In the North Sea area, you sight a buoy showing a quick white light showing 6 flashes followed by one long flash at 15 second intervals. Which of the four topmarks in illustration D031NG below would be fitted to this buoy?
• This is an IALA cardinal buoy light characteristic: quick white, 6 flashes plus 1 long flash every 15 seconds • Each cardinal mark (North, East, South, West) has a unique combination of cone topmarks and light rhythm • Match the described light rhythm to the correct cardinal direction, then pick the drawing that matches that direction’s cone orientation
• Which cardinal direction uses a light rhythm of quick white 6 flashes plus 1 long flash (Q(6)+LFl) in a 15‑second period? • For that same cardinal direction, how are the two black cones arranged: both points up, both points down, points together, or bases together? • Looking at choices A–D, which option’s cone orientation exactly matches the standard topmark for that cardinal direction?
• Confirm from your buoyage reference which cardinal direction corresponds to Q(6)+LFl.15s (quick 6 plus one long). • Verify the orientation of the cones for each cardinal mark (North, East, South, West) – memorize the pattern before choosing. • Before you decide, ensure the chosen option shows two cones in the correct relative positions (top and bottom) with their points oriented as in the official diagram.
