Abstract : This experiment was established to examine differences in ship handling performance of pilots transiting a narrow waterway on ships that exhibit distinctly different inherent maneuvering characteristics. The experiment was conducted using sixteen experienced pilots on four ships (all 80,000 DWT tankers) which exhibited distinctly different inherent maneuvering characteristics. The statistical analyses showed that with practically every ship performance measure that was employed, a significant ship-difference was found; with the most unstable vessel showing poorer performance and the stable vessel indicating better results. Three distinct areas of the test scenario (which was based on the SNAME ABC Harbor) were found to cause major difficulties; namely, when turb effects and wind current sets were additive. It was determined, thorough structured debriefing, that the pilots were aware of the differences in transit performance difficulty. In spite of this, the experiment ihas shown that with comparable ship familiarization on each of the new vessels, the piloted performance on ships having different inherent maneuvering characteristics was variable.
