MANOEUVRING CHARACTERISTICS OF SHIPS

The Author, of the Fachhochschule, Hamburg, has (with the support of J. Brix of the HSVA) carried out a study on the manoeuvring characteristics of ships from the mariner's viewpoint, and here presents the part of the study dealing with the position of the centre of rotation, i.e. the point on the ship's longitudinal axis, or on the extension of the axis ahead or astern, where there is no transverse motion during a turn. The position of this point (which is not static) depends on the points of application of the transverse forces acting on the ship and on the relative magnitudes of these forces; it is only slightly affected by the ship's speed and trim. In further articles to be published in Hansa, the Author will deal with course stability and turning ability. The present article is arranged under the headings:-- Important Manoeuvring Characteristics. Definitions and Preliminary Remarks. Position of the Centre of Rotation. Assessment of Interrelationships. General--Turning in a Confined Space--Turning with the Rudder during Ahead Motion--The Centre of Rotation in Astern Motion of a Single-Screw Ship with a Right-Hand Propeller. Points of Application of Transverse forces. General--A Single Transverse Force Applied to the Ship--Two Opposing Transverse Forces Applied to the Ship--Two Parallel Transverse Forces Applied to the Ship. Order from: BSRA as No. 48,154.
