Question 32 FCP01 - First Class Pilot

The Correct Answer is A. ### Explanation for Option A (Correct Answer) Option A, **not under command**, is correct because the illustration D084RR depicts a vessel exhibiting **two all-round red lights displayed vertically** where they can best be seen, with sidelights and a sternlight also visible. According to both the International Regulations for Preventing Collisions at Sea (COLREGs) Rule 27(a) and the U.S. Inland Rules, a vessel **not under command (NUC)** (i.e., a vessel that, through some exceptional circumstance, is unable to maneuver as required by the Rules and is therefore unable to keep out of the way of another vessel) must exhibit: 1. **Two all-round red lights in a vertical line** where they can best be seen. 2. When making way through the water, masthead lights, sidelights, and a sternlight (which are visible in the illustration). ### Explanation of Incorrect Options **B) showing improper lights:** This option is incorrect. The lights shown (two vertical all-round red lights plus running lights) are the *proper* lights required by the COLREGs/Inland Rules for a vessel that is not under command. **C) dredging:** This option is incorrect. A vessel engaged in **dredging or underwater operations** (a restricted in her ability to maneuver (RAM) activity under Rule 27(b)) exhibits specific lights indicating the operational status and the side on which it is safe or unsafe to pass. Specifically, it would show: * Three all-round lights in a vertical line: Red-White-Red (RAM signal). * Additionally, when dredging, it typically shows two all-round red lights vertically indicating the obstructed side and two all-round green lights vertically indicating the side on which another vessel may pass. The illustrated pattern is clearly not the dredging signal. **D) towing:** This option is incorrect. A vessel engaged in **towing** (Rule 24) exhibits two or three masthead lights in a vertical line (depending on the length of the tow), sidelights, and a sternlight. Crucially, it does **not** exhibit two vertical all-round red lights unless it is also restricted in its ability to maneuver or not under command. The primary signal for towing is the vertical masthead lights (white) and the towing light (yellow) above the sternlight.
