I have to build a cardboard boat using only cardboard and duct tape.
What kind of shape/design should I use to make it go faster and go
through the water faster? Any building tips would be helpful too. The
paddles must be amde out of cardbaot and duct tape also.

There was a query like this about a year ago. The consensus was, "use LOTS
of duct tape, and paddle fast!"
The guy did the race, and later reported that the organizers provided a
specific quantity of cardboard and of duct tape -- not enough tape to
waterproof both the outside and inside of his hull.
He rowed like crazy, water came over the gunwales, the cardboard got soaked,
and -- voila -- folding boat. But he had a ball!
