Why Yacht Rudders Break

International Journal of Maritime Engineering, 2020
For most sailing yachts, losing a rudder is probably the most catastrophic structural failure other than losing the keel. Rudder failure happens with distressing regularity. This paper examines the hypothesis that the underlying reason is design failure. There are many qualitative decisions to be taken in the design calculation process.

Introducing an effective new ship rudder type, Telescopic Rudder

Archives of Civil and Mechanical Engineering, 2007
Rudder is the most important controlling device in ship maneuvering. Usually, it is a passive equipment of a ship, which generates the control forces and moments by inflow velocity and loses its performance when the ship speed reduces. Many parameters are involved in rudder design such as rudder's shape, area and span.

Approximate calculation of rudder torque and rudder pressures1

International Shipbuilding Progress, 1955
The 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 ...
