Even on a plain boat, the cost of the aluminum plating will be less than 5% of the total cost. Framing and welding supplies will be more. Aluminum can be recycled, but what you will sell the scrap for is not much. Trading vessels are heavy. They need to be for the abuse they get when working. Unless you have at least a preliminary design (not simply a drawing) , the calculations make no sense. The shape of the hull, the framing type, what class or other regulations to comply with, area of operation, etc. will determine and drive the design and cost.
