A method for critical target's position, the position at which collision is avoidable by give-way vessel's maneuver, has been developed. The method can be cosidered about trajectories were obtained using nonlinear maneuverability theory, error of estimated target's vector and passing conditions. The passing conditions are the minimum distance to keep between these two vessels for safety passing, and the time to spare for avoiding action. The critical target's positions were determined for various speed of vessel and different passing conditions. And the distribution of these positions around give-way vessel (critical position for give-way vessel), and the distribution of these positions around stand-on vessel (critical position for stand-on vessel) were shown. The difference of these two distributions showed that give-way vessel should take avoiding action not only before the critical position for give-way vessel but also before the critical position for stand-on vessel.
