How to Make a Cardboard Canoe for Your Kids in the Pool
This instructable shows how my friend Jared, my brother, and I built a cardboard canoe for his kids to play with in the swimming pool.
Materials Used:
-Packing Tape - 1 1/2" - (lots(3 rolls))
-Cardboard - 1 sheet - 40" x 84"
-Utility knife (to cut the patterns out of the cardboard)
-Time (about 3-4 hours start to finish) (Not including CAD/Design/Snack time)
Step 1: Design the Canoe
We've attached the canoe design so that you can print it out and scale it to however big you want the canoe to be.
We printed the shapes out on an 11"x17" paper and made a model (see pics)
The final kids' canoe shapes were printed out just shy of 8' long.

Step 2: Get the Design Onto Cardboard
Now that we have our canoe design we needed to get it on the cardboard.
We decided to scale the pieces up to fit on a 40"x84" piece of double walled cardboard.
We projected the shapes using a laser galvanometer and traced them.
If you have access to a CNC, you could use that instead.
If you have a large laser cutter, that would work.
**UPDATE** You can use a normal computer projector (like for doing a power point presentation)
**UPDATE** You can print out the pattern and use an overhead projector.
If you are a very good artist, you could just copy the pattern using that grid technique that only works for a drawing of Mickey Mouse.
You can use the pattern and have it printed out on a large format printer like they have at copy stores(Kinkos) and then cut patterns out of paper to transfer it to the cardboard.

Cut Out Your Pieces
Use a razor knife to cut out the patterns. Since cardboard is difficult to cut, you may want to do an initial cut that just breaks the surface of the cardboard and then go back and cut all the way through. This may help you from making mis-cuts.
Use proper knife safety. Don't let your kids cut the cardboard. Don't cut any cheese during this step.

Step 3: Prep and Assemble the Pieces
Because the canoe needs to be as water tight as possible, we encased each piece in packing tape.
After taping each piece, tape the pieces together to form the finised canoe.
