🔍 Key Concepts

• Running fix (R-fix) theory: how and why you advance an earlier line of position (LOP) to a later time • Difference between dead reckoning (DR) track and track made good (TMG) when current is present • How set and drift of current affect the advancement of an LOP between two bearings taken at different times

💭 Think About

• Ask yourself: between the first and second bearing times, did the vessel actually follow its DR track, or was its motion over the ground changed by current? • Think about what you are really advancing: are you advancing the ship’s intended course and speed, or the actual motion over the ground between the two bearings? • Which choice uses the vessel’s true movement over the ground between observations, rather than just changing one bearing or just changing speed?

✅ Before You Answer

• Be clear on the definition of course and speed made good (over the ground) versus ordered course and speed through the water • Check which option correctly uses the vessel’s actual movement between the two bearing times to advance the first LOP • Eliminate any option that suggests ignoring current or treating current as a simple speed change without considering its effect on the ground track

Question 1 of 20

You are plotting a running fix in an area where there is a determinable current. How should this current be treated in determining the position?

The set should be applied to the second bearing.

The course and speed made good should be determined and used to advance the LOP.

The drift should be added to the ship's speed.

The current should be ignored.
