Today, we officially started prototyping based on our second sketch. Since we are building a boat and we don't have any access to plastic materials, we decided to use foam boards. We cut off two trapezoid shaped pieces for the rear and two rectangular pieces for the bottom and back. Eventually, we glued the pieces together and on top of that, we also spray painted them in light blue. It was a good day of work and we got a lot of things done.
