Abstract
Relations among various elements on vessel performance were statistically analyzed based on the Japanese Vessel Specifications, Specifications for Domestic Vessels in Japan (8,362 vessels, 1992) and ship maneuverability tests at sea (320 vessels). Relations of various elements are expressed by regressive linear equations of logarithms. Results are useful for statistically evaluating the maneuvering support system that estimates the dimensions of other vessels based on watch data. For example, the following equation represent the relation among the vessel length L, gross tonnage GT, sea speed V, and stopping distance, wherein σ denotes standard deviation. logGT=3.004logL-2.543, σ=0.254 (1) logV=0.368logL+0.400, σ=0.079 (2) logD_s=1.446logL+0.010, σ=0.016 (3)
