Pedal Powered PVC Pipe Catamaran with Ducks

gosexman's shared video file.

[@simonflr]

Excellent! By far the most professional build I have seen on KZbin...

[@josephsexton1566]

I actually launched the boat last year and did a couple miles before the drive failed. It moves quite nicely. That prop works best at low rpm. I didn't make it up. I researched it . It also has twin rudders and turns like any other boat.

[@OK55OK55OK]

Yeh, that's quite a project you've finished!! I like it!! the only thing I see that should be changed is the way the rudders work. I'm sure you went to great extremes making them move so easily that you can't even feel it.....BUT, it needs to hold wherever you put it. If you want to turn left, go straight, or whatever, you want the boat to steer itself. That's the key, that it steers itself. You just make adjustments to the direction! Great Job man!! You should answer some questions below!!!

[@laurabong]

Floats great! Pedal broke off during sea trial. Building another boat now so this one will have to wait. See that video on the gosexman channel. It is called Rescue Minor.

[@WorldStove]

stupendeous! can't wait to see the sea trials! nice touch of class with your bow design.

[@BertieW0oster]

Awesome boat, I like the ducks on the front too!

[@30CalCoreLokt]

I was kinda disapointed with the back of the PVC pipe wasnt the tails of the ducks lol GREAT BUILD!

[@powerskurf]

Oh I love the drive mechanism congratulations on a lovely thing.

[@RobbsHomemadeLife]

i AM IMPRESSED, YOU HAD ME AT THE DUCKS.

[@thepoweroftheopenheart4110]

Love the peddle drive !! I would love to know more about how you built the peddle drive gear set up or do you have one to sell? I build wood kayaks and want to peddle drive them. Thank you Doug Powell

[@JosephMelia]

I'ld love to see it working,very nicely done..

[@gosexman]

I hope to answer some of your questions. It's 8" PVC pipe by ten feet long. It easily carried my weight at 160 lbs. On the test drive a pedal broke off and I limped back to the dock. I dropped my cell phone in the water when I launched the boat and subsequently had a fight with them camera man (wife) over the lost phone. (She doesn't understand the concept of "it's insured"). So there is no video! The boat went into storage while I built my next boat, a twenty foot center console with inboard diesel. Watch the videos of" Building Rescue Minor" on the gosexman channel. Sorry I don't have more pictures of the drive mechanism. It's home made with gears and chain. The model airplane propeller is the proper choice for such low RPMs. Boat propellers are designed for thousands of RPMs. I hope to relaunch this summer 2014. I must redesign the chair. The angle is wrong for incumbent pedaling. I may add a sail or a kite for fun.

[@joeselaus332]

gosexman Can you give me more information on The model airplane propeller? What part number, were you can get it, ect and maybe the gars and chain. What is the ratio of the drive?

[@qayaqbuilder]

I imagine that it would sit loud in the water because of the weight of the PVC, even if it is hollow. Also the small propellers can't afford optimum propulsion. I'd suggest wider blades.

[@rickchubka6772]

you are totally fantastic man. go ! go ! go !

[@gastank43]

cause it's pedal powered and in case you haven't noticed people in wheelchairs usually got sort of a problem with anything where their feet would cause the propulsion.

[@charcoal777]

That looks heavy

[@joeblowjohnny2297]

Awesome video ! I don't see a water ride test boss ?

[@Metal-Possum]

A word of advice, you want some means of draining that PVC pipe... Although it may be 100% sealed, PVC is NOT 100% water proof, and it's easier to get some in there than it is to get some out..

[@TheIsmaelIsaac]

well done and I am sure you can have it runinng

[@melvincolvin7123]

How did you attach the wood boards to the PCV pipes? It looks like you bolted them down. I wanted to see if it is air tight, so it will give me some idea on how to attach a floor to the pontoons.

[@TheIsmaelIsaac]

+Melvin Colvin .. I really don't know if you can avoid the board thing by simply making T joints to attach 6 or 8" PCV pipes to go across the two 10" pipes.

[@Spirit612]

Did you change out the prop and use an actual boat prop: the R/C airplane prop might work marginally but is inefficient in the water and a trolling motor prop will give you better speed and control and take up less space on the bottom.

[@MRrailaway]

great job!!!!! I think I'm gonna make something like that 2

[@AClarke2007]

Just an idea: what about using the pipe itself (with a simple flap valve inside) to suck water in at the front and push it out the back? [not the pipe used for the floats of course].

[@uxobob1]

I don't know if you answered the other guy but,. Can you please give more detailed info on the drivetrain gearing (sizes and where you got it). Im doing a similar project and have been looking at the same gearing and propeller setup. Thank you

[@bengibson4932]

[@tolgabali1]

Perneyi nasıl yaptın? Onu yapma videosu var mı?

[@MitchHeil]

Do you have any more pictures of how you made the pedals and the gearing for the prop? I have a kayak with a center hatch that is exposed to the water and I want to see if I can make a pedal system that can easily drop in and out of that hatch. It wouldn't be nearly as long as yours. Maybe 18" or so from the center of the pedals to the center of the prop.

[@andre_putter]

I like what i see. You did a great job with the boat. I got just one question. What happens when you run out of fuel, not the boat you? Just joking. I got plans to build one using wood, but that seems a lot of work. What you did here is a great way. I really, really like!!!!!

[@BreaksFast]

That's a lot of money for a pedal powered boat!

[@chefslot]

could you tell me how much it weighs as this is a big factor in what i'm looking for?

[@davidgriggs3967]

I'm no engineer but that prop looks a little small to move a couple of hundred kilos of hull around and the prop should be right at the rear otherwise you will need 4 football fields to turn it around, nice try though.

[@farisghanma735]

The invention should be called Bateau de la Canard

[@roydesignedthat]

Any one building a one of a kind project like yours should be proud! I especially liked the steering system and OK the "Ducks"! Well done! Have a look at "Houseboat by Roy Schreyer" on KZbin and tell me what you think of my project. More people need to Create! Good Work! Roy

[@anthonywhitehouse2295]

i would love to know more about the pedal drive please

[@adjumakaru]

love that beat

[@amphidory7600]

did you ever launch her? would love to see this awesome boat in action

[@chrishuss211]

Do you happen to have video of it in the water?

[@MrHappychimpy]

It sank before they could turn the camera on.

[@parallelburrito]

Haha...thought you were the OP. All that good work.

[@vicflocay]

Good work, put a sail and you will go fast.

[@cosguy]

What did you use for the transmission (miter?) gears? Salvage? New?

[@wemel007]

we want a vid when it's on the water!! :)

[@ccccen]

where about you bought the pvc with that diameter, 20'' or so?

[@ronaldhotboy]

Freakin awesome!

[@nialpmatk04]

would you happen to have pics of how you put together your drive system?

[@Gershwinwoodcraft]

What is the diameter of the pipes? 4", 8", 10"???

[@adrianlumakang4756]

can i but6 that thing im in a phillipines i like your work very good

[@checo1er]

where did you get the metal brackets

[@tibespescador1251]

oi me passa detalhes destas pedaleiras por favor

[@mickberry9991]

why spend all that time fabricating it just to bolt a lawn chair on it?

[@terraria103]

Very good design

[@watahyahknow]

how did the propeller worked and did you use an airprop from a model airplane ?

[@gosexman]

watahyahknow

[@gosexman]

watahyahknow Yes it is a model airplane propeller and it worked fine. They work great at low rpms

[@DJHernZ]

How did you to the propeller? :)

[@mindfreak001009]

hi there..can i know where to buy the drive mechanism of you pontoon? i'm planning to have one like that for my upcoming vacation in Philippines pls help me find one thanks..nice project indeed!

[@skippy10776]

is that prop big enough???

[@fordmustang500kr]

did it work?

[@loansharky]

Does it float?

[@wtfchanneltomake]

dead angle grinder parts works...

[@AAAAAAACCCCCCCEEEEE]

what size pvc is that?

[@brownskidmarks]

love the seat....lol

[@PrinceKlutz]

Great vid. Too bad about the phone. I'm designing something similar, but different, using a twisted chain drive, tho.

[@curtishaughton2105]

any idea what size pvc pipe?

[@ihoppoet]

Do you have a build video of the drive train

[@gosexman]

No, I actually disassembled it recently. Going to try something else. I put way to much time and money into a prototype.

[@robertszel8048]

Hi Muddy Anchor,I have only one question for you: How much the weight of the 8'' and 10 feet long PVC pipe?((((I'm planning to built a rebelcat5 and looking for the perfect pipe. More cubic centimeter but less weight. The best pipe what I've found is about 73 kg and 0,56 cubicmeter, but I'm sure that there's better somewhere. )))))Rgds

[@gosexman]

Hi Robert, I used schedule 40 PVC pipe which is quite thick and pretty heavy. I'm not sure what the weight is. If I did it again I would look for a thinner walled pipe.

[@robertszel8048]

Sorry, but what means "schedule 40" exactly? Diameter or another? I'm living in Hungary may be our terminus technicus are differ than yours.

[@jamesthe-doctor8981]

Róbert Szél "schedule 40" PVC has a much thicker wall and is much heavier then the thinner PVC Pipe (class 200.) Schedule 80 is even thicker and heavier. I'll list the wall thicknesses and pressure ratings (in psi) of the three types of PVC pipe below. All three examples are 1" diameter pipes... Sched 80: 0.179" (630) Sched 40: 0.133" (450) Class 200: 0.63" (200)

[@bencarter96]

i like the transmission and rudder operation but you need to get your self a really bigg boat prop not a what looks to be rc plane prop (there no good in water very inefficient)

[@jonathantamm9202]

They are very efficient they are used in all the human powered speed records the same APC 18 '' they work well on electric outboards as well low speed high torque. Better to push a large quantity of water a bit faster than the boat than a small quantity at high speed and create lots of turbulence wasting energy. look at the human powered aircraft and the modern large diameter geared high bypass jet engines.

[@Salty_reviews]

APC, rc plane prop? What size?

[@thewildthings101]

How much do you think it cost you to build?

[@itsmePassportBro]

$4253

[@garygrasser8353]

hahhaaha go on a diet,,,,,,i think with a little more thought it will work,but I'm at 150,,hell at least he's doing something,,,and thanks ric,,i will have a beer ,,have a good one bud,,

[@DIEGAN100]

Nice Boat. ¿ PLANS?

[@VancouverCanucksRock]

What's this built for? A 60 lb child?

[@mercenario798]

PARABÉNS!

[@Dwarfvader9000]

What did you seal off the pipes with?

[@gosexman]

Fiberglass and epoxy. You have to scratch up the pvc surface pretty good to get it to adhere

[@Dwarfvader9000]

thanks

[@paulodaytenko5562]

cara isso é ótimo

[@1liltigerette]

Pretty cool.. but why not go ahead and finish deck it--so you have more room on it.... but sweet.. i like.

[@roydesignedthat]

Love the drive and steering systems and OK the ducks. Check out my design at "Houseboat by Roy Schreyer" and Let me know what you think! Thanks. Roy.

[@vimeel4420]

the propeller must be a bug

[@qayaqbuilder]

I meant to say "sit low in the water."

[@stephenbell8284]

Is that a water prop?

[@jonathantamm9202]

APC model aircraft propeller .

[@lunaticcatamaran7666]

genius

[@fontieproducoes4294]

oi me chamo Jaime sou de CTBA por gentileza voce poderia me informar quais são as pessas que estão dentro do cano de 40´´ ou de 50´´ do sistema do pedal e quais medidas elas tem? a epor gentilesa vc fez selado ou lacrado a parte onde vai a corrente? tenho um canal de pesca se quiser pode deichar a resposta la jaimeprofishing email; minhoedrek@gmail,com obrigado.até aguardo resposta até.

[@mazdarx7887]

Don't understand why people waste their time and Money on PVC pontoons. Look around lots of catamaran sail boats around , dirt cheap some free . Start with good floats, then put your silly ideas on that

[@gosexman]

Mazda rx7 It cost a whopping $100 for the PVC. It floats good enough. Its the adventure of designing something youself and you don't have to get rid of all the left over junk that someone else was stuck with

[@MsNailgun]

It is their time and money to waste however they want.. I love building my own things regardless of cost.

[@nemo1987b]

not my type of boot and the music was kind of seventies bad porn film music

[@synthesizer301]

kut zooi

[@cosguy]

What did you use for the transmission (miter?) gears? Salvage? New?

[@gosexman]

+pushtrailer they are new miter gears
