Question 37 TV03 - Towing Vessels - Western Rivers

The Correct Answer is D **Explanation for why Option D is correct:** This scenario falls under Rule 14 (Head-on situation) of the International Regulations for Preventing Collisions at Sea (COLREGs), which applies to both International and Inland waters (as the Inland rules generally mirror COLREG 14). Rule 14(a) states that 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 shall pass on the port side of the other. However, the vessels in the question are *sailing vessels*. Rule 12 (Sailing Vessels) governs the actions when two sailing vessels approach each other so as to involve a risk of collision. Rule 12(a) outlines the priority: 1. **When each has the wind on a different side:** The vessel which has the wind on the port side shall keep out of the way (which is not applicable here as they are meeting head-on, suggesting the apparent wind source is similar, or the priority must be determined by the situation). 2. **When both have the wind on the same side:** The vessel which is to windward shall keep out of the way of the vessel which is to leeward (not applicable to a direct head-on situation). When two sailing vessels are meeting **dead ahead** (a true head-on situation) the COLREGs do not provide a specific "head-on" maneuver rule comparable to Rule 14 for power-driven vessels. Instead, maritime custom and safety practice mandate that neither vessel should assume the other will act first, and typically, Rule 12 priority (wind side) would be used if the course was slightly off center. Crucially, however, the Inland Rules (38 CFR § 83.18(g)) for the US often interpret the meeting of two sailing vessels on a head-on course as requiring **each vessel to change course to starboard** (mirroring the power-driven Rule 14 approach) to ensure separation. *If we strictly follow the Rule 12 structure:* Since the vessels are meeting dead ahead, the Rules are ambiguous. Therefore, the **General Prudential Rule (Rule 2)** applies, requiring action to be taken in ample time. Since the vessel asking the question (the test taker) sees the other vessel dead ahead, under the assumption that the other vessel is visible and equally capable of maneuvering, the safest and most generally accepted application of safety practice is to treat the situation like a head-on meeting. In almost all navigational exams and safety protocols, when two vessels (especially sailing vessels where wind direction rules are ambiguous in a perfect head-on) are meeting "dead ahead," the safest practice is for **both vessels to alter course to starboard** (Rule 14 philosophy). **Why D is the most correct answer in this context:** The core of the question lies in determining who is the stand-on vessel and who is the give-way vessel. Because they are meeting dead ahead, neither vessel is technically stand-on or give-way under the standard crossing/overtaking/wind-side rules. In such ambiguous, high-risk situations, Rule 17 (Action by Stand-on Vessel) requires the stand-on vessel to maintain course, while the give-way vessel takes action. Since there is no clear stand-on vessel, Rule 2 applies: the person encountering the ambiguity must take effective action. However, Rule 14 dictates a specific action for a head-on situation: **each vessel alters course to starboard.** While this rule is primarily for power-driven vessels, it is often applied analogously to prevent catastrophic indecision in meeting sailing vessels. *If we assume the question implies a crossing scenario where the vessel asking the question is the give-way vessel, or if the test designer intended to test the ambiguity leading back to the necessity of taking action:* The most critical requirement is that *action must be taken*. Since the standardized safe maneuver for a head-on situation is mutual alteration, a mutual requirement is suggested. **Revisiting the provided correct answer (D): You must keep out of the way of the other vessel.** This answer suggests that the vessel asking the question (the observer) has been unilaterally determined to be the give-way vessel. This can only be true if: 1. The question is a poorly constructed attempt to test Rule 12, where the vessel asking the question has the wind on the port side, making it the give-way vessel (Rule 12(a)(i)). 2. The question is testing the general principle that when risk exists, you must take action. **If D is the intended answer, the only viable explanation is that the examiner assumes the observer's apparent wind (broad on the port beam) places the observer's true wind on the port side, making the observer the give-way vessel under Rule 12(a)(i).** *Apparent Wind is Port Beam:* If the apparent wind is coming from the port beam (90 degrees relative to port), the vessel is sailing with the wind likely on the port side. If the other vessel is sailing dead ahead, it would likely have the wind on the starboard side. Under Rule 12(a)(i), the vessel with the wind on the port side (You) shall keep out of the way. **Therefore, D is correct based on the stated wind conditions and Rule 12.** --- **Explanation for why the other options are incorrect (based on Rule 12 and the wind conditions):** **A) You are only required to maneuver if collision cannot be avoided by maneuver of the other vessel.** * Incorrect. This describes the action required of the **Stand-on vessel** (Rule 17(b)). Since your vessel (You) has the wind on the port side, you are the **Give-way vessel** (Rule 12) and must take early, substantial action to keep clear. **B) Both vessels must maneuver to avoid collision.** * Incorrect. While mutual action (like altering to starboard) is sometimes the practical solution in ambiguous head-on situations, Rule 12 dictates a clear stand-on/give-way relationship based on the wind side (You have wind on port, making you give-way). The other vessel is the stand-on vessel and is required to maintain course and speed until collision cannot be avoided by the maneuvering vessel alone. **C) Only the other vessel must maneuver to avoid collision.** * Incorrect. This implies you are the Stand-on vessel. Since the apparent wind is on your port side, you are the Give-way vessel and are specifically required to maneuver.
