With a recent increase in ship capacity and propulsion performance, a wide-beam ship fitted with a twin-rudder system has been adopted in many cases. However, to improve ship manoeuvring, it is still necessary to have a better understanding of rudder-hull interactions in twin-rudder ships.

David Howe (May p18) and John Chapman (July p17) both make interesting points about whether a team of rowers could move a boat faster through the water by introducing a phase delay between strokes. However, neither author mentions the effect of the rudder. Typically located at the stern it is a self-imposed pivot point that prevents the boat from being

High-Performance Rudders—with Particular Reference to the Schilling Rudder
Marine Technology and SNAME News, 1987The evolution of the rudder as a means of steering or maneuvering ships has not kept up with other progress in ship machinery and propulsion systems. During the past decade, however, several significant advances in ship maneuvering have been made based on the principle of diverting the propulsive thrust rather than simply steering the hull.

Approximate calculation of rudder torque and rudder pressures1
International Shipbuilding Progress, 1955The study of tests on free rudder models enables an estimate to be made of the magnitude of the pressures, and consequently, of the moments, on rudder and rudder stocks In this way it is possible to take into account the particular circumstances of the working of a given rudder, so that it is no longer necessary to use textbook formulae of doubtful ...

Hydrodynamic Performance of Ichthyoid Rudder at Different Rudder Angle Settings
Journal of Coastal Research, 2016ABSTRACT Zhao, D.; Guo, C., and Su, Y., 2016. Hydrodynamic performance of ichthyoid rudder at different rudder angle settings. This paper presents the first calculation of the open-water hydrodynamic performance of ordinary and ichthyoid rudders in a viscous flow field using the computational fluid dynamics method as well as an investigation of the ...
