Editing Entry angle

You need to measure the angle some distance away from the centerline to avoid the local stem shape. We recommend drawing a line parallel to the centerline 10% of the maximum waterline beam (i.e., 20% of the half-breadth) off center, then take the tangent of the waterplane at that point. This gives a repeatable, quantifiable, measurement and avoids all of the small insignificant local shape right at the bow.
