Nos encontramos en situación 36º 00,0′ N, 006º 00,0′ W, navegando al Ra = 138º. Sopla viento del este (E) que nos produce un abatimiento de 12º. Calcular el rumbo que realiza el barco afectado por el viento, sabiendo que la declinación magnética = 3º NW y el desvío de la aguja = –9º (menos).We are at 36º 00.0′ N, 006º 00.0′ W, on compass course 138º. An easterly wind gives 12º of leeway. Calculate the course made by the boat under the wind, given magnetic variation = 3º NW and compass deviation = –9º (minus).
Show the answer
Correct answer: b) 138º
Why it is correct
Total correction −12º, true 126º. The east wind comes from port and pushes to starboard: 126º + 12º = 138º.
Why the others are not
- a) It does not match the working.
- c) It does not match the working.
- d) It does not match the working.
How to work it out in the exam
- True = compass + total correction.
- Wind to port: add leeway. To starboard: subtract it.
