Abstract
The stopping ability of a ship is usually represented by the so-called "head-reach", which is measured at the official backing test. Head-reach is defined as the distance traveled by the ship along the locus of her centre of gravity. It must be noted, however, that the head-reach traveled by a ship when turning is shorter than that traveled by the ship proceding on a straight course. This discrepancy of head-reach is mainly caused by the appearance of a drag component of the centrifugal force due to ship turning. The paper is concerned with pointing out the noticeable discrepancies between calculated and full-scale test results of these rather complicated crash-astern manoeuvres. The author proposes that the value of head-reach obtained from an official backing test should be corrected by considering the increment of effective hull resistance due to turning of the ship.
