The first cardboard boat was completely assembled this afternoon. Now the students need to spend time painting the skin with polyurethane sealant to keep out the water. After it is sealed, they will then paint the boat with some sort of color scheme, and from our discussions it appears they want to try and make it look like a leaf. Should be interesting. The cardboard boat races are just over a week away, so I think they are in a decent place to get it completed and ready for the water. A few photos below.
