Boats use knots instead of MPH. I mean, usually. While sailing the bahamas in a 47' Vagabond sailboat, we hit speeds up to 8 MPH. Do you know how fast that is in knots??!! I'll tell you! And give you the fascinating history of how sailors calculated speed back when I was a kid in the 1600's.

@@MaoZedong2225 How can you be sure? AI is getting really good!
@@LyfeUntethered so am i now talking to AI connected to your TH-cam account?
@@MaoZedong2225 It’s impossible to know for certain.
It’s crazy how going over water makes you feel like your going faster.
It TOTALLY does. 8 knots and you're FLYING!
It’s because you can see the water surface next to you pass by without anything obstructing your view, like walking or on a bicycle. However, higher up In an suvs or a bus, the doors/sides block the view of the ground next to us. What we see is farther away making it look like we’re moving slower than we are. How about looking out the window of an airplane at take off vs seemingly crawling from altitude? Have you ever looked at the ground while riding a motorcycle on the highway? 😳 So yah, 6 knots in a sailboat or 26 kn in a speedboat is fast! Don’t fall out! 😆
Depends which boat you are on but sure
Also, Michael Phelps swims at around 4mph... which is an especially brisk walk. We aren't made for the water, so everything feels faster.
you’re
We still call it knots... The good old days of today
Yeah, we use it in the air aswell so
1 knot equals around 2km. So much easier to understand
The good ol'days requires some chained "volunteers" underneath the ship to paddle it.
Too bad, this generation criminalized it. 😢
@@pongangelo2048Yea, what a shame we abolished slavery
@@set7938knot is speed not distance
Let's take a mile which is already not a great unit and divide it into 120 parts cause why not, and then we're going to time it by using 28 seconds as a standard... knots also known as potatoes per bananas.
Lol. It's more than I would have every figured out! I'd be like "We should go faster...."
Wrong.Nautical miles are actually the least nonsensical of old units,because they are equivalent to 1 minute of latitude.
@@naamadossantossilva47361 minute of latitude... So 1/60 of a degree which is 1/360 of the earth's circumference. Yeah buddy you don't understand the convenience of metric if you think that's an argument for it being easy
@@theporcupine9993 It's not about being easy,it's about usefulness for navigation.
@@theporcupine9993yeah..that's much simpler for navigation. it is far easier to make distance calculations with a nautical mile since those use the earth's curvature, and the nautical mile is the standard across the world for marine distance. the nautical mile isn't imperial - in fact it's defined in metric as well
Knots is short for Nautical Mile per hour. A Nautical mile is a minute if arc on the worlds circumference, thus the navigators saying that a minute is as good as a mile. Worldwide navigation is done using degrees, minutes, and seconds (can also be degrees and decimal fractions of degrees) thus the unit of distance is measured using knots since the relationship between minutes and nautical mile is 1:1.
Knots by Hourglass. The Days of Their Lives.
ahh, the good 'ol days... when we watched the hourglass instead of TH-cam...
So ends the days of our lives.
Remember when my mother told me about this show, characters apparently just keep on going or something
Never knew why.

what?
They would also to measure speed throw a log off the boat at the bow and time how long it takes to get to the stern. Thus the logbook was named
The name of the log also spread to the book that these speed measurements were written in.
...Hence, when we need to record things, that record is called a log.
The cliff hanger at the end....😮😂

@@tobybeggs8676 The Blind surfer? Looked him up! He sounds great! I used to do voiceover back in the day.. (old channel: th-cam.com/users/trevorjonesvo)
As i sailor my self, we still use knots for measuring because the nautic system hase been based on that since it’s beginning. So my question is why do you use mph instead of knots?
Great video explaining how the nautical miles system works tho👍😊
It's not my boat. I tried to change it to knots, but couldn't figure it out! You think it would be like 1 obvious button! I was kinda embarassed to show MPH in the video!
Maybe MPH refers to Nautical miles per hour = knots
@@filippo7284Knots uses the symbol kts (sometimes just kt or even kn). MPH is the standard for miles per hour so using it for knots wouldn’t make any sense.
@@filippo7284 but miles and nautical miles are not the same
@@filippo7284mph is always statute miles.
Thanks for all the work you do keeping us up to date in these tumultuous times.
They also write it down in a book to keep track of how fast they've been going. This method of measuring your speed gave the book it's name. We even use the same name today for the book, but for keeping track of varius different things. You've probably heard of a "logbook". Probably related to term if "logging in" as well.
Oooooooh knots. Nautical
Gotta love a good knot
It's the scaly pfp that completely re-contextualizes your comment...
with that pfp, what do you mean by that..?
it was predictable
Uhh
_Bruh, what the f-_ 🤣
They would also put this measurement in what they called, a logbook.
💯
That and many other "things". Anything not totally personal went in that log - only Captains were allowed to bring their wives, so that went down, too 😅
@@LIZZIE-lizzieOK but you're missing the significance here. I'll make my own post on it... The word log as a verb is directly from this physical piece of wood
And it's a log book because it is made from logs?
Yes the log book paper is made from logs, And those come from trees.Trees need carbon dioxide to grow, and thats produced by modern ships.@@valmikabeneteau7229
1/120th of a nautical mile (1852 metres) is about 15.4 metres, not 14.4 metres.
Thanks for the correction. I made a mistake.
The most advanced math anyone would use outside of school in a practical application
Interestingly enough they still used this sort of technique not to long ago. Skipper used to lay telecom cable and running 20x the length of the vessel in piano wire of the back of the ship gave them a much more precise idea of how fast they were moving, especially when they had to know that number with little tolerance for error.
Interesting, since he lays cable on(in) the ground, I would think his SOG Speed over ground would be more useful than through water.
"Watch this video to see if we died "
Cmmon dude , you had a camera and we all know the saying about cameramen !
Cool. Love everything boating. Good trivia to know. Useless but interesting.
Useless but intersting! 😂 Thanks for watching! #themoreyouknow
That's what the word trivia means. A plural derivation of trivial. How's that for trivia?
One more, I'm spamming the better trivia not mentioned. The log readings from those days of knots were kept in "log books". Log referring to the piece of wood they threw overboard. The use of "log book" eventually became more generic as more information was recorded...jump forward some centuries...you LOG into an account online because knots were tied into a rope attached to a LOG. Direct etymological connection.
Learned about this when i was on a sail boat for 4 days for school day and night putting up the sail and going to our sailing stations was fun
What are these measurements. 14.4. 28 seconds absoulty wild
Amazing, transforming an outdated measure to bald eagles per glazed donut
LOL. But this is why we still use knots (besides to eat more donuts, which I encourage) - th-cam.com/users/shorts0hxq8C4tDso
Nope, it is the one US unit that actually makes sense. (as you portray)
Question: why sailors still use old day speed units instead of traditional km/h or miles/ hours nowadays?
It is = to 1 minute of longitude on a map, or 1/60th of a degree.
A nautical mile is about the only one US unit that has a solid base, is logical and is critical when navigating.
(as explained)
For the longest time I wondered how fast was a knot and what was a nautical mile in comparison to a mi/km. Ty! ❤
Glad to help!
Cuz you don’t know how to search the internet?
Because it would be far harder to actually research this topic than to just happen onto a video by chance
I always thought “knots” was just slang for “nautical miles” that’s really cool that there’s an actual method to it!
When sailors had to have freaking PHDs is Mathematica
GREAT INFORMATION ‼️‼️‼️
Glad it was helpful!
Interesting fact to add on. They would take those speeds and put them in a book. They called it the log book and that is why we now log into accounts.
Yep!!
Love sailing
No true sailor would have their KNOTmeter set to anything other than knots. Why? Nautical miles. All marine charts, in fact all maps are in nautical miles. One minute of latitude is one nautical mile, one degree of latitude is 60 nautical mile, so to calculate position on a nautical chart, measured in degrees and minutes of latitude and longitude, via dead reckoning (course, speed, time) it's particularly important to know your speed in knots to be able to calculate, with any measure of accuracy. Knots, or nautical miles per hour, are used because they correspond to nautical charts, and prior to the advent of electronic navigation, and as an important skill in the event of any kind of device failure, allows a mariner to calculate where on earth they are. That is why no true sailor would ever have their knotmeter set to read in anything other than knots.
Absolutely. I was embarrassed it was set to MPH. Not my boat. Tried to set to knots but it’s either broken or just not intuitive. On a plane back to boat now. Will try again! With Google if needed!
Next video idea: Land Nav and do 'clicks' i learned it but have since forgotten
Love the history
This video perfectly explained what I’ve been curious about
Glad to help!
I never knew! Subbed. And a 28sec hr glass. This was the constant standard back then?
Dude, I'm not sure! Others have brought that up and now I have more qustions! Thanks!
We still use knots
yes. yes we do.
Thats the most intresting way of measuring speed I have ever heard of
You know, if someone didn't figure it out for me, I'd never know how fast I was going! 😂 Glad there were math wizards 300 years ago to figure this stuff out!
"and the triangle would kinda hold that in place" jaja so mysterious
Ya, they did the best they could with what they had!
Funny thing is, the most advanced aircraft in the world today still use Knots
How cool is that... 👍🏻🏴☠️
That is some blue ass water.
Ya, I’d never seen anything line it.
@@LyfeUntethered Was that a log line pun? lol
Ha, I wish. Just can't freaking see tiny letters. Or type, apparenlty @@jamie.goodson
Pretty sure most vessels still use knots. Could be wrong though.
As in the unit not the physical rope thing
Yep. They do.
So really useful info that I need to know
Didn't know that history, thanks!
How many inches apart are the knots?
About 567 inches
Where is this place?
It was a ships log not chip log and it was called a log because that's what it was. A wooden log tied to a long piece of thin rope that had knots tied in it a intervals. You dropped the log over the side and counted the knots payed out in a given amount of time, which gave you your speed through the water.
There seem to be differing opinions on that, but I wasn't there, so I can only go by, you know, what google tells me! Thanks for the info.
There is another method involving two sailors, a piece of wood a whistle and a chronometer. First sailor stays at the bow and holds the piece of wood. The other is at stern and has the whistle and the chrono. When he whistle, and starts the chrono, the bow sailor throws the wood abeam in water. When the stern pass the piece of wood floating on water, the stern sailor stops the chrono. Knowing the ship lenght, or more precisely, the distance between the two sailors, it is extremely simple to calculate speed.
At first I thought he said: "they use their nuts to measure speed"
I do. It chafes, but nothing a good lotion can't fix.
Going 10 mph on the ocean feels like 90 on the freeway
Where did u guys take this video?
Wicked interesting.
Its still knots. Its why a Nautical Mile is longer then a Land Mile. Its still used today, in case of a navigation blackout.
So informative
So, is it just a coincidence that Knots sounds like a shortening of Nautical miles?
Maybe? I’m not really sure!
Why are knots still used?
Fun fact, the term "log book" come from writing their speed using the log line
Wow....thanks for sharing.......👍👍
I stayed on a schooner and learned how to use a chip log, never thought I’d ever hear that term again
Did you use a 30 sec hourglass?
@@oldmech619 I can’t remember if we did but I don’t think so, I think we used a pre set mark on the line
@@__OZYMANDIAS__ I presume you learned how to navigate with a sexton. Electronics fail. Besides, sextons are fun!
@@oldmech619 no unless they called it so other than that, it was the zodiac schooner with my class last year on a school “9th grade right of passage trip” so it was more learning about how to coil ropes, man the ship and pilot it ect, not much navigation stuff thought
@@__OZYMANDIAS__ The Zodiac is one of the most iconic schooner afloat. As a kid, I saw an adventurous movie were a schooner was sailing cargo to the small South Pacific islands. Ahhh, the dreams of the young. And you got to live it. I did have 32ft Islander. Nice boat.
And commercial fishermen in Australia still use knotes and measure the notes the same way if el electronics fail

Appreciate it!
How do you measure 28 seconds with an hour glass?
That and pyramids remain life's greatest mysteries... (ie, i have no idea!)
No wonder furries love sailing so much
Wait what? Don't understand the reference?
That's pretty cool. I never knew that.
For the record we use this in aviation, and nobody for sure knows why. Legend has is Chris Columbus was flying through the sky in his ship and the only thing he had on board was the good ole log. Chris Columbus was never a pilot. We do not like knots. Keep knots in the water.
So, you really never really grasped the correlation between Nm's and degrees or minutes?
This might just be the very valid reason aviation embraced the Nm...
The book they wrote the speed in was called the “log book”
This is absolutely knots dude!!!
Incorrect. 14.4 meters is not 1/120th of a Nautical Mile.
Knots are still widely used today! Not just on the sea but also in aviation.
I use knots for personal enjoyment uwu
I use gps but sometimes i like using old fashioned methods, as backup
For no reason, I've always assumed that "knots" was somehow short for "nautical." Nope. Knots was short for knots! Thx!
1 Nauitical mile is also 1/60th of a degree of the Earths circumference at the equator
Yep, and every meridian (latitude).
This speed would be the speed you are making relative to the water, so they wouldn’t be able to use it to accurately measure how long it would take to reach a destination right?
That makes sense! They could guesstimate, but if they didn't know the water speed, ya, it wouldn't be terribly accurate, depending on currents.
They just did not have many other means, it's called "Dead reckoning".
Still struggling with the metric system. 1 Nautical mile is 1,852 meters so 1/120th is 15.433 meters
Ya. Me too.
Damn, you're right! Now I'll have to recalibrate the logline I just made, by moving each knot 1.033 metres to the left. Or is it to the right. Might depend which hemisphere you are in.
@@madbrowndog4887, Nearly 50 years ago the USA passed a "metrification" law, but it was an unfunded mandate so there was no enforcement. However I committed at the time to memorize most of the conversions, a lesson that has since served me well working internationally for the last 24 years, especially as I'm and Instrumentation and control systems engineer and units of measure are my life. In any event the sad bulk of Americans are saddled with dual lablings on most items with the only industry that made "hard conversions" being alcoholic spirits and wine. A 1/2 pint became a slightly smaller 200ml. A pint, a slightly larger 500ml. Liters slightly larger than the quarts they supplanted.
The one nearly identical conversion was the infamous "Fifth" or 4/5ths of a quart, which is almost exactly the 750ml. You find today. However, marketing being what it is you may now find that "Fifth" downsized to 700 ml. Pardon my wayward detour down the path of "Potent Potables" from Jeopardy. I wish you fair winds and following seas, carefully calculating your knots!
Bars so fire he went behind them
What?
...And that is how we got the word "logbook"
Yep!
Wait, so knots aren’t used anymore? (It’s not a rope joke I genuinely thought that way of measuring speed was still being used)
They very much are.
Damn, I can't believe Jeremy Clarkson was actually right
Wait. He explained this? In a car?
@@LyfeUntethered Yeah, in the Toybota, while crossing the English Channel iirc. He had a knotted rope and tried to gauge his speed with it. Didn't work out very well, but he did try it lol
why did you have to put that gd text in the middle of the screen? Why'd you think that was a good idea?
I get it. Annoying. But most shorts are watched with no sound. No text = WAY less views. I guess I could make it a little smaller and lower?
But how'd they get all the knots on the line.. That must have took a long time.. 🤣😂
They hired the dudes that built the pyramids.
But why is a nautical mile different from a regular mile?
Mostly because nautical miles were just too big for land. As one (the original mile) nautical mile is about 1.8km, the mile is also gained by taking the circumference of the earth at the equator (one of the great circle or GC points of the earth) and dividing that by 360 to get one degree. That one degree when travelling is then one mile or 1.8km long
Tried this in my truck.
Now they call me
"Old Three Finger Joe"...
Why does your boat not use knots for the speedometer
Oy....too complicated😮
Why would you ever have MPH displayed on a boat?
is that why they call it knots/nautical miles??
As a furry I can confirm that I also measure knots :3
I was looking for a comment like this
It was predictable
I read somewhere that one knot is a mile and an eighth. Not what was said here. Wonder who's right?
so you're telling me it's an extremely archaic measurement and we could just use GPS to calculate the MPH/KPH
Okay, so I always thought it was something about knots. Then i realized it was probably supposed to be "nauts" as in nautical miles per hour. Now I dont know what to think
It's the knots they tied in the line. But yes, sounds like nautical.
And they recorded those chip log speeds in a logbook!
I just learned this but thought it was cool. 1 knot means that you are traveling 100 feet in one minute. So compared to mph... 1 mile per hour is equal to 5280 feet. If you averaged 1 knot over an hour you would travel 6000 feet.
They really said powers of 10 are lava
Ships Still Use Knots Today.
Absolutely! They just don't use chip logs to figure it out anymore!
Internally screaming eternally
Is there any particular reason, why those relations were so un-handy?
Probalby because they didn't have iPhones? I couldn't have figured it out with what they had. Imagine your a deck hand and the captain says: Here's an hour glass, a piece of wood, and a rope. Go see how fast we're going. 🤣 I'd be like "you got a tape measure? No? How about a yard stick? What? Yards haven't been invented yet? Crap."
Noty point. The ratios of the units could be made quite a bit easier to calculate.
But then again, the US is STILL like that and they seem to think it is easier to stick to that, with it's complicated, error prone, hard to learn system, than switching to what everyone else has already found much more useful.
"Watch this video to see if we died".Wtf! Like....😱🤐🤣🤣
did it work?! 🤣
@@LyfeUntethered I guess it didn't.🤷🤔🤣🤣

1/120.....
Why would you choose 120 as a divider? 128 would have made sense, but 120?
When I was researching it, that number was reported. I should have double checked it but yeah, it’s inaccurate.
@@LyfeUntethered is it 128 though?
That would be the rope halved 7 times.
And thank you for clarifying it
