The manoeuvrability was studied for the ship with this newly developed asymmetrical stern which contributes much to energy saving in propulsion. Two models were used for the typical manoeuvring tests, one was this new stern ship and the other was its parent ship having usual stern. The adoption of asymmetrical section rudder to this new stern was also studied and its effect was examined. The results show this new stern has good manoeuvrability as well as the parent usual stern and the adoption of asymmetrical rudder is effective.
