If you decide to use aluminum, it can be said that there are very few (ready-made) drawings, but it can also be said that there are many options (you have to modify it slightly).
Because of the price of aluminum and the required skills, generally self-built ships are less considered to be built with aluminum. So there are fewer ready-made drawings.
However, it is not difficult to convert the drawings of steel ships and plywood ships to aluminum plate manufacturing. For steel boats, it can be achieved simply by replacing all steel plates with aluminum plates of 1.5 to 2 times the thickness. You can easily find that such an aluminum hull is lighter than a steel hull. This is a great advantage, which will be reflected in the larger AVS angle of your boat, and the boat is more stable.
It is slightly difficult to convert plywood boats to aluminum plates. For a round chine plywood boat (round chine is made by overlapping multiple layers of thin plywood), it is very troublesome to change to aluminum.
Even if it is a polyline chine, about 40% to 50% of the thickness of the plywood aluminum plate is needed, which will increase the weight of the hull. You cannot use the principle of equal strength replacement to replace plywood with thinner aluminum plates, because this will cause some wall stability problems.
