1) three factors that could have caused the boat to sink, 1, the lack of support on the bottom. So if a person who weighs 100 pounds puts weight on the boat, it shouldn't just have 1 piece of cardboard trying to hold them up, its going to collapse. 2, the height of the boat, If the boat was to short, when they sat down its obviously going to go down a bit, and if its too short water will seep through. 3 You also need enough cardboard to support the "forsaking".
2) The ones that didn't sink, had supportive structure and enough tape for the water to not sink in.
3) The lowest center of mass is helpful because it allows people to know where to sit in the boat, and how they should stay.
4) our boat did a lot better than i thought it would. It stayed afloat, the only trouble we had was how to row. I was rowing too hard, compared to the other rower. and so it took us a while to get down and back.
5) best rowing technique would be not at the same time, and have each on one side, not switching.
6) if i had to do something different i would have worked on how to row, and practiced.
