Aluminium has become the material of choice for performance-oriented superyachts. At 40 metres, the weight savings compared to steel translate directly into higher top speeds, better fuel economy, and increased range. Aluminium also offers excellent corrosion resistance in marine environments and is highly receptive to custom fabrication, allowing naval architects to create hull forms and structural details that would be difficult or impossible in heavier materials. The result is a yacht that is lighter, faster, and more responsive.
