There have been a few canoe like objects put up on instructables but this one is really a pirogue- or flat bottom canoe. There is actually a lot of theory on boats like this one but the basic idea is you take two planks, stick them together at the ends with a frame or two in the middle, fill in the hole in the bottom with another plank and then add decks and thwarts and yokes and outriggers and sails and whatever else you feel like.

This boat is made from one sheet of 4mm marine ply for the sides, one sheet of 6mm marine ply, for the bottom and some sticks, fibreglass and epoxy to stop the thing from falling apart and to give yourself somewhere moderately comfortable to sit.

Most of the layout for this example comes from free sources on the web which I will include reference to where I deem I feel like it, but the main one is the lazy weekend canoe from the Toledo Community Boathouse
This design is 6/7 of a Lazy weekend canoe, being 12 rather than 14 inches high and built using only 2 sheets of plywood instead of 3.

The canoe is a basic plan intended for two people and fishing gear on calm waters. Emergency floatation will be something like pool noodles tied under the seats and a beanbag cushion for the center. The back seat has a low back rest but the front is intended to be used in reverse when paddled single handed.

The woodworking skills required here are minimal and if you use epoxy, any mistakes are easily covered up, or filled.

In this layout it would traditionally be propelled by two people with one ended paddles paddling one side each. Two ended paddles can be used but to clear the sides easily you might need to make an extra long one. "Real" two ended paddlers will fit the length of the paddle to the person rather than the boat, which is fine till you are paddling something too wide for how you are tall. More on this in step 17 - water trials.

This is the perfect boat to use for your uke'n'paddle.

Step 1: Buy Some Plywood

Buying plywood is one of the trickiest steps:

  • Marine plywood should be OK but sometimes isn't;
  • Exterior or structural plywood should be kind of OK but may have some bits that may require patching later (voids)and may not be as pretty and may have a good and a bad side;
  • Interior or non-structural plywood is probably not to be trusted.

Plywood also comes graded by the faces
A = A really excellent face
B = Nice but might be small imperfections
C = Could be better - small filled holes allowable
D = Don't go there girlfriend, or Decorative.

AA is usually sold as marine ply.
ACX or BCX (with the X standing for exterior) has frequently been used for making boats.

I used CD exterior pine plywood to make my wacky lassie and apart from having to do some patching of voids it has held up pretty well. I would not however recommend it.

Marine ply is usually stamped with a standard and most use the BS1008 British standard. The Australian standard is AS2272. If you do not live in Britain or other place that has mandated the British standards, the BS1008 stamp has no legal meaning. This does not stop many people (some of them unscrupulous) from using it anyway.

My plywood was 2440 by 1220 mm, which is so close to 8 foot by 4 foot given my accuracy we may as well call them 8 by 4 sheets.

how would you go about adding a sail?
The West Mersey Duck punt is a sail boat with very similar dimensions. <br>http://www.keepturningleft.co.uk/blogs/build-a-duck-punt-the-best-fun-an-old-man-can-have-lying-down/ <br> <br>This makes it a one person laying down sail boat which means it does not carry as much weight so needs less rocker so the sides are more vertical but by my reading that is about all the difference in the hull. There are great plans available for them with thole pins and old style home build-able sail configuration <br> <br>or Mik Storer's drop in rig <br>http://www.storerboatplans.com/Canoebits/KayakRig.html <br> <br> <br>Sailing canoes of this size looks to me like a great way to have fun in as well as on the water. <br> <br>Add outriggers and lots of reserve buoyancy as well if you feel the need for safety. <br>
<p>How many meters of fiberglass did you use ? thanks.</p>
I am not sure how much I used precicely because I just bought a 30 meter roll and used what I needed and had some left over.<br>Estimating at 4.6 meters for the bottom joint times 4 (inside and out 2 sides) and a meter or so for the stems and 2 meters times 2 for the panel joints gives around 24 meters.
<p>beautiful work. what are the final dimensions / weight of the canoe?</p>
<p>I had one of these, I bought built from a retired MFG boat builder. His modifications were slightly deeper keel, aggressively taller angle at waterline (between the bottom section and gunwale section), no center cross support, adding a rib instead, and seats directly on the bottom. The top of canoe was covered with 3 pieces of canvas, with velcro openings at seating positions. It was the fastest, stablest, straightest paddling canoe I have ever been in. With his modifications I would commonly stand in the canoe to fish. </p><p>Further from use experience I would raise the gunwale. I would consider covering the inside of bottom with foam, for buoyancy and insulation, as this design will sink. I would also allow the rear seat position to move forward 1 position for 1 person balance.</p>
How heavy would you say it is? Is it easy to load on a car?
<p>From a scientific ly accurate point of view this one wrghs in at 29 kgs, or 65lbs I can carry it and load it on to my car without too much trouble but I am a big boofy bloke. The OHS people would recommend a two person lift. </p><p>You may be able to make a lighter version by using removable or Woven seats for example.</p>
<p>Hey that is an awesome build! I was just wondering how thick is the plywood you used for the sides? Thanks!</p>
<p>The sides are made from 4mm ply = just over 1/8 inch </p><p>The bottom is 6mm = a touch under 1/4 inch</p>
<p>Oh wow so the bottom is quite thin as well as the sides. Thank you very much I appreciate the help! </p>
<p>How is the stability of Neef? I made a similar boat using the plans from bateau2 but if you sat more than a couple of inches off the bottom it wobbled like crazy. I tried it sitting on seats about the same height as yours and nearly capsized.</p>
<p>The extra 10 or so inches of width make a big difference to the stability over similar 24 inch at base wide canoes. I have no problems once seated and if you have one person seated then that really makes it OK to move about a bit as well. On the other hand the narrower hull will paddle easier and the bateau boats plans are shaped for more directional stability making it easier to keep going in a straight line. If I used mine more I would add a skeg to sort that out a bit.</p>
<p>The &quot;X&quot; actually stands for exposure, not exterior. It refers to the type of glue used and means it can be exposed to certain elements. &quot;exterior&quot; is close though :) </p>
very nice
I built a boat similar in design for small child. I used a single 4x10 ft sheet of mahogany marine plywood from Eden Hardwoods in WA state. It is possible to use a marine grade construction adhesive if you use chines at all of the corner joints. If you want go with epoxy, I recommend system three epoxies. Epoxy is messy and I developed a sensitivity to it so be forewarned. Nice job!

It was recommended to me to paint my plywood boat with exterior house paint. The reason was that paint companies put the most research and development into making a good house paint since that is what they sell the most of. No need to buy special paint for a boat as long as you don't leave it in the water.
Yes - Paint manufacturers treat boat paints like hairdressers treat wedding parties. As soon as the word boat reaches their ears their eyes light up with little dollar signs.
Fantastic ible! Very thorough and with good pics as well. Not only did I give you some votes; I am saving this for when the weather warms up a bit to give this a try. Though I feel silly saying that with it almost Christmas and in the low 40s.
Nice job! I also liked the cedar strip canoe I found on here. check it out at https://www.instructables.com/id/Building-A-Cedar-Strip-Canoe/
Hmmm. I may have a go at this. Many thanks for sharing. Really good! ;)
İf you have plans for a stand up paddleboard that would be an awesome share!
I have not made one personally but there are people who have used the kayak foundry software to generate forms for building using strip build techniques, which is a step above what I have done. Check out their forum for a few examples. <br>http://www.blueheronkayaks.com/phpBB2/index.php <br>Alternatively I have heard of things as simple as a long box with a slight bit of rocker put into the bottom being built and used. <br>
Great instructable indeed. i've made a portuguese Style dinghy but i didnt finish the paint job eigther so i didnt share it yet. Your instructable gave me courage and i'll share it anyway. i was planning to make a simple canoe as a winter/indoor project which Will be ready for the coming spring and whole summer of course. This instructable would be very helpful. Thanks...
You have a great deal of courage to undertake this project. Thank you for sharing it with us &amp; have a Merry Christmas.
Beautiful boat! Thank you for sharing this!
