🔍 Key Concepts

• Effect of set and drift on speed made good (SMG) and estimated time of arrival (ETA) • Converting engine speed through the water and current into a single ground speed along track • Time = Distance ÷ Speed and keeping track of minutes and tenths of an hour

💭 Think About

• First, think about how a current of 0.5 knot from 215°T will affect your progress along your intended track. Does it tend to help you, oppose you, or act mostly sideways? • Once you have a speed made good along your course, how do you convert that speed into time for the distance from your last known point to 0.5 mile south of buoy "W"? • Compare the time difference caused by current to the time you would have gotten with no current. Is the arrival a few minutes earlier or later?

✅ Before You Answer

• Be clear about the direction from which the current is setting (215°T) versus the direction toward which you are steering • Confirm your total distance to run over the ground from the previous question’s starting point to 0.5 mile south of buoy "W" • Recheck your unit conversions when turning decimal hours into minutes (e.g., 0.2 hr = 12 min, 0.1 hr = 6 min) so the final ETA time makes sense
