Great small survival boat design. You can make it however you like, welding, stitch and glue, anything. Takes x2 sheets 4' X 8' material.
HOW I MADE MINE
I used x2 4' X 8' sheets water grade lumber from my local wood supplier. Printed full scale at a print shop, glued to the wood, jig sawed out, holes drilled along the perimeter, zip tied together, glued with fiberglass epoxy mixed with fine saw dust (peanut butter like), and then cut the ties, glued the rest of all the seems, and then fiber glassed the outside of the boat and some insides. I actually painted mine with spray paint because will be nice to touch it up periodically, changing it's color.
