Today's concept was to roll out a bunch of iterations for our boat design. We started with a very basic 2D platform with slots to accommodate 6-inch paddle wheels. (1) The first iteration of the platform was quite slow because it had a high water level with respect to the platform (about half inch), so the paddle wheel was dragging a lot of water. (2) The second iteration consisted of us putting a thin piece of foam underneath it. This made the paddles submerge less and consequently made the boat faster. (3) We noticed that the paddle wheel kicked up water in its slot, leaving the water nowhere to go but back onto the paddle wheel, substantially slowing us down. We cut out slots to accommodate these streamlines, making the platform look like a boat with two pontoons. This made the boat a whole lot faster. (4) There was a lot of rippling happening at the front of the boat, so we put a draft at the front of the boat, which made it ride a lot smoother.
