Cardboard Canoe Challenge: Design Phase

SKETCH:
First Idea:

Second Idea:

Third (Final) Idea:

PROTOTYPES:

First Prototype:

- Flat Bottom

- Curved, pointed bow

- High Walls

Second Prototype:

- V-Shaped Bottom

- High Walls

- Short Length

Third (Final) Prototype:

- Flat Bottom

- Not so high of walls (easier paddling?)
- Rectangle with a pointed front (stable)
DESIGN SELECTION:
First Idea:
+ - flat bottom for stability
Change - High walls
? - What is the optimal boat length?
! - Shorten the walls and make it longer
Second Idea:
+ - V bottom for straightness
Change - High Walls
? - Should a flat bottom or v shaped bottom be used?
! - Use a flat bottom and shorten the walls and make it longer
Final Idea:
+ - Flat bottom and optimal length
Change - Final Idea- no need for a change
? - How should we propel the boat? (pulling or paddling)
! - Pulling could be faster and easier for the pilot to keep the boat stable
MATRIX:
First: short, high walls, flat bottom, one point in front, curved bow
Second: short, high walls, curved bottom, two points, looks a lot like a regular canoe
Third: longer (optimal lengthe between speed and handling), shorter walls, flat bottom, one point in front, point is slightly curved
We will use the third and final prototype for our cardboard boat.
