abstract

To provide some data on the turning quality of ship., turning experim.ents have been carried out on'1/50 th scale free model of a certain cargo ship in 3 conditions of loading. I

The paper describes an investigation on the quantitative effect on the turning of ship by changing the trim condition. • i

The experimental results are summarized in Figs, 2, 4 arid 5. The tactical .diameter are increased 8 to 10 percentages by changing the trim 1 percentage afterward, arid the turning speed and yaw heel are decreased as comparatively as the' tactical diameter.
