Week 25

We had cardboard bout races and a lot of the boats sank really easy. Some factors are that it did not have enough layers on it. The boats that worked out the best had 2 layers. Another factor is the weight of each person in the boat. If one guy is heavier then that side is gonna sink. You had to build your boat around your rowers. Last factor is the boat was not symmetrical. Some boats had more stuff on one side of the boat which made it easier to sink on that side. But some boats did not sink. Those boats didn't sink because they used there minds and thought what would be more stable in the water. 2 layers and long boats worked out the best. The lowest center of mass is the most stable. The groups could use this to determine how to build their boats and where to place themselves in the boats. Our boat did very well. We made it there and back and when we took it out of the water it easily could of went 10 more races. It was that stable. We really didn't have any problems except for is running into the barrier thing. The best rowing technique would be one person row on one side and the other person row on the other side. You keep the boat balanced and you get the most speed. What my group and I do differently? Probably plan it out more. We did very well with the construction of the boat. I would not change a lot.
