The best boat design that I found was flat and small walls. It held a load of 413 Lbs. the reason this one worked best is because it held more air and had more space for the copper. The more air it can hold the less dense the boat will be. It also worked well because of the water salinity and temperature, the water salinity and temperature were. Salinity: fresh water. Temperature: cold. The water condition was smooth. My research group tested a total of 4 boat designs, 1 was long but thin with high walls, it sunk at 110 lbs. 2 was a half inverted cone, it sunk at 200 lbs. 3 was circular with low walls, it sunk at 70 lbs. 4 was flat and wide with low walls, it sunk at 413 lbs. some of the dangers that were faced during the testing were storms, rough waters and icebergs.
