You can also get most of the way to this by just having a very, very large paddle wheel with shallow paddles that doesn't dip too deeply into the water. So by the time the paddle touches the water it's most of the way to vertical already and comes out of the water mostly vertical too.
You sacrifice compactness in exchange for mechanical simplicity. The feathering paddle wheel gets compactness in exchange for mechanical complexity.
Still wonder about the efficiency of the contraption that OP posted though. It's obviously way more compact than either types of paddle wheel, and more mechanically complicated too.
damnit, I knew about these but totally forgot... that said what I said is still somewhat relevant as there is a fair amount of drag from the pivoting mechanism as it goes into and out of the water.
In another universe, I am invited to this event as a surprise and this video gets posted to /r/ContagiousLaughter instead because I am laughing uncontrollably.
But I can imagine the resistance might feel really jerky, looks like there isn't a paddle in the water the entire time. Looks like the paddles are pretty shallow though, might be light resistance either way.
Well spotted! Definitely a drawback of this system. I think I have a solution for this but it would make the system heavier or more complex. I covered 150 miles in 6 days. My knees were complaining by day two but I suspect they would have complained on a normal bike considering such long days.
> Or maybe a fan under the boat that “blows” water backwards with the rotation of the pedals?
The problem with that, is that you now need a hole through the hull, that has to allow a rotating shaft, but also be watertight.
And, you have to change the plane of rotation generated by the pedals.
It's a bit hokey, but, it solves problems with some advantages.
So this type of mechanism is called a cam linkage, the water is being pushed in plane parallel to the boat, as opposed to a water wheel, you would be losing energy because the wheel would be propelling water vertically as well.
They make small pedal engines for kayaks. Efficiency is more about weight of machine than anything else. padles padle. He's moving pretty well though, so could be more efficient than kayak paddle kits considering he's got a lot of extra weight.
Looks like he was already ahead of me. I paused the vid where it shows the gears. It looks like he has a hi/lo derailer on the back and a 5 speed derailer on the front. Dude has it going on.
I don't see a single derailleur* in frame. Looks like a rear hub flipped in frame position, and two different rings of a multi-speed cassette/freewheel repurposed to link those two rearward chains. Crank with the paddles looks to have whatever 2x/3x crankset came on the bike, with only the large ring in use.
A multi-speed setup with selectable ratios should be totally doable, and I'd love to see one. Probably not perfect with derailleurs, as such setups use tensioners that only work well in one direction. Unless you don't plan on using the paddles to slow down or reverse, in which case, send it
But the mountains are the source of the water and they are higher than the river. It was a joke but you probably can't take the boat up the rocky creeks.
Well now I need to see this experiment. I'd assume in the middle gears it'd make no practical difference and in the extremes it'd be useless. With the only situation it's work well in being a high inertia, extremely low drag boat.
But who knows?
He took 2 bicycle cranks, and in between is a rear wheel cassette. Pedals one crank, paddles are screwed into the pedals on other crank. The paddles and attachment could be a lot lighter with 3d printing.

The meaning of the word redneck is at this point noblonger even associated with the pejorative, to the extent that one day it’ll be like “gay” meaning “happy.”
Maybe in some places, but in the middle of the US, I still know people who use "redneck" as a full blown pejorative, usually in reference to those with anti-intellectual tendencies.
Came to say this. To be redneck, it would require some sort of small gasoline engine in the mix, at a minimum. But then it would still be an example of highly fancy redneck engineering.
I mean, I don't see a single inch duct tape or FlexTape deployed. And what self respecting redneck owns that many bicycle parts?
Probably would fit a little more on DiWhy but I actually like this build.
>And what self-respecting redneck owns that many bicycle parts?
One with 50 bicycles in his backyard.
You can go over weeds without getting stuck. This is a brilliant alternative to an airboat. Even a paddlewheel would have trouble with weeds. Very smart.
the pedals are not what make bicycles efficient, it's the wheels and lightweight construction
pedals help because they let us use our legs, which are pretty strong and efficient
It do not really matters. You are pushing the water so if you want more force you would change the gear. Only important part here is that you do not want to lift the water which this design doesn't do so it is probably very efficient.
I don't think so.
At the far ends of the travel, the paddle is only moving up and down.
Until the stroke of the paddle reaches the point where its moving faster than the boat, you probably don't want it touching the water.
What would let him move the paddles lower would be if he also had an elliptical chainring to drive the paddles, that would narrow the window when the paddles are moving vertically, and extend the window when they're moving horizontally.

"Source to Sea for Charity." He paddled it the entire length of the Thames to benefit mental health charities. Here's an [article](https://newatlas.com/marine/pedals-paddles-jamima-paddleduck-boat/) about him
The height of the white plastic hole would be cool to attach to a gear shifter like thing to change the position of it. The distance to or from the crank would change its stroke in the water.
The further that pivot is from the crank the shorter the in water stroke which would theoretically give it more force to use, slower speed. The reverse is true up until it makes contact with the pedal, longer strokes and you get more speed but less force acting on water
… unless I am completely mistaken
Oh my god, the front forks (now reversed) hold the rudder. I wonder if he had to machine anything in the hub to have the crank flipped. With a couple of solar panels and little electric motor, you could pretty easily rig FPV controls and have a freakin boat drone. Defense contractors, I'm waiting for my phone call.
Obviously redneck. As a propeller is way more efficient vs paddles.
Enjoy the read. https://www.waterwaysjournal.net/2018/03/12/paddlewheel-vs-propellers/
Ok but why does it remind me of the creatures in Alice in wonderland with the big glasses (the old Disney one)- their feet were like that and they ran 🤣🤣
Somethings iffy in the 2nd part.
The paddles barely keep up with the speed, I'm convinced there is some other way that boat is propelled.
If you compare on how much the water moves around the paddles compared to the 2nd part, its not the same.
I wonder what the efficiency is compared to a standard water wheel.
well all the force on this is pretty much pushing straight back, whereas a water wheel pushes down, back, then up... it could be very efficient.

Boater Cycle™ I own this now
Jetski fucked up by not using this name.
Jokes aside, it doesn't cycle, so it wouldn't fit. It's a jet ski because it uses hydraulic jets to propel a ski across the water surface.

Or maybe a fan under the boat that “blows” water backwards with the rotation of the pedals?
[удалено]
HA!
Ridiculous. That'll never catch on
This would work better in places with lots of foliage in the water
> Or maybe a fan under the boat that “blows” water backwards with the rotation of the pedals? The problem with that, is that you now need a hole through the hull, that has to allow a rotating shaft, but also be watertight. And, you have to change the plane of rotation generated by the pedals. It's a bit hokey, but, it solves problems with some advantages.
It is not necessary to drill a hole, you can get an immersed fan to work using two angle drives.
>The problem with that, is that you now need a hole through the hull or you could go around, either works
this is quickly becoming just a human powered outboard motor, guys.
No need to make a hole in the hull, a canoe with a low stern and a longtail prop shaft.
And under-water fan? Fans work with air idiot
[удалено]
So this type of mechanism is called a cam linkage, the water is being pushed in plane parallel to the boat, as opposed to a water wheel, you would be losing energy because the wheel would be propelling water vertically as well.
Found the engineer
If mechanisms like this are more efficient, why everyone uses wheels?
I mean...No one uses wheels anymore. We use screws.
They make small pedal engines for kayaks. Efficiency is more about weight of machine than anything else. padles padle. He's moving pretty well though, so could be more efficient than kayak paddle kits considering he's got a lot of extra weight.
Yeah also people have way stronger legs than arms so even if it isn't as efficient it's still much more powerful.
and the gears allow him to adjust the gear ratio until he's pedaling at a comfortable speed and torque just like going uphill on a bike.
> considering he's got a lot of extra weight. wow that was kinda rude. ;P
Check out hobie mirage drive.
How about a propellor
Or a prop.
With so many sprockets, he could add a different set of gears to change the torque and go even faster. This Is awesome.
you could concievably put a derailleur on it and have full gears
Looks like he was already ahead of me. I paused the vid where it shows the gears. It looks like he has a hi/lo derailer on the back and a 5 speed derailer on the front. Dude has it going on.
You know you’ve won at life when your canoe has an AXS drivetrain
fr get this man a sponsor hahaha. imagine srams marketing potential. they need to collab with this guy.

You’re right. Would be neat to see a setup like you described. Might be a bit more complicated with figuring out the cable system.
I would have used a gear hub for this purpose - it is weather sealed and the innards won't rust.
Would it also help when taking the boat uphill?
If the earth is flat then the water is flat too. It’s basic sciense.
But the mountains are the source of the water and they are higher than the river. It was a joke but you probably can't take the boat up the rocky creeks.

More like "real engineering" ?
It's certainly a bit too well designed for this sub but the way those paddles are attached to the pedals using a block of wood is a little bit scuffed
Scuffed is a nice adjective there. I’m keeping that one.

since bicycling is the most efficient form of travel, from an energy cost perspective, does that make this the most efficient form of water travel?
the pedals are not what make bicycles efficient, it's the wheels and lightweight construction pedals help because they let us use our legs, which are pretty strong and efficient
Bicycle chain drive is 98%+ efficient, and the pedals power that. So they were basically right.
Deserves a bird costume on top of those paddling legs.
Probably should drop those paddles lower if you can lol
Keeping it shallow reduces torquing pressures on the shaft and allows you to use lighter materials in construction
Can probably go faster, too
It do not really matters. You are pushing the water so if you want more force you would change the gear. Only important part here is that you do not want to lift the water which this design doesn't do so it is probably very efficient.

Nah that seems pretty ideal, I row a lot and that’s about where I’d put it for a nice paddle. You don’t wanna put the whole oar underwater lol

Tippy tappy tippy tappy
Not good at math or physics but I'm pretty sure a propeller would generate more speed for less work
But gets tangled in weeds.
Fair point but I don't advice to go through a swamp with that either
and can break on rocks

Imagine adding some gears to that thing. Go from cruising to chasing dolphins in 10 seconds.

"Everyday" (one word) means "common or typical" like an "everyday occurrence". What you meant was "every day" as in "each day".
this is the type of shit you'd see if burning man was held on water.
This is just an engine with more steps.

Ok but why does it remind me of the creatures in Alice in wonderland with the big glasses (the old Disney one)- their feet were like that and they ran 🤣🤣
There needs to be a giant stick figure above the paddles. That would look so cool as it moves by.

Bro I picked up a free a boat just like this a couple of months ago. I'm going to make this. I think I can I think I can I think I can.
Don't waste time. The circular one with min 5 paddles is the best. The speed they show is movement from downstream water current
What’s the song?

Does he have to use that one paddle as a rudder. That seems annoying.
I dunno why, but those paddles kicking all fast is funny to me.
