In Marine crafts, especially in boats, by drawing the center of gravity down through aluminum super-structure systems, and thus balance of the boat is increased and provided more usage space. Poles of small boats and the yachts are made of aluminum. Aluminum alloys used in shipbuilding is known as marine grade aluminum (marine aluminum alloys) and they are classified, controlled and documented by class rules just like steel material.

The most important feature of aluminum; despite having almost the same yield stress as mild steel the density is approximately one third of the value of the steel. However, buckling resistance of aluminum is lower than that of steel, aluminum structures are about the half weight of equivalent steel structures.
