A popster above suggested thinking of the bottles as other than a
flotation force.

I agree. What about cutting off the top and bottom, then cutting
down the length to create a plastic rectangle (albeit one that wants
to roll back up!), and use these as a hull material
overlaid/glued/sealed together as one would shingles on a roof. This
could be done over a very light "baidarka"-like frame (see baidarka
articles in WoodenBoat). There have been articles in Mother Earth
news about people that have done this with endless piles of beer cans
to literally shingle a roof with aluminum -- beer cans with ends cut
off and opened up to their rectangular panel.

It may take a lot of beer to actually contemplate such a thing, but
its been done. So why not with plastic for a simple boat. Wow! It
would be equivalent to a glass-bottomed craft for a great underwater
view!

I want to build a boat out of two liter soda bottles.
Why? Why not? I can make the time and the space to do it and it's
something I've wanted to do for a while.
I've looked on the web, but haven't found any sites on doing something
like this or any people who have done anything like this.

So, my question, does anyone know of any web sites that talk about
something like this or people who have an idea of how to go about
something like this?
I'm an engineer, so I've got some ideas on how to start, but would
like to see what others have done and have someone to bounce ideas
off.

Thanks
