At 0600, you are entering the inbound leg of the traffic separation scheme at position LAT 36°59.2'N, LONG 75°47.6' W. Course is 250°T. At 0605, Cape Henry Light bears 249°T At 0610, Cape Henry Light bears 248°T At 0625, Cape Henry Light bears 247°T Based on this, you know you are __________.
• relative bearings changing over time and what that says about your track • the relationship between lighthouse bearing trend and set (sideways movement) due to current • how a decreasing or increasing bearing shows whether you’re being set to the right or left of your intended course
• Sketch your track line and the lighthouse on a simple diagram. As time goes on, are the bearings to the light shifting clockwise or counterclockwise? • Ask yourself: if you were exactly on your intended track with no current, what would you expect the bearings of the light to do as you go past it? • Think about whether the light appears to move forward or aft along your beam. Does that correspond to being pushed north or south relative to your intended inbound course?
• Carefully note whether the bearings to Cape Henry Light are increasing or decreasing over time. • Confirm on a chart: when inbound on about 250°T in that area, is north to your right-hand side or left-hand side? • Match the direction of the bearing change with whether your vessel is being set toward or away from the lighthouse’s side of your track.
