    You take the ratio of the sail height on the model to the scale of 5 cm. Then you multiply this value times the scale value of 4ft

    Ah I see what you were talking about. I thought you were asking to do a metric conversion.

    every 5centimeter of his model stands for 4 feet so write a proportion 5cm/4 ft = 22cm/x ft
