Descrição: Changes in transverse stability can occur between the "as designed" condition and the ship "as built" and in motion in a seaway. This paper investigates the hull shape which would be required to retain a constant GZ curve in these changed conditions. For constant initial stability it is found that the sections at the waterline should slope normal to a line through the metacentre. Using a pressure vector approach, a better understanding of how section shape contributes to stability is developed. This approach is extended to non-hydrostatic pressure distributions. It is shown that there are small metacentric height changes at the crest and trough of a wave which are in opposite directions for Vee and Wall sided sections.
