Shipboard noise can be present steadily, during both work and leisure time. It can therefore not only affect the performance of their duties by crew members, but prevent recovery between watches. This constitutes a threat to the reliability of a ship's operation. Because the noise factor can also be important to the success or failure of a cruise, the economic factor must also be taken into account. The objective of this paper is not elaborations or a recounting of the latest developments in the field of shipboard acoustics. It deals, rather, with the economy and reliability of silent propulsion, exploring the questions of what it would cost to achieve and of whether the effort would be worthwhile. Following an introductory section that includes design criteria for cruising ships and ferries, there are sections on sources of noise in propulsion plants and on noise reduction in diesel, mechanical and electrical drives. Two examples of successful ships are discussed, followed by an evaluation of economy and reliability.
