Half scratch build model in 1:48 scale.
As a basis I took the model from the Model Shipyard - Just take a book from the series "Anatomy of the Ship" - "The 100-gun ship Victory" by John McKay.
I increased the size of the model in 2 times, for the scale 1:48.
To produce the frames, keel and other elements of the design, I took the Foam board (5 mm), several kinds of cardboard. Deck - veneer of pine.
Sheathing boards as a cardboard (1 mm).
