Question 8 GLI02 - Mate of Unlimited Tonnage

The Correct Answer is A ### Explanation of why Option A is Correct **A) Two power-driven vessels meeting head-on** This situation is governed by Rule 14 (Head-on Situation). Rule 14 explicitly requires **both vessels** to take action simultaneously: > "When two power-driven vessels are meeting on reciprocal or nearly reciprocal courses so as to involve risk of collision each shall **alter her course to starboard** so that each may pass on the port side of the other." Because the Rule uses the word "each," it mandates a simultaneous, reciprocal change of course by both vessels. This is the only scenario listed where the Rules require simultaneous maneuvers from the very beginning of the avoidance action. *** ### Explanation of why the other options are Incorrect **B) Two power-driven vessels crossing when it is apparent to the stand-on vessel that the give-way vessel is not taking appropriate action** This situation is covered by Rule 15 (Crossing Situation) and Rule 17 (Action by Stand-on Vessel). * Initially, the give-way vessel is solely required to change course (Rule 15). The stand-on vessel must maintain course and speed (Rule 17(a)(i)). * When the stand-on vessel realizes the give-way vessel has failed to act, Rule 17(b) states the stand-on vessel *may* take action. * The stand-on vessel *shall* take action only when collision cannot be avoided by the give-way vessel's action alone (Rule 17(a)(ii)). While the stand-on vessel eventually *may* or *must* act, the rule does not require **both vessels** to take action simultaneously as a defined maneuver. The stand-on vessel only acts because the give-way vessel failed to fulfill its initial mandate. **C) Two sailing vessels crossing with the wind on the same side** This situation is governed by Rule 12 (Sailing Vessels). When two sailing vessels have the wind on the same side, the one which is to windward (upwind) shall keep out of the way of the one which is to leeward (downwind). Therefore, only the **windward vessel** (give-way) is required to change course, and the leeward vessel (stand-on) must maintain course and speed. **D) All of the above** Since options B and C do not require both vessels to change course as the primary maneuver dictated by the Rule, option D is incorrect.
