Question 1
What is the standard length of one international nautical mile (NM), and why is nautical distance measured along the latitude scale rather than the longitude scale on a Mercator chart?
Correct Answer:
1,852 meters; one nautical mile equals one minute of latitude, which remains constant in physical distance, whereas longitude minutes shrink toward the poles
Question 2
What vertical chart datum is officially utilized by the Servicio Hidrográfico y Oceanográfico de la Armada (SHOA) for soundings (depths) on Chilean nautical charts?
Correct Answer:
The Nivel de Reducción de Sondas (NRS), a low-water reference chosen so that the real depth is normally at least the charted depth
Question 3
Which fundamental mathematical property makes the Mercator projection the standard choice for coastal navigational charts published by SHOA?
Correct Answer:
A straight line drawn between two points represents a line of constant compass heading (rhumb line or loxodrómica)
Question 4
A SHOA nautical chart's compass rose indicates a Magnetic Variation (dm) of 5° 30' E in the year 2018, with an annual variation of 6' East (+6'). What is the updated Magnetic Variation to use for navigation in 2026?
Correct Answer:
6° 18' E (+6.3°)
Question 5
A skipper plots a True Course (Rv) of 245° on a SHOA chart. If the local Magnetic Variation (dm) is 7° East (+7°), what is the corresponding Magnetic Course (Rm)?
Correct Answer:
238°
