This deals with model test results of a container vessel having a low block coefficient. It was fitted with an asymmetric afterbody in order to improve the water flow to the propeller and thus the propulsion. Power savings of more than 7% were attained. Calculations based on the wake distribution measurements showed that the variations of forces and moments at the propeller shaft were markedly below the permissible limits and that the pressure fluctuations on the shell could be reduced considerably.
