After searching the literature the closest thing to what we (my
brother and I) want to build is called the "Aqua-Glider" which is made
mostly out of wood. I thought we might copy the design but substitute
materials.

The last thing I want to do is to squash your dream, or to be mean. I have to
be concerned with your plans from what questions you asked.

I would respectfully ask if you should be planning to change a design. If you
have to ask some of these questions, especially since some of the questions are
very basic, you are not ready to take on redesigning. You should either build
the plan as it is drawn, or spend a few more years learning before you start
building.
