✦ Synopsis

The main aim is to give an introduction and awareness to those interested in Ship Design and Ship Performance. It is written to underpin and support the more erudite books published on Naval Architecture and Marine Engineering by Elsevier Ltd. It will also bring together the works of Masters, Mates, Marine Engineers and Naval Architects engaged in day-to-day operation of ships at sea and in port.
