This paper describes the test results of on-line and real-time analysis of maneuvering motion of a fishing boat by a digital autopilot. The analysis due to model reference adaptive system (MRAS) method, which is implemented in the digital autopilot, is compared with those due to linear equation method (L.E.M.) and least square method (L.S.M.) which are usually used. Conclusions are: 1) The Nomoto's steering qualities indices T and K obtained by MRAS, are much coincident with those obtained by L.S.M. for 5deg. or 10deg. zig-zag maneuvering tests. 2) Ship maneuvering motion of 5deg. zig-zag test are simulated with respect to T and K estimated by analysis methods, and they are found to be similar to each others, in spite of differences in T and K according to analysis methods.
