摘要

•Simultaneously considering hydrodynamic resistance and wake distortion is necessary.•Gradient-based optimization method allows large design freedom for hull shape.•The suction effect of propellers impacts the optimized shapes.•Imposing proper geometric constraints ensures practical hull shapes.
