In addition to starting near the favored end, you need to sail toward whatever racecourse features you think will help you the most tactically, and most immediately. This is, of course, one of the main reasons you got to the racecourse an hour before the start and tuned up and down a few times. During that time you should have gotten a feel for the conditions and started to notice what was important, relative to the wind and current. You will find that, most of the time, sailing in more wind and sailing toward the mark are the main factors that help you do well, especially in extreme cases. But sometimes other factors must be given priority, especially when the wind velocity and direction are steady. Sometimes, sailing toward favorable current or a geographic shift makes it to the top of your plan. And sometimes it’s a mix of factors that will end up working best, such as playing the shifts while working toward a side for favorable current.
