The propulsion and the motions of two shipmodels were measured in longitudinal regular head waves. The first model is a parent form of the Series Sixty and has a block coefficient C B = 0.65 . The other model has the same afterbody and block coefficient but is fitted with a 10% bulbous bow and a correspondingly modified entrance.

    The experimental results in regular waves were used to predict the behaviour in irregular waves. It is shown that the influence of the bulbous bow on the motions in longitudinal irregular waves is small. The increase in power, due to the sea waves is larger for the bulbous bow model.
