Being remarkably effective to reduce vibration and noise at the stern, a Highly Skewed Propeller (HSP) is reported, at the same time, to have conparatively less astern power than a Conventional Propeller (CP). By using Training Ship SEIUN MARU, full-scale experiments were carried out in order to evaluate the stopping ability and to consider the maneuvering of a ship with a HSP. In result, the following conclusions are obtained. (1) Stopping time and distance of the ship with a HSP is longer than that with a CP respectively. Differences in stopping time and distance are remarkable, especially in case of small |J_<s0>|(=U/(n・D)). (2) The crash astern performance of the ship with a HSP is considered quite similar to that of a ship with a CP. (3) As for the changing head motion in astern condition, there is no noticeable difference between both ships with a HSP and a CP. (4) During harbor maneuvering of a HSP ship, careful considerations should be given to its stopping characteristics. In other words, it is preferable to avoid excessive headway and to apply a little higher reversing propeller revolution than the nomal maneuvering condition of a CP ship.
