Hello John,

Sorry it took so long to get a reply to you. This section, "Draft Placement" is referring to a sail that has already been constructed and has shape already designed into it. Jim says widening the seam makes the sail flatter, this is because the stitches that have been removed in order to increase the overlap, to the point that there is a consistent seam overlap throughout the sail, results in a flatter sail. Alternatively, if you remove seams and decrease the overlap of that section, relatively speaking, it is increasing the difference in overlap compared to the section that the overlap was not altered. 

Hope this helps!
