Step 1: Materials
My materials list came out to this:
Three 55 yard rols of duct tape
8 cedar strips
1 bottle of gorilla wood glue
Altogether less than 20$.
Step 2: Design
Once the frame is made, the "skin" of the boat -which consists of two layers of duct tape- stretches across the frame.
Step 3: Frame
Using 2 angled brace strips, bend the edge pieces and clamp them into place. Glue the seams between the braces and the edge pieces. (see Pictures 1 and 2)
The "hull" piece consists of two angled pieces held between two straight strips. Once glued and attached, this piece constitutes the bottom edge of the kayak. (see Pictures 3, 4, and 5)
As shown in Picture 6, cut out the vertical brace pieces that connect the horizontal braces in Step 1 to the "hull" piece in Step 2. Attach them as shown. (see Pictures 6, 7, and 8)
Cut out and attach the "ribs" to the bottom edge of the boat and the curved side strips of the frame. My particular design included 6 of these "ribs" on each side. (see Pictures 9 and 10)
Cut one of the full length strips into two thinner pieces; attach these at the front and back of the kayak and secure them about halfway along each of the "ribs". (see Picture 11)
Now you're finished with the frame!
Step 4: Duct Tape!
Additional layers can be added to increase strength and waterproof-ness, but at this point you're finished with the "skin" of the kayak.
Step 5: You're Finished!
I would recommend taking time to smooth down all the duct tape seams to make sure they are tight and smooth. The last thing you want is water seeping its way into your Duct Tape Kayak!
Good Luck and enjoy skimming through the water in your sleek Duct Tape Kayak!
