This paper addresses prediction of ship motion and propulsion system behaviour to demonstrate the effect of waves in real sea states. For a 8000 t deadweight tanker, three different stem shapes are studied experimentally and numerically. Numerical simulations of speed loss were performed in time and frequency domain, generally agreeing well with experimental results. While a conventional bow with bulb and flare gave least calm water resistance, a bow without bulb and flare gave least total resistance in severe wave conditions.
