If you estimate 3° leeway due to northerly winds, which course will you steer per standard magnetic compass (psc) to make good 255°T?
• Leeway is the angle your vessel is pushed sideways by the wind, measured from your heading toward the direction you actually move • A northerly wind means the wind is coming from the north and blowing toward the south • To make good a desired true course, you must decide whether to steer left (smaller degrees) or right (larger degrees) to counter the leeway
• Draw or imagine your desired track of 255°T and an arrow showing wind coming from the north; which way will the vessel be set off that track? • If the wind is pushing you sideways, will your actual track end up with a larger or smaller true bearing than the heading you steer? • Should the course you steer be into the wind or away from the wind to keep your actual track on 255°T?
• Confirm whether leeway is applied by adding or subtracting degrees from the course you want to make good • Check whether the correct answer should be a course greater than 255°T or less than 255°T, based on the wind direction • Verify that the difference between the steered course and 255°T is 3°, matching the estimated leeway
