Navegando de noche, observamos una luz blanca y, algo más baja, en un lado de ella una luz roja y en el lado contrario otra de color verde. ¿De qué tipo de barco se trata?Sailing at night, we see a white light and, somewhat lower, a red light on one side of it and a green light on the other. What type of vessel is it?
Show the answer
Correct answer: b) A power-driven vessel seen from ahead.
Why it is correct
Seeing both sidelights means it is head-on. The higher white light is the masthead light of a power-driven vessel.
Why the others are not
- a) From astern only the stern light shows.
- c) An anchored vessel shows no sidelights.
- d) A trawler adds all-round green over white.
How to work it out in the exam
- Red and green together: it is head-on, so apply Rule 14.
