Additional Lights
Fishing Vessels
When certain fishing vessels are engaged in some specified activities, they are to show additional light combinations. These are shown below. Since it is unlikely that you would encounter vessels engaged in these activities in the Strait of Georgia, you are not expected to know these light combinations for the course. They are provided for your information.
It should be enough to recognize the lights for engaged in fishing: green-over-white or red-over-white vertical all-round lights. Since you should always give way to vessels engaged in fishing, you should keep clear.
Trawling
Vessels
of 20 m or more in length when engaged in trawling, whether using demersal or pelagic gear, shall exhibit
(i) when shooting their nets: two white lights in a vertical line,
(ii) when hauling their nets: one white light over one red light in a vertical line,
(iii) when the net has come fast upon an obstruction: two red lights in a vertical line.
Each vessel of 20 m or more in length engaged in pair trawling shall exhibit
(i) by night, a searchlight directed forward and in the direction of the other vessel of the pair,
(ii) when shooting or hauling their nets or when their nets have come fast upon an obstruction, the lights prescribed in the paragraph above.
Purse Seiners
Vessels engaged
in fishing with purse seine gear may exhibit two yellow lights in a vertical line. These lights shall flash alternately every second and with equal light and occultation
duration. These lights may be exhibited only when the vessel is hampered by its fishing gear.
