This paper focuses on an analysis of a questionnaire survey regarding ULCV masthead lights as a means for determining LOA for ocean-going deck officers and coast guard officers. The contents of the questionnaire survey investigate ① The difference between the estimated ULCV LOA by naked eye observation of masthead lights and the actual ULCV’s LOA ② The effects of illuminating side passage lights as an aid to estimating ULCV LOA ③ The amendment of regulations relating to the ULCV’s legal lights (masthead lights, side lights, stern light, etc.).
Analysis of the results suggest that ① Respondents were not able to estimate the ULCV LOA by naked eye observation of the masthead lights ② Respondents were able to estimate the actual ULCV LOA by observing the illuminating side passage lights case, and ③ Respondents gave negative responses concerning the necessity of amending the regulations.
After a background review of this issue, this paper will analyze the data from the questionnaire results, and finally discuss conclusions and offer some suggestions for measures to correct any problems, as well as directions for future research.
