At 2020, what is the course to steer to enter the inbound lane of North Chesapeake Entrance traffic separation scheme if a northwesterly wind causes 3° of leeway?
• Traffic Separation Scheme (TSS) inbound lane alignment and charted course at North Chesapeake Entrance • Effect of a northwesterly wind on leeway and how it shifts your course to steer • Difference between course to steer and track/course made good when applying leeway corrections
• First, determine the charted course of the inbound lane at 2020 from the plotting sheet or chart – what is the desired track line without leeway? • With a northwesterly wind, from which side is the wind actually blowing relative to your intended track, and in which direction will it push your vessel? • Once you know which way you’re being pushed, should you steer more into the wind or away from it, and by how many degrees, to keep your vessel on the inbound lane track?
• Confirm you know that a northwesterly wind means the wind is coming from the northwest, not blowing toward it • Identify whether the leeway will set you to port or starboard of the intended track for this particular inbound course • Before picking an answer, apply the 3° leeway in the correct direction to the desired track and then match it to the closest pgc (per gyro compass) option provided
