Nuestra embarcación navega enfilando Punta Carnero y Punta Europa y al tener Punta Almina con demora verdadera Sur nos situamos. Desde esta situación ponemos rumbo para pasar a 2 millas de Punta Carnero por el través de estribor. Se pide la situación de salida y el rumbo de aguja. Datos que conocemos: Corrección Total= 5º.Sailing along the Punta Carnero–Punta Europa leading line, you fix your position when Punta Almina bears due South true, then set course to pass 2 miles abeam to starboard of Punta Carnero (Ct = +5º). Find your start position and compass course:
Show the answer
Correct answer: a) 36º 8.2' N 005º 16.8' W. Ra: 225º.
Why it is correct
Extending the Punta Carnero–Punta Europa leading line NE intersects the meridian of Punta Almina (Dv = 180º, L = 005º 16.8′ W) at 36º 08.2′ N. From there, the tangent leaving Punta Carnero 2 miles to starboard (passing south of Carnero) has Rv = 230º, so Ra = 230º − 5º = 225º.
Why the others are not
- b) Does not match the fix at 36º 08.2′ N, 005º 16.8′ W and Ra = 230º − 5º = 225º.
- c) Does not match the fix at 36º 08.2′ N, 005º 16.8′ W and Ra = 230º − 5º = 225º.
- d) Does not match the fix at 36º 08.2′ N, 005º 16.8′ W and Ra = 230º − 5º = 225º.
How to work it out in the exam
- Intersect the Carnero–Europa alignment with the meridian of Punta Almina: 36º 08.2′ N, 005º 16.8′ W.
- Draw the tangent 2 miles SE of Punta Carnero (Rv = 230º) and subtract Ct = +5º: Ra = 225º.
