Short summary
In this research, a five-blade surface-piercing propeller was tested in the free surface water tunnel of Babol Noshirvani University of Technology to expand the experimental database for future engineering designs. The effect of immersion ratio and shaft inclination angle on the propeller's efficiency and hydrodynamic coefficients were examined. The highest efficiency of the propeller was achieved in the range of a 40 %–50 % immersion ratio at all angles of shaft inclination.
