The purpose of this paper is to provide the naval architect with a practical methodw of estimating hydrodynamic force and torque acting on a horn-type rudder. Such a rudder is also known as a Mariner, semibalanced
underhung rudder or skeg-rudder. Input required to carry out the estimate is explained and the reliability of the estimate is discussed by comparison with model test predictions. A spreadsheet, named H-Rudder
program, is provided to carry out the estimate.
