  & Analysis

  Model resistance, propulsion, and cavitation under full-scale conditions

• 03
  Design
  Optimization

  Refine propeller and ESD geometries for maximum efficiency

• 04
  Performance
  Verification

  Ensure reliable operation in real-world sailing conditions

Why CFD Matters

• 

  Accurate full-scale prediction without costly towing-tank tests

• 

  Rapid evaluation for retrofit decision-making under tight schedules

• 

  Data-driven optimization that improves efficiency and compliance

• 

  Reliable validation of hydrodynamics, vibration, and noise performance
