You’re operating at night when you see a white light flashing this pattern: a short flash and brief dark interval, then a longer flash and a longer interval of darkness, repeated every 8 seconds. What is it?
The answer is: the white light is sending the morse code equivalent of the letter “A” which in the IALA-B system are used only on mid-channel and fairway buoys. You’re on the water at night and you see the lights below: an amber light that flashes once each second for three seconds and then is off for three seconds, indicates what? What are you looking at?
Port side of a submarine [on the surface], under way, making way. He is the stand-on vessel, you must give way. The flashing light sequence spells out in Morse code the letter “s” for submarine. This is prescribed in 72 COLREGS (Rule1[c] footnote). |
