A three-dimensional low-order boundary element method is presented for the performance prediction of surface-piercing propellers. The negative image method is used to account for free surface effects. Detachment locations of ventilated cavities are searched for iteratively using a modified smooth detachment condition. Results from parametric studies and validations with experimental measurements are shown.
