A little boat like a floating papasan chair. Perfect to lay in and look at the sky.
Exactly big enough for two people to snuggle.
The supermodels in the boat are Arwen and Saul.
This boat is part umiak, part currach, part coracle, part papasan chair.
Here's how to make a tougher skin for it from truck tarp material.
The book "Umiak" by Skip Snaith will fill in any construction details that aren't clear here.

Step 1: Stems

The boat ended up being 9'6" long, 43" wide (measuring to the outside edges of the boat, and 18" deep in the middle (measured on the inside of the boat.)

The first step was making the stems.
I sketched them out freehand and cut them from 3/8" marine okoume plywood.

To beef up and widen the outer edge I glued on some more plywood using epoxy thickened with wood dust as seen here.
White flour works just as well, whole wheat flour doesn't. Don't use 5 minute epoxy for anything, it's not waterproof.

If I did it again I'd make the stems taller and not nearly as beefy.
<p>Really impressive, thanks for putting this up. What quantity of roof paint did you use? It's pretty expensive here and I'd like to get the right amount the first time.</p><p>Thanks!</p>
Nice job, nice boat. One correction; 5 minute epoxy is waterproof, I've used it as an emergency repair on boats below the waterline and it's lasted fine.
I quite liked your home made boat.I made one myself and entered it in i think it was summer watercraft challenge on instructables last year.I made a frame on skin idea but used upvc planks like used for making double glazing window frame,plastic sheeting on the outside for a skin and blocks of foam and plastic bottles stuffed inside it for bouyancy.Was about 5 ft 5 inches length by 4ft in middle-beam at widest point and drew about 5-6 inches.A few pictures attached....
where do you find Papasan chairs?
I just found one in a dumpster!!
The ARC, Goodwill, alleys, yardsales... Most folks are trying to get rid of them.
pier1, world market, walmart (maybe), tons of places, all over the internet
ur welcome :)
could i build a skeleton out of bamboo? i have a lot that grows right down the street on property where the people who own the land let me pick it. :)
Yes. Do it.Do it now! You'll never regret it.
Wrap, bind and duct-tape the joints before you skin it. Bamboo is extremely sharp on split edges and &quot;splinters&quot; (Google &quot;punjie sticks&quot;). Also, check out the Gaelic skin boats, I think the spelling is &quot;camragh&quot;. They are brush rings bound about in a doughnut fashion and then laid on a tarp (skin) and then pulled inside and ticked under the brush ring. Paddle away! I pray you can swim, or have rescuers around the pool with a line. Keep trying.
well it was cold when we sank, we were in jeans and heavy coats...... and thanks for the tips <br>
I like your vice.<br />
nice.... now if it could only fly....
So if there are wheels on the up side of it, does that mean that it can be flipped over and doubled up as a land vehicle too?
yes indeed. just flip it upside down and it's a wagon.
Saul looks like Will Ferrell.
A beautiful instructable. BTW, where did you find the roof paint? It looks perfect for another project I am working on.
I got it at a home depot in Massachusetts. It's "snow roof systems" brand. The black stuff is a lot more elastic than the white stuff. It's waterbased and very thick. Pretty much anything you can paint on cotton canvas will work well. If the skin is nylon your coating has to encapsulate it perfectly or it'll get loose when it's wet.
i live in masserchuset (trying to type local dialect). alot of the materials here are more for colder conditions. what town was the home depot in.
nice I could have some fun with this
To see a good idea for sails go to this site<br/> <a rel="nofollow" href="http://www.wbm.org.uk/page2.html.">http://www.wbm.org.uk/page2.html.</a> This is similar to a traditional fishing boat called a &quot;Somerset Flatner&quot;. Somerset is a county in England and is / was used on inshore waters for fishing. When I was messing about with such boats a few years ago I came up with the idea of making a 'skin' out of a builder's / farmer's tarpaulin and getting silicone sealant ( the stuff used to seal around work-tops in kitchens and bathrooms) and smearing it with a spatular all over the skin to make it one piece and water tight. However the tarps are polythene and the silicon sealant didn't bond very well but I'm sure someone can come up with a better sheet material even if it's cotton. The cotton won't rot because it won't get wet. So perhaps next summer I will have another go at this. Nice job.<br/>
The link doesn't work because of the period at the end. if you clcick on the link just remove the period from the address in your browser. It is a great site.
Buy a decorators plastic backed coversheet. Put the plastic side out.
how much does this weigh? do you think it would be sturdy enough to stand(carefully) in it? great instructable by the way
Oh my god, I love you Tim! SEE YOU IN FRANCE! haha, laughing my a$$ off!
This is great! I'm wondering about the dimensions. How long is this boat? Happy floating!
The boat ended up being 9'6" long, 43" wide (measuring to the outside edges of the boat, and 18" deep in the middle (measured on the inside of the boat.)
On the second image in the intro, whats that grey triangle shape near the bottom righthand cornner?
dude i gots ta gets me one of these! (first a girl for the "cudling" part is nesesaery
I think the wheels on the back are a very clever idea, i think i may have a go. Thanks
I am VERY VERY Impressed. We bout a 2nd hand canoe and we love it. I always wanted to make one by had. a Friend of mine mad a boat out or wood buy hand. Nothing fancy and painted the bottom white so it looked like a normal boat. He sold it for $25,000!!! The guy wanted more from him. Its amazing what hade made stuff can be worth. It was like a little jon boat.
here is a kayak site to build your own. the skin in this project seems good?<br/><a rel="nofollow" href="http://yostwerks.com/DesignsMenu.html">http://yostwerks.com/DesignsMenu.html</a><br/>fabrics<br/><a rel="nofollow" href="http://www.owfinc.com/Fabrics/fabricmain.htm">http://www.owfinc.com/Fabrics/fabricmain.htm</a><br/><a rel="nofollow" href="http://www.rockywoods.com/breathables_main.htm">http://www.rockywoods.com/breathables_main.htm</a><br/><a rel="nofollow" href="http://www.seattlefabrics.com/neoprene.html">http://www.seattlefabrics.com/neoprene.html</a><br/>
but.... maby u can have an outboard motor or paddles?and just a bit bigger to have 4 people in it? or size it down for a swett pool toy?
An outboard motor would weigh probobly as much as the boat. A trolling motor with a transom mount would be good, but then you couldnt haul it by bike.
cool boat i may try it in the summer time!
Great article. I learned something on some skin on frame site. I think the tippyness may result from being so round bottomed. The site I looked at the guy made his ribs with a nice arc. He test floated it in the pool with a temporary plastic drop cloth skin. Too tippy, pulled all the ribs out, made them a very boxy, flat bottomed U shape by thinning the ribs at the corners of the U and that worked out well.<br/><br/>I admire the heck out of you guys for trying and succeeding. You might want to check out <a rel="nofollow" href="http://capefalconkayak.com/jwboat.html">http://capefalconkayak.com/jwboat.html</a> to see a slightly bigger, but suprisingly similar boat that was featured on the cover of woodenboat magazine in august.<br/>
Lucky bastard gets a boat, and a pac-man machine???? How does that seem fair???
This really is a great instructable! I've seen several comments on possible additions (ex./ outboard motor). I thought a good suggestion could be a form of canopy, perhaps something that would fold down like a convertible car top. Heck, you could make it from a tarp! Approx. how much time and $ went into this project? Thanks again! By the way... is that Pac-Man I see in your workshop?
I salute you,I would never have the confidence to so out in deep ,cold ,water, risking death by drowning in something I had built.
This is the coolest project I've seen here! What do you think about using "wire ties" instead of your inner tube strips?
I tried to make a boat frame with wire ties once. They broke easily and slipped, the joints weren't strong. A little sunshine made them really brittle. It looked really bad. Lashing the joints with string then soaking the string in epoxy is much better. A little slower to do than innertubes, much better looking, stronger, more permanent. I've never found a good use for wire ties except tying wires. When I need them for that they're gone because someone used them all up to make their project look like a bird on drugs did it in a panic. Wire ties are really great for tying wires. Much better than the waxed string that was used before. That waxed string makes good dental floss if you peel out some of the fibers. A spool of that will last you five lifetimes.
I aggree with you TA. wire tie are way too brittle. There is an alternative however. I would look at Spectra cordage. We have good success with it for lashing both Bamboo and Composite tubing.<br/>Here are some links: The first one is from Honeywell the makers &#8211; <a rel="nofollow" href="http://www.honeywell.com/sites/sm/afc/spectra_fiber.htm">http://www.honeywell.com/sites/sm/afc/spectra_fiber.htm</a> We have good success and friendly service from Donaldson <a rel="nofollow" href="http://www.donaldsonrope.com">http://www.donaldsonrope.com</a> and good technical support from Samson themselves <a rel="nofollow" href="http://www.samsonrope.com/">http://www.samsonrope.com/</a> <br/>However any supplier worth their salt will be able to get it for you. If you are around a harbor that has race boats, you can make friends with the crews and riggers and likely get anything they want just for the asking or help along the way. <br/>
Thanks for the encouragement. I wish I'd said something more encouraging back.<br/>Take a look at <a rel="nofollow" href="http://www.yostwerks.com/">http://www.yostwerks.com/</a> to see some other very slick skin-on-frame plans.<br/>
Now that's a REAL instructable. Still, I wish there was more detail. How would you attach a sail or a motor to the boat. Also, those bike tires gave me an idea. How about attaching them to some gears for a laid-back paddle boat?
My best suggestion would be a kite. On the paddle system, there is one indevelopment at ABOTA. I will post the rig as soon as it is tested in Early 06/09.
This is brilliant! If you wanted to add a motor, I'd go for a small electric outboard off the back, rather than anything like a speedboat engine(!) Of course, if you are a cyclist anyway, a recumbent bike setup to drive those wheels as a paddle steamer affair would be entirely brilliant! You would have to have a way to add some fins to the wheels to actually have them drive, of course. But since the trailer boat doesn't lean during transit, you could simply permanently mod the wheels to be paddles as well, without much issue.
