Vessel Constrained by her Draft
- E.
Vessel Aground
Correct Answer
D. Vessel Constrained by her DraftExplanation
The correct answer is "Vessel Constrained by her Draft." This means that the vessel is restricted in its ability to maneuver because it has a limited depth due to its draft. A vessel's draft refers to the distance between the waterline and the lowest point of the vessel's hull. When a vessel is constrained by its draft, it cannot navigate in areas where the water is too shallow for its draft, limiting its maneuverability.Rate this question:

- A.
Cylinder
- B.
Diamond
- C.
Cone
- D.
Star
Correct Answer
C. ConeExplanation
A vessel engaged in fishing, other than trawling, is required to exhibit two all-round lights in a vertical line, with the upper light being red and the lower light being white. Alternatively, the vessel can display a shape consisting of two cones with apexes together in a vertical line. Additionally, when there is outlying gear extending more than 150 meters horizontally from the vessel, the vessel must display an all-round white light or a cone pointing upwards in the direction of the gear. Therefore, the correct answer is "Cone" as it represents the required light or shape to be displayed in this situation.Rate this question:
