After I lined the inside with thin fiberglass layer, I opted for the use of polyurethane foam. it is mild and help the floatability in case of accidents. As well as helping to the firmness of the assembly
After the "pie" dry, I cut and sanded the excess, preparing the surface to the upper hull.
I coat the inside of the hull with a thin layer of fiberglass before it closes. This will eventually contribute to a better waterproofing and firmness of the hull
The first run of my little model made in balsa wood in the lake. I have corrected the problems with the engines heating and cavitation. As I said before this is a first stage. The next version will be improved some aspects of the hull design and assembly.
