Question 1

In the intercept method, Ho greater than Hc means…

Accepted Answer

You are closer to the body’s GP — move TOWARDS it along the azimuth — “Ho more, toward.” The intercept in minutes of arc is miles along the azimuth; the position line lies at right angles to it.

Question 2

The classic single-body ocean day is…

Accepted Answer

Morning sun line, noon latitude, afternoon sun line — run together like a coastal running fix — Position lines hours apart, advanced along the run between them and crossed — the running fix at ocean scale.

Question 3

A universal plotting sheet is…

Accepted Answer

A blank lat/long grid you scale for your latitude — chartwork where no harbour chart exists — Mid-ocean fixes need paper with a scale, not coastline. The sheet’s longitude scale is set by your latitude; position lines and fixes plot exactly as inshore.
