Since the water density is greater than the boat, it will float.
Assessment of my boat's strengths and weaknesses.
1. (a) How successful was your boat in meeting the design requirement ? My boat was successful design wise, because it looks very good, it also reflects a catamaran which has a very specific and futuristic design. Including 3 shells a catamaran is already pretty, but I went even further I added one more shell it makes it even more artistic and futuristic. (b) How did your boat's buoyancy compare with the other boats when tested by increasing the mass ? Sadly the biggest weakness of my boat was buoyancy. My boat still floated when we put a lot of coins, the only problem was that is will flip over when the coins weren't distributed equivalently. So the buoyancy of my boat was pretty good if all the coins were distributed equally, when the coins were not equally distributed I could still fit 3 coins. (c) How stable was your boat when compared with the others? My boat was pretty stable, the 3 shells helped a lot because the 3 parts help how the boat reacts within the density of the water.
2. What changes would you make to your boat if you were to print it again ? I think I would change in my boat, I think I would add two shells horizontally. What I mean with this is that if they had two other shells it would makes a square. I will show you want I mean in the picture.
