The Tesla Catamaran! 

1 hour ago I didn't even know I wanted to build a boat.

Tech Ingredients in 5 years time - 'how to build your own space station' lol

If this guy was a professor, he would be the one whose class is always fully booked. Great presenter

You have an impressive ability to provide detailed explanations without becoming tedious. Your channel is amazing and I love it

Who else want to see this amazing hydrofoil in action?

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. ;)

The amount of knowledge / technical knowhow on this channel is absolutely absurd. If this was a part time level of quality and in depth information, what is full time going to be like?

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 want to be just like the main presenter when I grow up

I want to see this catamaran perform on the water.

56:48 I imagined Smarter Everyday suddenly appearing, Kool-Aid guy style saying "DID SOMEONE SAY LAMINAR FLOW?"

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 :-)

I'd really like to see this project actually on the water- That is the real test... For the FUTURE?

Love the mix of mediums, science, chemistry, engineering, electronics, woodworking, metalworking. Nothing is too far away from the abilities or cost of the average person with a little drive, time, and patience. Keep up the great work!

"Engage the magnetohydrodynamic drive."

I really like the videos you produce. I'm a former engineer and sailor who appreciates your projects as well as your technical explanations. Sometimes it's good to relearn the theory as well as the practical applications and fun that science provides.

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.

"This is a hydrofoil...You see why you might want to subscribe?" Well I can't argue with that.

"... Supplies..." My man.

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.

Love the way he explains everything so clearly, including mistakes.

"Laminar flow" *Destin wants to know your location.*

"This is a hydrofoil" I came for the pontoon boat, I'm staying for the hydrofoil!

Watching this was really fun. Reminds me of some of my excellent engineering professors from way to many years ago. I am hooked!

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...

"It's probably over-built." HaHa

Let's see some of the tests , I'm very interested in this design but want to see it in action!

Love those timeless topics that just keep on giving, days, weeks, and years later. Thank you sir!

This guy is like the modern Mr. Rogers of science

"If you can give us a comment" Who knew that spam would be considered helpful one day :D All joking aside though, I really love your channel! You seem extremely intelligent and knowledgeable, and that's getting rarer every day...

This is the best I have found thus far. This is what engineering is about: from science to technology to practical applications. Thank you so, so much!

Man, this makes me feel like I could build a boat in my garage!.. Once I get a garage... 😆

I like how the science behind everything is detailed enough to be specific and useful but brought down to a level where a basic enthusiast can still fallow along and understand thankyou

When I saw those flat-bottomed hulls I immediately thought, "He's gonna make a hydrofoil."

Yo, where's that hydrofoil video!? lol... I want to see more of this boat!

This is the catamaran video I referred to in another comment. Very informative. 🎉 good luck 👍 with growing your RU-vid channel. Scottie

I'm just here to leave a like and a comment. I hope you can swim. 👍👍

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.

OK, now turn the whole deck into a speaker with an audio exciter. Make it into a true party boat.

You remind me of my physics Prof back in 1969 at Clairemont school (Ridgemont High) thank you!

"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

"This is a hydrofoil" man you really know how to make me excited :D Really love your channel, I've learned so many things and got inspired so much by you for my own projects (even though my progress is much slower), that I think you really earned some sweet sweet patreon love from me :) (P.S. next year or so Fischerspindle will come out with a 500.000 RPM electric micro turbo compressor. Would be nice to see it in action in your hands before I chain it up for some kind of electric fun rocket engine ;) )

This dude even goes into a technical deep dive of the youtube algorithm, that's why we sub to this channel.

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.

I am an electronic engineer and listening to you explaining all those physics/engineering concepts I had no idea about, in such a clear way, was amazing... How to put it... seriously... amazing. C'mon. Seriously. Thank you!! Amazing... geez!

The science teacher I wish I had earlier in life. I'd be much smarter now.

Boat is missing a jet engine and vertical sails that fold out into wings

This GUY is a Fucking GENIUS ❗ Thank God he is AMERICAN 🇺🇸

I really laughed when you said "this is a hydrofoil, might want to stick around" hahaha

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

This channel has the potential to be life changing. I might have become an engineer if I had encountered this at the right time.

Great project. Thank you for presenting. 👍

Just remember, the slower you go, the more "supplies" you will need. Cheers.

I love how wide, how all over, and how random of tech content you post.

I really hope this channels grows to tens of millions so that I can watch these videos 3 times a week at least!

Awesome work!!! You answers questions that I didn't even know I needed to know!!! Thank you & God Bless you and your family

Absolute love this, and the ending.. ."This, now this is a hydro foil" :D Can't wait for next update! :-)

Next episode: Hydrofoils! And the episode after that: Supercavitating hulls!

Can’t wait to see the hydrofoil in action.

This is an amazingly informative video! I was very impressed, mostly because while I already knew most of this information, I don't remember every hearing everything explained so succinctly, clearly and with exceptional examples! Very well done! Their channel is a must have subscription for anyone interested in Tech Ingredients!

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!

You should be a teacher. Explaining how to actually use maths.

When can we expect the sequel to be posted?

I have thought about building a boat from time to time but the time of build and other logistics made think twice before attempting,but now thanks to you I can see project at the end of the tunnel. I really appreciate your presentation of the engineering principles involved in projects thanks again.Sincerely Bruce Foster

"This is a hydrofoil..." Best cliffhanger ever!

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!

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!

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..

Using "Titanic" as a verb. Priceless.

"hey, i like this content"

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

The asymmetric thruse idea is great for the twin propellors. Should give it quite a tight turning circle. Do you have a trim idea proposed for the boat? not every motor is made the same, so you'll need to trim the stronger one back in power so the boat doesn't yaw slightly in one direction.

When can we see it in action? 😁

I love this channel it's like 'Popular Mechanics' for the modern day.

Me: Can I just wrap my brain around the cool speakers you make? This channel: No. HYDROFOIL!!!

One of the most under rated channels on RU-vid.

He's so brilliant that im surprised the lights in his garage don't dim when he enters.

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.

This was amazing! Makes me really want to build my personal boat.

What a fantastic speaker and educator. This is exactly the type of video I was looking for a first time boat build. Thank you!!

"What would you do if you didn't have to work?" My answer is projects like the ones shown on this channel.

"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.

Absolutely priceless as I'm looking at building a boat too! *Did anybody catch his exact fiberglassing schedule?* It looks like darken wood, and one layer 6oz S glass then paint as mentioned. Is it just one layer of glass? Is it inside and outside like that? Or just glass the outside and epoxy the inside to water proof it? Was it Raka or West Marine? I'm excited to continue to do a lot of these projects (often scaled down) with students!

I'm a simple engineer: I see a Tesla-module - I give a like.

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!

Where’s that hydrofoil guys! The boat looks amazing I want to see it fly.

I'm curious how well this would sail with solar panels...

Didn't realize I was watching for a hour.

When he started talking at the end I looked at the time and like holy shit I just watched an hour long video about how to build a boat... I already own a boat! Still a great video tho.

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!

Thanks for giving me a reason to stay up late so I could finish lubricating my old craftsman belt sander. It was squealing so badly that I couldn’t use it anymore. Oh, yeah…I also wanted to thank you for your videos on panel speakers. I build a couple of pairs and with some tweaking and the addition of a powered subwoofer and a repurposed car stereo head unit I finally have a sound system that I can use in my shop without worrying about sawdust getting everywhere. The clarity is amazing. I tested them with a lossless copy of The Wall. I was so blown away by all of the “new” sounds that presented themselves that I told my wife to keep our son inside and proceeded to unpack my bong, get stoned to the bejeezus and kicked back and listened to the entire album uninterrupted. It’s been a long time. Thanks.

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!

Really like how you break down topics in easy to understand bits.. I actually feel a bit smarter each time I watch your videos

but where is the catamaran test, I wanted to see it launched...(:(:(:

Here's one for the all go rythem!

I've got to say you are the most succinct and eloquent teacher I have ever heard speak.

"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 love how the technical considerations are explained quite deeply rather than brushing over them just to keep a video short. Thanks very much!

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.

Started watching for your audio builds and distillations, but have been enjoying the other content as well.
