hi this is my entry to the hull designthis design is a freeform I got the idea is to use a concave bottom surface with pressurized air to form a kind of air bed this way it eliminates the contact between water and bottom surface in addition the design supposes that the hull texture should be hydrophobic witch cannot be shown in the 3D model or at least hydrophobic coating another addition is in the top view I tried to mimic a naca profile with the restrained ratioI got software issues to simulate multiphase flow so I did a simulation with roughness 120micron for the modeland ideal wall for the bottom surface as an approximation for the air bed
