Question 265 Rules of the Road

The correct answer is B) it becomes apparent to her that the give-way vessel is not taking appropriate action. According to the International Regulations for Preventing Collisions at Sea (COLREGS), the stand-on vessel in a crossing situation is required to maintain its course and speed, unless it becomes apparent that the give-way vessel is not taking appropriate action to avoid the collision. At that point, the stand-on vessel is allowed to take action to avoid the collision. The other options are incorrect because: A) the distance between the vessels is not relevant in determining when the stand-on vessel can take action; C) the vessels being on a collision course is the condition that requires one of the vessels to take action, not the specific point when the stand-on vessel can act; and D) the relative speed of the vessels is also not a factor in determining when the stand-on vessel can take action.
