🔍 Key Concepts

• Effect of current on speed over ground (SOG) • Difference between speed through the water and speed over the ground • Using Time = Distance / Speed once you know your SOG

💭 Think About

• Think about a southerly current: is the water moving toward the south or coming from the south, and does that help or oppose your intended motion? • Once you decide if the current is helping or opposing, how does that change your effective speed over the ground compared to 6.5 knots? • After finding your new speed, how would that change the time needed to reach point A from the leg information given elsewhere in the problem?

✅ Before You Answer

• Be clear whether 6.5 knots is through the water or over the ground (typical exam assumption). • Decide if you should add or subtract 0.5 knots from 6.5 based on the direction of the current relative to your course. • Confirm you’re using consistent units (distance in nautical miles, speed in knots, time in hours/minutes) before estimating the ETA.
