Canadian Boating Practice Exam

If a vessel is trawling, what light configuration should it display?

1. An all-round green light above an all-round white light

2. Two all-round red lights in a vertical line

3. An all-round red light only

4. Normal lights for power-driven vessels

The correct answer is: An all-round green light above an all-round white light

When a vessel is trawling, it should display an all-round green light above an all-round white light. This is to indicate that the vessel is engaged in fishing activities and has nets in the water, alerting other vessels to give way and avoid potential collisions. Option B is incorrect because red lights are used to indicate a vessel's port (left) side, and two red lights in a vertical line would suggest that the vessel is steaming in that direction, which could lead to confusion. Option C is also incorrect because an all-round red light is used to indicate a vessel's presence, but a trawling vessel needs to display more specific lights to signal its activities. Option D is incorrect because normal lights for power-driven vessels do not provide enough information for other vessels to safely navigate around a trawling vessel.
