🔍 Key Concepts

• Set and drift definitions and how they relate to your DR and fix • Relationship between course steered (090°T), DR position, and an error that is 0.5 mile east of DR • Difference between direction of current (named for where it is going) and the direction of your track line

💭 Think About

• Sketch your intended track along 090°T and then mark where the fix would be if it is 0.5 mile east of the DR. Which side of the track is that? • Ask yourself: if the vessel is ending up east of where you expected, in which direction must the current be setting the vessel? • Think about whether the 0.5 mile difference in 30 minutes represents a rate in knots, and if so, how you would calculate that rate.

✅ Before You Answer

• Be clear about what east of the DR means on a chart (right-hand side when looking north). • Confirm that drift in knots = distance (NM) off track / time (hours) if the displacement is due to current alone. • Verify that a current’s name describes the direction it is flowing toward, not where it comes from.
