Navegando en demanda del Estrecho de Gibraltar, a HRB=0600, en situación l: 35º10’N y L: 006º35’W, con velocidad 12 nudos, se da Rumbo Loxodrómico a un punto (P) situado en l: 35º50’N y L: 006º10’W, tomando al mismo tiempo azimut a la estrella Polar (supuesta en el Polo) Za= -007º. Calcular el Rumbo de aguja y distancia al Punto P:Bound for the Strait of Gibraltar, at ship’s clock 0600, at l: 35º10’N and L: 006º35’W, speed 12 knots, we set a rhumb line course for a point (P) at l: 35º50’N and L: 006º10’W, taking at the same time an azimuth of Polaris (taken as at the Pole) of -007º. Calculate the compass course and distance to Point P:
Show the answer
Correct answer: b) Ra=020º. D= 45’
Why it is correct
Δlat = 40′ N. Departure = 20.4′ E. True 027º, 45 miles. Azimuth −7º gives total correction +7º, so compass 020º.
Why the others are not
- a) That is the true course.
- c) The distance does not match.
- d) Both parts are false.
How to work it out in the exam
- Course and distance first, correction afterwards.
