The book begins by performing a critical review of existing approaches for dealing with Ship Maneuverability and Ship Safety before considering fresh understandings of these terms. Different attempts to integrate Safety with Maneuverability are then examined. The weak features of these attempts are considered and scope for developing fresh approaches is then presented. This is followed by an explanation of alternative new ways of treating a ship's maneuverability. In order to meet the requirements for operational specifications and safety in a cost-effective way, the book proposes an approach for relating Safety with Maneuverability in the appropriate phases of a ship’s life cycle. The approach is based on a preventive Safety Methodology while introducing fresh indices and criteria for assessing the ship's maneuverability. Two case examples are used to show how the methodology can offer an effective approach for designing and operating ships that can meet improved maneuvering-safety requirements. One case example studies a dry cargo ship of a Mariner Type while the other studies a service ship of a Jackclass Type. Free running model testing is used to verify the results of the Jackclass type
