The Automatic Radar Plotting Aids (ARPA) should be equipped with all ships of 10,000 tons (gross tonnage) and upwords till 1989 on IMO's resolution. The users of ARPA have to understand the error of the data indicated by ARPA. Comparing the ARPA simulator and the ARPA on board the training ship (Oshima-Maru, 327 G.T.), the authors reported the error of data, the course and speed of targets, DCPA and TCPA, indicated by these two ARPAs, which are of the same type (JAS-800). And the four examples of the swap observed on board the ship are showed in this paper.
