Question 1 of 27070

Which error is NOT included in the term "current" when used in relation to a fix?

🔍 Key Concepts

• Meaning of set and drift of current when plotting a fix • Difference between environmental forces (wind, sea, current) and vessel or instrument errors • What navigators include under the broad term ‘current’ when comparing DR (dead reckoning) to an observed fix

💭 Think About

• When you compare your DR position with an observed fix, what kinds of effects are you trying to lump together under the word ‘current’? • Which option describes an error that you normally correct or account for before you ever plot DR and current effects? • Look at each choice: which one is clearly not an external force moving the vessel through the water, but instead an error in how direction is measured or applied?

✅ Before You Answer

• Identify which choices are external forces on the vessel’s motion versus internal/navigation errors • Recall that leeway (sideways motion due to wind) is commonly combined with current as a single ‘set and drift’ effect in practice • Check which option is a known, pre‑calculated correction that you would normally apply directly to the heading or course, not treat as ‘current’ when analyzing the fix
