Cardboard Canoe!

Prototypes:

Our First Design
+:It was a great design; simple and had good aerodynamics.
Triangle-A little bit too complicated for the ammount of experience we had and required a lot of duct tape
?: Will it require too much time?
!-Make the nose flatter; easier to build
3 Features-This design had a pointed triangle nose, flat bottom and had the typical boat shape.
Key Feature-The key feature of this design was the triangle pointed nose.

Our Second Model/Design(The one we ended up using)
+-It was a very simple design so we couldn't really mess it up and it ended up floating quite well.
Triangle-We needed to make the bottom slightly curved so it would be more aerodynamic.
?-Will this design be fast or slow?
!-We could have added a fin more control over the steering.
3 Features: This model did not contain a pointed nose(Flat) but the nose was put an at an angle, had a flat bottom, and with moderate high walls.
Key Feature: Flat nose tip was the key feature of this design.

Our Third Design/Model
+-It would have been very buoyant; we would know that this would float for sure.
Triangle-Make the design so it would be able to have some speed or control.
?-Will we have enought materials to make this design?
!-If your going to make this, you need lots of duct tape!
3 Features- This design was completely different. Its base was mad like a raft(cardboard was made like logs), seemed very buoyant, but had no walls.
Key Feature: The log base was the key feature of this design.
