Coastal Skipper and Yachtmaster Quiz · Chartwork and passage planning
You want a water track of 250°T. The wind is from the south and you expect 10° of leeway. What course do you steer?
Seen from above, north at the top. A yacht is shown as a round position mark. A gold arrow labelled water track wanted, 250°T, leads away from her. The wind blows from the south, on to her port side. Caption: leeway 10°.
Show the answer
240°T. Leeway is allowed for by pointing up into the wind. The southerly wind will push her to the north of her heading, so steer 10° south of the track you want: 240°T. Drawing a quick sketch with the wind arrow on it stops you applying it the wrong way.
