When I tested materials a soft drink can floated well but filled with water because of the open holes. For this design i blocked both of the holes so it didn't fill with water and it didn’t sink. s00363057 https://padlet.com/s00363057/nd06n4x1nbc0ugwv/wish/3511447537 2025-07-06 09:44:51 UTC https://padlet.com/s00363057/nd06n4x1nbc0ugwv/wish/3511447537 The flat bottom boat floated best at the start, but the double hull stayed floating longer. It was more stable and didn't sink even when I pushed it a bit. s00363057 https://padlet.com/s00363057/nd06n4x1nbc0ugwv/wish/3511447674 2025-07-06 09:45:23 UTC https://padlet.com/s00363057/nd06n4x1nbc0ugwv/wish/3511447674 The catamaran was the best at floating. It stayed balanced the whole time and didn’t wobble. I think it worked well because the weight was spread evenly across both hulls. s00363057 https://padlet.com/s00363057/nd06n4x1nbc0ugwv/wish/3511448126 2025-07-06 09:46:36 UTC https://padlet.com/s00363057/nd06n4x1nbc0ugwv/wish/3511448126 The V-shape hull moved the furthest. It went fast and cut through the water. I think that shape is best if you want speed s00363057 https://padlet.com/s00363057/nd06n4x1nbc0ugwv/wish/3511450302 2025-07-06 09:54:44 UTC https://padlet.com/s00363057/nd06n4x1nbc0ugwv/wish/3511450302 The flat-bottomed design moved the furthest and in a pretty straight line. I think that’s because the wide base kept it spread across the water and the pointed front helped it cut through the water easily. s00363057 https://padlet.com/s00363057/nd06n4x1nbc0ugwv/wish/3511450418 2025-07-06 09:55:09 UTC https://padlet.com/s00363057/nd06n4x1nbc0ugwv/wish/3511450418 The V one. It was fast and went mostly straight. s00363057 https://padlet.com/s00363057/nd06n4x1nbc0ugwv/wish/3511450569 2025-07-06 09:55:51 UTC https://padlet.com/s00363057/nd06n4x1nbc0ugwv/wish/3511450569 The V-shape one moved the fastest and the wind helped push it. But it didn’t go as far as I hoped. The flat-bottomed hull went the furthest. I think it was because its wide base and edges was more area for the wind to push on. s00363057 https://padlet.com/s00363057/nd06n4x1nbc0ugwv/wish/3511452416

It tipped over when I put it in the water. I think the pointed bottom didn’t sit flat enough and the walls of the boat were too high. When i tried putting a rock in the boat it fixed the centre of gravity and the boat stopped tipping. s00363057 https://padlet.com/s00363057/nd06n4x1nbc0ugwv/wish/3511453476 2025-07-06 10:06:57 UTC https://padlet.com/s00363057/nd06n4x1nbc0ugwv/wish/3511453476 I made one hull out of cardboard and it got soggy. I think water got in and made it sink on one side. For my second hull design when i used cardboard I rapped it in tin foil so the water couldn't make it wet. s00363057 https://padlet.com/s00363057/nd06n4x1nbc0ugwv/wish/3511453617 2025-07-06 10:07:32 UTC https://padlet.com/s00363057/nd06n4x1nbc0ugwv/wish/3511453617 My round boat kept rolling over. I think it was because there was no flat part to keep it steady, and the wind caught it weirdly. s00363057 https://padlet.com/s00363057/nd06n4x1nbc0ugwv/wish/3511454233 2025-07-06 10:09:51 UTC https://padlet.com/s00363057/nd06n4x1nbc0ugwv/wish/3511454233 The sponge didn’t hold shape. I tried to bend it like a boat but it didn’t really work. When it soaked up water the boat sank. s00363057 https://padlet.com/s00363057/nd06n4x1nbc0ugwv/wish/3511454503 2025-07-06 10:11:27 UTC https://padlet.com/s00363057/nd06n4x1nbc0ugwv/wish/3511454503
