Picture of filming boat
This is a filming - cycling - sailing - rowing - sleeping gipsy device.
For 1 person, < 3 m, <100kg, towable by bike, independent (the bike fits in the boat), 4m2 sail in 2 parts, stainless-steel structure, plywood, fiber-glass and epoxy, carbon mast, nylon rope shock absorber, inflatable rubber floater, sleeping facility, steady cam, to make crazy films ... not secure ! ... hehehe ! cesar

Step 1: Long presentation ...

Picture of long presentation ...
This instructable is going to be long .. in order to be instructable ...
First, the objective of this entire construction was to make this film

Watch this film in much better quality on vimeo here

I edited this film in 2 very different ways (very fast transparent / very quick synchopated) to study our perception of space in time, elasticity and fragmentation, emotional ways of processing information, a film of space and without hero : an imersive objective expressionist road movie.

The boat was a part of a , long process, the boat, the trip, the film and finaly an essay called " troubles in space perception " (french).

Step 2: Previous experiments

Picture of previous experiments
I didn't start from scratch, to have this idea I made before :
1) in 2002, a simple trailer for bike with stainless steel frame and plywood, very handy with BMX wheels, can carry up to 200kg !!!
2) in 2003, a 2 persons 10�£, built in a day for grafitti in London. Thanks to Tom the Irish homeless who helped me collect diz industrial wastes in Hackney Wick. HACKNEY REPRAZENT

can you include a pic of bike in boat
MartijnD1 year ago
Nice project! Suggestion to your camera fixture, as every movement of the boat will be recorded, I would use a self balancing fixture, have an "arm" with the camera mounting foot 5cm above the bearings and under the bearings a length of 25cm with on the end a counter weight as heavy as the camera or more. The bearing you can find in "auto leveling lasers for on the construction site. most of those have 2 sets of bearings 90° rotated, so always leveled up to the maximum position of contact between parts. This way the videos you make will remain leveled.

WOOHOO!!! I love it!
this is all great grand and wonderful, but after all is said and done, could'nt you've bought a small inflatable raft and carried it in a backpack too?
this is better that a inflatable raft rather because you can go through worse stuff in this while still staying afloat especially through rocky spots at least with PVC floats
cesar harada (author)  kyle brinkerhoff4 years ago
Sure, you can also take a surfboard, a skateboard, just a backpack and a swimsuit, or maybe just naked with a knife, whatever you like :)
For sailing with - 2 sails - you need a good mast, you can do telescopic, but it was still 2 x 2m long tube in my case (second-hand windsurf mast), doesn't really fit in a backpack + 2 long wooden rows. Inflatable kayaks are great (not really sea-worthy though), but you can't really fit a bike inside them (my bike is a normal bike, not even foldable, I take off pedals and front wheel). Inflatable raft are great, I love them. I guess you talk about a really big backpack. You can take a small inflatable raft in you backpack and row down rivers, it is just a totally different type of vehicle, and different journeys. Do it :)

i would add elctric motors and make it float with out the outriggers

overall i really liked this 'ible and you said that you need funding somewhere in there

"...a sticker of instructable on the sail (next time, sponsor me pleeeeaaaaassse !!!!!) "

you should really check out this site

two good expaples(sry cant spell and its 1230 am)

and more like what your doing

overall for you i give a 5 star*

cesar harada (author)  hg3414 years ago
Hey, thanks for suggestions and the 5* !
I really love Kickstarter. Sometimes I want to make a serie of this boat - I mean make it much better, cheaper, lighter, greener materials, and manufacture it. It was really great traveling with this vehicle. I guess I will manufacture this when the price of oil peaks again, hehehehe
deqwer4 years ago
em i think your inflatable rubber balloon can change into PVC and between the space and the boat you can put a net and carry your stuff on it

or maybe just forget it
cesar harada (author)  deqwer4 years ago
I agree :) Will do next version! Thanks!
I envy your creativity! :)

what happens if your bike comes undone and slowly falls to the depths (or is that possible?)
cesar harada (author)  hguvg4 years ago
Hey, thanks for comment.
On the bike side :
and on the boat side :
it can handle a few tons of dynamic (typically a car towing a caravan) the connexion is way stronger than the bike or the boat itself. It is hard to disconnect involuntarily the bike from the boat, it is a strong mechanical connexion, it also has a safety pin.

But let's say - everything is possible - by mistake I undo the connexion : the bike will drawn yes. What I did is I injected insulation foam in the frame to protect from corrosion and I put thick grease on all mechanical parts, but there isn't enough air trapped in the bike frame + wheels to keep it afloat. You would need extra flotation for the bike, could be as simple as a triangular bread of foam in the frame :)
How much does this thing weigh total?
cesar harada (author)  Sponzyparadox4 years ago
In total ... hum hum ... too heavy ! About 65kg empty, that's about 100 kg loaded (including drinking water ~10l), and when you get heavy rain it can be up to 120kg! So, yes : I am working on a lighter version. Good thing about this heavy (with Stainless steel structure + super thick plywood, iknow it is over-engineered) is that I had an accident with a truck, and the truck was sooo damaged - the boat was perfectly fine! HAHAHA
I was going to say that looks pretty hard to drag around by bike, Perhaps some aluminium for the frame and lexan for the ply?

if somebody made a movie on it it would be called caption of the junkabien! lol
im not making fun of your boat because i really like it :)
marlonboro5 years ago
Parabéns!!!! Muito louco!!!!!
Im halfway through designing one of these well a variation of one but im making it so theres a motor running a propeller hopefully
sc6chuck96 years ago
I've had an idea almost the same except I'd like a 4 wheeler to pull a boat with and when you get to a lake or pond you put the 4 wheeler in the boat to power it with. Just a thought
cesar harada (author)  sc6chuck96 years ago
I think the 4 wheeler is a very good idea. I have this rough idea : would be nice to have a 4 wheeler, but if the 2 pairs of wheels remain parrallel, it is going to be hard to "drive - sail" it, so I thought "maybe it would be good to have a 4x4, or even a catepillar" (!!!). Some river boat like this one
if the wheels were independently controlled, could make a 180 degrees rotation, how nice!
I also drew a 3d mock-up of a "caterpillar boat" in reference to the insect, not the military vehicle : {image}
you can also have the sketchup 3D file here [400kb]
And you might find this funny
where it is not too deep ! If you move on and actualy build it, let me know, I am very interested, and if there is anything I can help with, let me know! Good luck!

Thats very elaborate... It seems like a great idea, but for whoever makes it - keep it foolproof because elaborate things tend to break when least expected (I have first hand experience) Anyway it really is a great concept!
cesar harada (author)  mweston6 years ago
I do totally agree. This vehicle tend to be too complex to - draw - provide expensive materials to build it - require too much carpentry, welding, mecanic... knowledge - too heavy - not environmentaly friendly ... That's why we need an instructable to explain it ... I hope it wasnt. When you look at totora boats (images below), you see that you can have an ancient "primitive" technic, with lightweight, few materials, ecological and straightforward to understand ... so yeah, there is a lot of work to simplify it! I'll work on that. Thanks for your comment.
Still a grreat overall idea anyway (could easily be built upon)
246810126 years ago
it would be cool if you could put the bike on the boat and attach it so when you peddle it would turn a propeller in the water and push you forward nice instructable
I was thinking the same thing
mweston6 years ago
Fancy, next challenge - cross country

Maybe I overshot on that one

thats a boat id love to make.
cesar harada (author)  derttiej6 years ago
Please do! It was an extremely very very fun project! And if you want, share your experience, it changed my life. Good luck.

Now here is a man who REALLY hates to walk!! :)
Wow. thats fantastic.

Great job

cesar harada (author)  I_am_Canadian6 years ago
Thanks a lot !
That was 3 years ago now.
I just started a new project, It's going to be a long process, but I'd love to publish it's development as an on-going experiment on Instructables (maybe as forum post later):
the text can sound a bit ambitious, i want (and what else can I do but) start little...
So thanks for your encouraging and best luck for your projects too!!!
That sounds awesome! i love sailing. btw, do you actually live on the gypsy boat? Just thought id ask. anyway, im looking forward to the sailing thingy!

Can you fit in the bed.
cesar harada (author)  Hawaii000007 years ago
yes i fit just right, i am 180cm high. I had to build a custom sleeping bag because i wanted to keep the mast at night, so i tend to sleep the mast between the legs, it is a bit uncomfortable and you loose body warmth by separating the legs ... At the same time, the legs are "hidden" under, hit tend to remain in there and so does wetness. I dreamt to host my girlfriend for some nights, but ... it is small to be honnest ... unfortunately heheh !

Oddly enough, it is illegal in Michigan to use a boat you constructed. All boats and floatation devices must be commercial made and approved by some agency (Coast Guard?)
cesar harada (author)  chuckr447 years ago
in France this device was tolerated as long as it does involve only the person who constructed it (you cannot sell this kind of stuff), applicable on rivers not on the sea except very close to the border (less than 3 miles if I remember well) when the weather permits it (green, orange flag OK, not red X). I was paddling a lot on canals, since this raft wasn't motorised and shorter than 3m the law didn t allow me to go over most of the locks ... Means I had to take it out of the water, drive it after the lock, back in the water : tiring. My plan was to take it to the authority to legalise it >>> well this is what i had to say to the policemen so they leave me in peace ... Do the same, hopefully Michigan policemen are equally relaxed ...
That footage is bbbbuuuuttttttttttttttttttteeeerrr

Saw alot of vessels like this in district 7 Coast Guard of Florida. Usually had two or three Cuban refugees in them. This little bugger looks infinitely more seaworthy than some of the stuff I saw. Pretty neat.
