Question 690 Rules of the Road

The correct answer is A) It shall not impede the passage of any other vessel navigating within the channel or fairway. This is correct because under both the International and Inland Navigation Rules, a vessel navigating in a narrow channel or fairway must not impede the passage of any other vessel that can safely navigate only within that channel or fairway. The vessel shown in the illustration is the "burdened" vessel and must take early and substantial action to keep out of the way of other vessels. The other answer choices are incorrect. Choice B is wrong because the vessel does not show two balls. Choice C is incorrect because vessels are generally prohibited from anchoring in narrow channels or fairways. Choice D is wrong because the vessel shown is the "burdened" vessel, not the "stand-on" vessel.
