The signaling angle for open flame signaling is what degree?

• A. 15
• B. 30
• C. 45
• D. 60

Answer: (C)

Open flame signaling works best when the flame is held at a height and angle that makes it easy to see from a distance while staying clear of deck obstructions. A mid-range angle of 45 degrees provides that balance: it elevates the signal enough so it isn’t blocked by rails or the hull, yet it isn’t so steep that the flame becomes hard to spot or unstable in breeze. Angles much lower can be hidden by the vessel or smoke, and angles much higher don’t improve visibility and can be harder to spot at typical signaling distances. So 45 degrees is the standard for reliable open flame signaling.
