During daylight, a vessel engaged in fishing must display which day signal?

• A. Two cones, apexes together
• B. One cone apex up
• C. A square flag
• D. A pair of red lights

Answer: (A)

During daylight, vessels engaged in fishing must clearly signal their activity so other mariners understand their situation and can give enough room. The standard day signal for fishing is two cones with their apexes touching. This arrangement is distinctive and recognized internationally to indicate fishing operations underway, helping to prevent collisions or entanglements with gear.

The other options don’t match this recognized daytime signal: a single cone apex up is not the fishing day shape; a square flag is not the stipulated fishing day signal; and a pair of red lights are used at night, not during daylight.
