For a training ship "Hiroshima-Maru", the captive model test which changed various heels was carried out to examine the effect of the ship's heel on hydrodynamic force characteristics and to clarify the mathematical model. The knowledge obtained in this study is as follows: The heel effect on rudder normal force is small. A remarkable change does not show a hull-rudder interference coefficient according to heel angle. The heel effect on hull hydrodynamic forces differs in a positive and a negative domain of drift angle. Particularly, the heel effect on the hull linear derivatives is small, although the heel effect is remarkable in a domain of large drift angle. The heel effect on effective wake fraction in maneuvering motions is small to the extent that it can ignore. The tendency for a straighten flow coefficient to decrease when a heel is attached is seen.
