VESSEL TRANSITION: ITS EFFECTS UPON BASIC PERCEPTUAL JUDGEMENTS RELATIVE TO NAVIGATION
A study was conducted at NMRC, Kings Point employing the CAORF simulator in order to investigate the effects of transition in vessel size upon perceptual judgements of bearing, yaw, and change in rate of yaw. Experienced masters and pilots participated in these studies. Significant differences in the magnitude of error in estimating bearing were found for masters experienced on less than or equal to 30,000 DWT tankers when their judgements were compared to bearing estimtes on the bridge of a simulated 250,000 DWT tanker. Estimation of yaw was relatively accurate, however, longer temporal delays in detection of yaw was found for both masters and pilots onboard the 250,000 DWT tanker as compared to the 30,000 DWT tanker. Differences between masters and pilots were dramatically apparent in terms of estimating rate of change of yaw with the pilots making judgements more accurately and with less temporal delay in detection than masters. Since basic perceptual information necessary for making navigation decisions is distorted as a result of vessel transition, these results apply directly to the necessity for transition training and have implications for promoting vessel transition endorsements.
