Question 10 RVR04 - Master or Mate of LT 200 GRT

The Correct Answer is A **Explanation for Option A (fishing vessel):** The illustration D070RR likely depicts a vessel displaying three all-round lights arranged vertically: a green light over a white light over a green light (or similar configuration indicating a vessel "engaged in fishing, not trawling"). This specific arrangement of lights is prescribed by the International Regulations for Preventing Collisions at Sea (COLREGs), Rule 26 (Fishing Vessels). When a vessel is engaged in fishing (except trawling, which has a white over green light configuration), it is required to display these specific lights during darkness or restricted visibility to indicate its operational status and that it may be restricted in its ability to maneuver. Therefore, a **fishing vessel** (when actively engaged in fishing) is the type of vessel required to display the lights shown. This requirement applies to both International (COLREGs) and Inland rules. **Explanation for Other Options:** * **B) motorboat:** A motorboat (vessel underway power-driven) typically displays side lights, a stern light, and an masthead light (or masthead lights, depending on size). It does not display the specialized vertical arrangement of green/white/green all-round lights associated with fishing. * **C) sailboat:** A sailboat (vessel under sail) typically displays side lights and a stern light. It may optionally display all-round red over green lights at the top of the mast. It does not display the green/white/green vertical arrangement of all-round lights specific to fishing. * **D) pilot boat:** A pilot boat, when engaged in pilotage duties, displays two all-round lights: white over red (W-R). It does not display the green/white/green vertical arrangement of all-round lights specific to fishing.
