Nowadays, SPP (surface piercing propellers) are employed for many high speed planing crafts with high efficiency and excellent maneuverability. These types of the propeller are working at two interface physical conditions (air and water) and hirgh RPM, so, calculation of the hydrodynamic performance of the SPP are very complicated job. There are some geometrical and physical parameters that are affected to the hydrodynamics performance. The important parameters which effect to the performance are defined, such as; number of blades, pitch, immersion ratio and shaft inclinations, etc. We applied the boundary element method (BEM) and especial boundary conditions taken from experimental data by Ferrando et al.$^{[1-5]}$ for solving the hydrodynamic performance of the SPP. Two propellers, SPP-101 and SPP-102, are selected for calculation of hydrodynamic performance at various conditions. The predicted numerical results show that the present method is a good computational tool for computations of the hydrodynamic characteristics of SPP.
