they could do this after work, so far they haven't posted videos that frequently, and if you leave your relaxing periods for just two or so hours before bedtime and use the rest of the time after work for projects you'll be amazed at how much you can get done in weekdays. Then do 4-5 hours on weekends, maybe in the mornings, then spend the afternoons goofing off. It helps if you're the kind of person that plans ahead a bit though, I'm not that guy so my time is spent very inefficiently in many cases, but I can still tear through most tasks I put on my weekly todo list by wednesday.
TI: Wow...to everything in this video. The planning & engineering, the demonstration of the method of construction using a 1/4-scale model, the amount of thought that went into modularity and allowances for alternative means of propulsion. At one point, I found myself wondering, "How does he know all this stuff?", from batteries, to types of wood, structural members, and coatings, to the need for "sacrificial aluminum" keepers on a pivoted motor mount...etc. Amazing depth & breadth of knowledge here! The final mind-blower was in the last few seconds of the video, where you answered the question about why you used a high-speed prop on a boat that shouldn't be able to go more than a few knots with the simple statement, "This is a hydrofoil"...and then just grinned as you let the viewer make the connections that led to the downstream implications. 'Twas a joyous "Holy sh!t!!" moment. You sneaky bastidge...and I'm sure you realize I mean that in the nicest possible way. This is exactly what I was referring to in an earlier comment I posted on another video, about your creation of "story arcs"-not only within each video, but in the larger context of potential future videos. It's a level of subtlety and continuity of *_both_* creativity and content that, for my part, demands payment of gratitude via explicit acknowledgment. Superbly done, amigo!
"This is a hydrofoil" right at the end. Oh yes that brought a smile to my face. The tails at the back of the pontoons were also a bit of a giveaway as well. Your channel is not only entertainment. It's a resource that can be researched for later projects. Distilling whisky comes to mind......... Just a thought, maybe another foil, rigid surface sail possibly? Coupled with this design it would go like stink (a nautical term).
I’m 81 and I’m through with the boat thing, but I find your documentation to be first rate, thorough and presented in a matter that I understand (I was a Supervisor and Industrial engineer for a large farm equipment manufacture in the Midwest) so the current subject has very relevant sub topic info, I think I’ll pass one the boat build but the fiber glass info was very enlightening. Count me in.
As I was watching I was thinking to myself: "You know.. this is kinda sounding like it's being built with a hydrofoil in mind." then I got to the end: "Ah. There it is!" Can't wait for part 2!
Currently building a 21' fishing boat with an old school 40's - 50's salmon troller look. Raised front deck, five window cabin with portholes, large cockpit with round stern similar to a tug. However trying to incorporate modern features without being so obvious. This is a displacement boat and I originally drew it up with electric propulsion ( trolling motors ) but could not find any suitable solution for speed and endurance so I have been considering dropping in a 40 hp outboard hidden under the rear deck. The thing that got me to watch your video was the name " Tesla ". I love that guy, his engineering and problem solving skills and creativity, a gift from God. You have some Tesla in you too, I may have a smidge but with no education. When people see my project under construction they always ask if I am an engineer. Pretty funny as I am a 70 year old high school dropout that never built anything. The propulsion system you put together was intriguing and well thought out. Please share with me how that worked out in in your sea trials and if any modifications were required if you would be so kind. One of the best videos I've seen.
You are amazing. Science and practical application together and as an engineering physics graduate which combined both these facets, as an audio nut, and as a lover of fun/potentially explosive projects…and boats…I find this to be my favourite channel ever. Thank you all so much.
Just watched your catamaran build and loved it! I was thinking you were going to add hydrofoils to the build along with a Sail or two. Maybe next time?
This is so awesome! The quality of your content and the sound science behind every project is truly inspiring. Keep up the good work and thank you for promoting science and engineering
🎉 I am very glad that you took the plunge 4 years ago to dive in full time with this awesome channel. Your content is very high quality, informative, fun, and well explained. Thank you for everything you and your team do here!
Man, I love this guy. If I had had instructors like this when I was in school, i might have been able to build that hi efficiency lateral generators. I seriously love this guy.
The information I get by watching this Chanel is really spot on. The explanations are dumbed down enough to give me a full understanding of the principals applicable to the project. Bravo Sir. I'm in!
When I saw the video before watching it, I thought one hour is a little long, maybe I skip this one. After watching it I wonder where that hour went, good job!
This is so cool. Having "crewed" on a trimaran and owning a small 16 foot mono hull i was impressed by the video content and the ability of the teacher to describe the process of construction. my congratulations! looking forward to seeing progress. bravo!
Good thing I scrolled down the comments. You said it! (But when I was in school, I would have been distracted by the image in my head of the “fair lady’s perfectly curved shapes”.)
What a great tutorial on unique boat building. Having watched and listened several times, my conclusion is that I hear and learn new information with each repetition. Thank you
I was just thinking that this guy pretty much defines "dangerously scary". At first glance he seems like some dude building stuff at home and then you realize he's a casual super genius.
This build is beyond my expertise, but it is informative and I am entertained by your Knowledge and ingenuity. Thank you for providing this video, I thoroughly enjoyed it.
This channel is so good, it is hard to compare with anything else on the tube. Remember, subscribing isnt enough, you got to click the bell, CLICK THE BELL!
I remember watching the DIY speaker video, and I couldn't get my head around the quality of the video, vs so few subscribers. I was hooked by the jet engine, and I was glad you were picking up subscribers. I finally had a spare hour to really take in this video, as I love all the engineering details. This channel will continue to pick up more support, just keep up the great work, and newbies will have more to binge on.
This is the third time over several years that I have watched this video. I Think its awesome. also I have watched other videos done by you. Best wishes.
I watched this same video many years ago. I still appreciate all the technical discussion. My interest in buying or building a boat have been renewed. Especially after spending a week in Ocracoke NC last week. Thank you.
I would love to see that thing come out of the water on a set of hydrofoils! I really like the content you guys produce, but the videos are often a little anticlimactic. This is an hour long video about building a boat. I would have liked to see it touch the water at some point and see the result of the engineering on the behaviour in the water. I understand this takes a lot of time to cover, but I hope you guys are able to do so in the future.
So you'd rather a 2 hour video? 3 hour? How long do you need it? Why does it need to have a conclusion. Thats like telling a car repair channel they better have that car running and on the road in one video, or else I'm a whiny little baby. If he takes 15 hours of video to build something, so be it. If you don't like it, movie along. The rest of us like it just fine.
@@mikeworkman3593 He could make 2 videos instead of one and include some footage of testing and performance. There is a sense of satisfaction in seeing the success of a lot of hard work. It would help the channel grow.
I love everything about this channel... there’s nothing quite like listening to a polymath to inflate one’s sense of intelligence by proximity, lol! Keep up the incredible videos and i’ll be watching with you all the way...
Link Age two things: a polymath is, by definition, someone of wide knowledge or interests, and judging from the breadth of topics this channels discusses I'd classify as being wide in their knowledge AND interests... It is NOT an indicator of one's level of intelligence or education as you seem to belive; someone's age or education level is not indicative of their ability to be a polymath. Shame on you for trying to reduce someone's passion for imparting knowledge into some kind of gatekeeping competition of intellect bullshit... Your teachers are ashamed of you, and you've failed at being a decent human being.
@@Jimisky go easy on him Jimi... I think he actually didn't KNOW what a polymath was... he does now though... 😌 See... here at Tech Ingredients we even learn from the comments section !! 🙄😂 😎👍☘🍺
@@peterfitzpatrick7032 Something must have happened here, a comment must have been removed. What an embarrassing way to learn, but you would be a real dumbass not to learn, even from comments no matter how embarrassing. It is a good example of learning the value of humbling oneself.
this is the best You Tube I have watched. Precisely what a novice like me needs to set me straight. Thankyou so much for your generosity and teaching skills. And you tube ... Please don't make it so hard to find professional minds like this. They should come up first on a search. Thanks again.
@@TechIngredients more like DIY low budget orbital ring. seiously I love your channel and it just keeps getting better. also since you mentioned stirling engines, I wonder if you could run a turbine on a continious stirling type cycle.
@@TechIngredients Sounds exciting! Cody'sLab also has some nice plans on his "Chicken hole base" that is supposed to simulate a space station on mars. Hoping to see some really interesting videos in the future with this announcement from you, as always :)
@@ARandomTroll hmmm...with the right gearing, you can get a spooling up and an rpm of 300,000 right up until it blows up and a piece of shrapnel slices through a critical bit.
Thought about foiling all the way through the video, so I was happy when you’ve brought it up at the end! Looking forward to how the project continues! Cheers!
I wish I had a dad like you growing up. I've always wanted to engineer things, pushing boundaries. Thank you, gentlemen, for your time and expertise! Hydrofoil, woot~!

I'm looking forward to seeing the boat flying over the water with (definitely) more than 5 knot. ;)
Nice into too
i didn't even notice the length when I put it on - and now that it's done and I came here to the comments I saw your post. I had *no* idea I just spent an hour watching it.
Great stuff as always. 👍
Just so you know I have died so from now on you will be talking to the dead version of me. Sorry for any inconvenience.
Nice to watch at 1.5 speed.
I lost track of time, Really enjoyed it 👍
This channel has the potential to be life changing. I might have become an engineer if I had encountered this at the right time.

This channel is very interesting and I love it, but very little if any of what he does is applicable to actual industry engineering. Things things learned in an engineering degree and job allow you do better understand all these cool projects he’s working on, but in most of these projects you’d be better served being a carpenter or other trade worker rather than an engineer.
@@Corndog4382 after all most money goes to marketing, and then engineers have to find a way to make that product work with the money left except if you were an engineer in the 90s for mercedes then you had all the money you needed to make the best product possible
it's never too late unless you're dead. become an engineer!
@@Corndog4382 Well, very little of what is taught in an engineering college is considered cutting-edge or even acceptable in industry-best companies. There's a reason why 'academic' and 'professional' are so vastly different. A degree will let you learn the basics and bare basics only. Can ideas from channels like this be turned into mass-produced stuff? I don't think so, I completely agree with you there. Does the content allow for some innovative problem solving on real jobs? Definitely. I'm an automotive-engineer turned agricultural-engineer. Channels like this, or other domains of knowledge expand your thinking in a way that allows you to build on the basics and apply new ideas to old stuff. I'm no stranger to woodworking and carpentry, I'm also super familiar with automotive sheetmetal & fabrication work. But I've never built a boat. This channel's video on boatbuilding and fiberglass strengthening allowed me to apply fiberglass strengthening to some home-built furniture. I'm working on a commercial greenhouse project where metal was too heavy and wood was too weak for a certain aesthetic. Guess what the answer was? Fiberglass. Saved me money, and basically the project would have gone a lot slower (Or not gone ahead at all!) if not for the cross-domain ideas that come from channels like this.
Imagine having a shop class using & showing these videos. In high school i would have been excited to build along with the videos.
this video is 1h long , yet its the most "pure condensed relevance" piece of knowledge i cam across on the tube .
thank you sir .
I've watched a lot of this chaps videos, and I'm convinced that no one, no where in the universe knows more than him! Bravo, you are awesome! Love the videos!
Yeah how does he know everything

I cannot thank you enough for the diverse content and in-depth, precise, science-based understanding that you provide with your experiments and projects. I regard you as a modern day DaVinci :-)
Didn't even fell like an hour long video. Wish I had a guy like him teaching in college!
Keep it up!!
I watch his videos at 1.5x speed. I can still understand them fine. I watch most youtube videos at 1.25x or 1.5x speed.
I've got to say you are the most succinct and eloquent teacher I have ever heard speak.
Do you think it's AI already?
LOL
@@giovannijoseph9580 I'm sorry, but i don't understand the question.🤔
@@jordanhorst6 just kidding...

It is great stuff though!
@@giovannijoseph9580 ahhhh, i get it.😄
Yes, and it appears he doesn't even have a script...smartest guy in the world...nice hat too!
It's amazing how you can make a 1 hour video this consistently interesting
The reason for the tapered hull shape in the rear is to minimize turbulence. As you said, it takes energy to impart motion to a fluid mass, or any mass for that matter. If you create vortices you are changing the direction of motion of the water, which costs energy. The goal is to part and replace the water with as little disturbance as possible, whether that disturbance be waves or vortices. But if your hull is too long and skinny then you wind up with a lot of surface area relative to the volume. The more surface area the more friction. There is a sweet spot between these factors for a given speed and displacement.
As a marine engineer i found your explanations great in real terms, wish I had your videos 40 years ago trying to lean. I just enjoy your channel
1 hour ago I didn't even know I wanted to build a boat.
... and yea: this is cool, but I really hope that he can swim as well. ;-)
They have already built a jet engine. I think 5 years is too long time for them!
ROFLMAO
i didn't even realize that the video was an hour long until i read this after watching it
@@upgoon4015 I was so captivated by the content that I forgot to look at the time.
This dude even goes into a technical deep dive of the youtube algorithm, that's why we sub to this channel.
Your MIND must never get a quiet moment, what with the myriad of conceptualized thought processes and ideas that are constantly flowing. Your absolute precision craftsmanship and ability to explain to the viewer the "what" & the "why" of the procedure sets YOU, Sir apart from the rest. Truly magnificent. Thank You so much for sharing. Greetings from Ontario, Canada.
I really hope this channels grows to tens of millions so that I can watch these videos 3 times a week at least!
I want to see this catamaran perform on the water.
Me too. I want to see it.
Do you already have a video of the cat on the water? I want to see it in action also.
What no maiden voyage?
Just talk no action. Why should I watch this video? You wasted my time!
Everyone died.
Every time I see a video from this channel I know I'm going to come away with knowledge about something I've never even thought about before
Love the detail and formulas you include to explain the build. All your videos are so bloody detailed and interesting...I've learned so much and appreciate what you do.
I love how wide, how all over, and how random of tech content you post.
Agreed!
Progressing through the project, technology and concepts are required out of the expected skill set. Excellent knowledge incorporating methods.
This is the most scientifically accurate
tech channel I ever seen! This hour has flown, oh well, has swum!
I love the Catamaran video. I'm really interested in seeing the hydrofoil in action. Will you be actually deploying it in the water? I've had wanted to build a Catamaran but your video gives me hope. Also, what if you can collapse it for easier transport on a trailer plus build up a berthing and head area. Just some thoughts.
I love this channel it's like 'Popular Mechanics' for the modern day.
Early eighties my dad tried PMs hovercraft using a homemade prop and briggs mower for power. Sadly it never progressed beyond the plywood formers.
Love those timeless topics that just keep on giving, days, weeks, and years later. Thank you sir!
Started watching for your audio builds and distillations, but have been enjoying the other content as well.
FULL-TIME Tech Ingredients?? That is like the best massage I got in a long time! I just love your stuff. Highest quality science content together with Applied Science IMO.
It is a good video, but it's hard to believe that you got a massage from watching it ;). This would be possible with some audio-driven vibration, though.
@@antibrevity You just don't know what my personal Tech Ingredients Laptop is capable of haha ^^
Yo, where's that hydrofoil video!? lol... I want to see more of this boat!
It was recently posted.
Your channel is the best example of Adult Learning than any on the net. Your presentations are always interesting, understandable and better yet, inspirational. I want to build everything you make.
One of the best science / howto channels that I've ever seen anywhere! You've found the perfect mix of science, common sense explanation and very cool projects that are obtainable by an average person. I've watched every video that you ever put out and I can't wait to learn about the next project!
Thanks!
I'd really like to see this project actually on the water- That is the real test... For the FUTURE?
Big cliff hanger.
Yeah would be great to see it in action
Love how you tie the engineering (math/science) of various disciplines with an actual project. Really helps learning, understanding and imagination.
Having been an old Hobie Cat guy, one pontoon gets you up to nicer speed as it begins to hydrofoil. The trick is never to flip. In +10 years, I never did (unintentionally). Very proud of that. It is very doable due to the asymmetric developed shape of the Hobie pontoons. Never needed a motor. Thanks for doing this. Good luck with this venture. Nice to see the fundamentals explained instead of just a list of todos.
"This is a hydrofoil"
Drops the mic
Amazing content guys, looking forward to the foil upgrade, in the meanwhile I'm sketching how to do a swamp cooler based on the ideas from the previous videos, I always had a hard time finding suitable materials for the mesh, but the shower head idea was genius
Cheers
so the real sweet-spot balancing is going to be getting just enough solar panels up there to maintain the more efficient 'foil' cruising speed. And a tiny (and light) enough battery (or capacitor?) for the short blast of power needed to get it up onto the foils!
@@willdarling1 Answer: Another Tesla Module
You just have to find a regular human showerhead - ones for special humans or extraterrestrials will unfortunately not work.
@@willdarling1 Honestly, the burst power is covered, so long as the motors can hold together. Remember, he said they will only be using 100 amps out of a potential 1,500 amps of safe output.
First thing I thought of when he started talking about drag in the water - make it a hydtofoil. But, I thought, you'd really need to up your hull-sculpting game from bent ply to do it well. Was I wrong??? Guess we'll find out!
What a fantastic speaker and educator. This is exactly the type of video I was looking for a first time boat build. Thank you!!
That's what I wanted to say... 👍
inspiring
This gentleman is smart, easy to understand and is a must see. I've been on many sites of DIY projects and this man was riveting and I actually finished watching from start to finish.
Ditto
love your guy's videos Mike! It reminds me of weekends and afternoons with my grandfather, always teaching us new things and inspiring thinking out of the box.
I’ve been sailing for about 25 years and finally I understand “hull speed.” Thank you.
I want to be just like the main presenter when I grow up
Same, I was thinking to myself, so old people could be funny and interesting as well?
@@cenariusbg I want to know what job he has (had?) that lets him tinker around with all this stuff. Surely he can't do all this in time after work???!?!?
Sure they could do this after work, so far they haven't posted videos that frequently, and if you leave your relaxing periods for just two or so hours before bedtime and use the rest of the time after work for projects you'll be amazed at how much you can get done in weekdays. Then do 4-5 hours on weekends, maybe in the mornings, then spend the afternoons goofing off. It helps if you're the kind of person that plans ahead a bit though, I'm not that guy so my time is spent very inefficiently in many cases, but I can still tear through most tasks I put on my weekly todo list by wednesday.
@@cenariusbg Old? I was thinking how young he was! :-/
Why do you want to grow up? Look at all the fun he has playing with his toys.
Most youtubers drag the video out to get to 10 minutes, Tech Ingredients here just lets 'er rip for a whole 'nother zero on the end of the timestamp.
True, and they are even trying to trim it down. I would like to know so much more about the physics behind every project. it's just so much.
I know eh? That hour flew by and at the end I wanted to know more damnit!!
I just noticed this was an hour long video. This channel is amazing!
Best comment of the day award from me. Lol!!
TI: Wow...to everything in this video. The planning & engineering, the demonstration of the method of construction using a 1/4-scale model, the amount of thought that went into modularity and allowances for alternative means of propulsion. At one point, I found myself wondering, "How does he know all this stuff?", from batteries, to types of wood, structural members, and coatings, to the need for "sacrificial aluminum" keepers on a pivoted motor mount...etc. Amazing depth & breadth of knowledge here!
The final mind-blower was in the last few seconds of the video, where you answered the question about why you used a high-speed prop on a boat that shouldn't be able to go more than a few knots with the simple statement, "This is a hydrofoil"...and then just grinned as you let the viewer make the connections that led to the downstream implications. 'Twas a joyous "Holy sh!t!!" moment. You sneaky bastidge...and I'm sure you realize I mean that in the nicest possible way.
This is exactly what I was referring to in an earlier comment I posted on another video, about your creation of "story arcs"-not only within each video, but in the larger context of potential future videos. It's a level of subtlety and continuity of *_both_* creativity and content that, for my part, demands payment of gratitude via explicit acknowledgment. Superbly done, amigo!
I've only watched about 7 mins so far, and I'm so excited there's still 53 mins to go! This channel gets better and better!
56:48 I imagined Smarter Everyday suddenly appearing, Kool-Aid guy style saying "DID SOMEONE SAY LAMINAR FLOW?"
*sniff* got some more of that...*sniff*... laminar flow?
JediNg135 lol
lol i thought of him immediately when he said that.
Yup....first thing I thought of.
haha
"This is a hydrofoil" right at the end. Oh yes that brought a smile to my face. The tails at the back of the pontoons were also a bit of a giveaway as well. Your channel is not only entertainment. It's a resource that can be researched for later projects. Distilling whisky comes to mind.........
Just a thought, maybe another foil, rigid surface sail possibly? Coupled with this design it would go like stink (a nautical term).
But this... does put a smile on my face
That smirk was priceless
I have thought about building a boat many times. You have given me many many ideas to improve my plans.
This guy is like the modern Mr. Rogers of science
Crazy, same way I described this channel to someone earlier today
very true
Struggling to stay awake just to finish watching; that's how much I like this channel.
You have the gift of blending 'over my head' tech with easily understood concepts. Your videos are highly addictive.
I’m 81 and I’m through with the boat thing, but I find your documentation to be first rate, thorough and presented in a matter that I understand (I was a Supervisor and Industrial engineer for a large farm equipment manufacture in the Midwest) so the current subject has very relevant sub topic info, I think I’ll pass one the boat build but the fiber glass info was very enlightening. Count me in.
Doc Brown: “Where we’re going we don’t need... roads!”
Awesome video! Thanks for increasing the fun technical content on TH-cam!
As I was watching I was thinking to myself: "You know.. this is kinda sounding like it's being built with a hydrofoil in mind."
then I got to the end: "Ah. There it is!"
Can't wait for part 2!
Currently building a 21' fishing boat with an old school 40's - 50's salmon troller look. Raised front deck, five window cabin with portholes, large cockpit with round stern similar to a tug. However trying to incorporate modern features without being so obvious. This is a displacement boat and I originally drew it up with electric propulsion ( trolling motors ) but could not find any suitable solution for speed and endurance so I have been considering dropping in a 40 hp outboard hidden under the rear deck. The thing that got me to watch your video was the name " Tesla ". I love that guy, his engineering and problem solving skills and creativity, a gift from God. You have some Tesla in you too, I may have a smidge but with no education. When people see my project under construction they always ask if I am an engineer. Pretty funny as I am a 70 year old high school dropout that never built anything. The propulsion system you put together was intriguing and well thought out. Please share with me how that worked out in in your sea trials and if any modifications were required if you would be so kind. One of the best videos I've seen.
You are amazing. Science and practical application together and as an engineering physics graduate which combined both these facets, as an audio nut, and as a lover of fun/potentially explosive projects…and boats…I find this to be my favourite channel ever. Thank you all so much.
Just watched your catamaran build and loved it! I was thinking you were going to add hydrofoils to the build along with a
Sail or two. Maybe next time?
A brilliant mind coupled with amazing hands-on engineering skills. Bravo!
This is so awesome! The quality of your content and the sound science behind every project is truly inspiring. Keep up the good work and thank you for promoting science and engineering
OK, now turn the whole deck into a speaker with an audio exciter. Make it into a true party boat.
Use the best speakers
Ha! That made me giggle
yeah....propulsion due to soundwaves :)
They can use the speakers they made in a previous video.
Then turn up the power and make it a mobile ultrasonic emulsifier.
🎉 I am very glad that you took the plunge 4 years ago to dive in full time with this awesome channel. Your content is very high quality, informative, fun, and well explained. Thank you for everything you and your team do here!
We are, too.
Almost one million subscribers.
Great series. Your "This is a hydrofoil" comment was, I suspect a perfect ending for your audience.
Thanks for your work.
Man, I love this guy. If I had had instructors like this when I was in school, i might have been able to build that hi efficiency lateral generators. I seriously love this guy.
Maybe you could have even made the powered piston pump knuder valve.
if only my school teachers explained things like you do, i may have been an engineer. good luck with the channel.
The information I get by watching this Chanel is really spot on. The explanations are dumbed down enough to give me a full understanding of the principals applicable to the project. Bravo Sir. I'm in!
When I saw the video before watching it, I thought one hour is a little long, maybe I skip this one. After watching it I wonder where that hour went, good job!
"... Supplies..."
My man.
This is so cool. Having "crewed" on a trimaran and owning a small 16 foot mono hull i was impressed by the video content and the ability of the teacher to describe the process of construction. my congratulations! looking forward to seeing progress. bravo!
Thanks guys for your service to humanity, showing us the ways of doing things, we never thought to do. Blessings, and keep us looking forward..
I really like the inclusion of the background science behind the builds!!
Using "Titanic" as a verb. Priceless.
It is difficult to talk about CNN without using Titanic as a verb, as well.
i wish i had you as a teacher in high skool, as we never stop learning i am happy to have you as a teacher now.
Thought the same mate!
Good thing I scrolled down the comments. You said it! (But when I was in school, I would have been distracted by the image in my head of the “fair lady’s perfectly curved shapes”.)
What a great tutorial on unique boat building. Having watched and listened several times, my conclusion is that I hear and learn new information with each repetition. Thank you
I love this guy. He's a freaking genius at pretty much everything.
I was just thinking that this guy pretty much defines "dangerously scary". At first glance he seems like some dude building stuff at home and then you realize he's a casual super genius.
... everything except boat construction
This is one of the best videos I've seen in my entire life.
God I'm so lucky TH-cam recommended this. Best stuff out there
This build is beyond my expertise, but it is informative and I am entertained by your Knowledge and ingenuity.
Thank you for providing this video, I thoroughly enjoyed it.

I remember watching the DIY speaker video, and I couldn't get my head around the quality of the video, vs so few subscribers. I was hooked by the jet engine, and I was glad you were picking up subscribers. I finally had a spare hour to really take in this video, as I love all the engineering details. This channel will continue to pick up more support, just keep up the great work, and newbies will have more to binge on.
This is the third time over several years that I have watched this video. I Think its awesome. also I have watched other videos done by you. Best wishes.
I watched this same video many years ago. I still appreciate all the technical discussion. My interest in buying or building a boat have been renewed. Especially after spending a week in Ocracoke NC last week. Thank you.
Sure!
I would love to see that thing come out of the water on a set of hydrofoils! I really like the content you guys produce, but the videos are often a little anticlimactic. This is an hour long video about building a boat. I would have liked to see it touch the water at some point and see the result of the engineering on the behaviour in the water. I understand this takes a lot of time to cover, but I hope you guys are able to do so in the future.
Gilles Ottervanger I would have liked to have seen some of the testing that was talked about.
So you'd rather a 2 hour video? 3 hour? How long do you need it? Why does it need to have a conclusion.
Thats like telling a car repair channel they better have that car running and on the road in one video, or else I'm a whiny little baby.
If he takes 15 hours of video to build something, so be it. If you don't like it, movie along. The rest of us like it just fine.
@@mikeworkman3593
He could make 2 videos instead of one and include some footage of testing and performance. There is a sense of satisfaction in seeing the success of a lot of hard work. It would help the channel grow.
@@nrml76 um.......
Yeah...
2 videos. That's a fantastic idea.
Are you somehow suggesting he will never make another video?
@@mikeworkman3593 Relax man. This stuff he said is clearly meant to be constructive. A concept you don't seem to be familiar with.

I love everything about this channel... there’s nothing quite like listening to a polymath to inflate one’s sense of intelligence by proximity, lol! Keep up the incredible videos and i’ll be watching with you all the way...
Link Age two things: a polymath is, by definition, someone of wide knowledge or interests, and judging from the breadth of topics this channels discusses I'd classify as being wide in their knowledge AND interests... It is NOT an indicator of one's level of intelligence or education as you seem to belive; someone's age or education level is not indicative of their ability to be a polymath. Shame on you for trying to reduce someone's passion for imparting knowledge into some kind of gatekeeping competition of intellect bullshit... Your teachers are ashamed of you, and you've failed at being a decent human being.
