Thought I'd have a go at sailmaking but I'm a bit confused by a couple of points in the rules.
1) Width Measurement. The sail measurement diagrams show that the 'widths' are measured between the 1/4, 1/2 & 3/4 points on the leech and the nearest point on the luff. Simple enough but how do you find the 1/4, 1/2 & 3/4 points on the leech? Since the leech has a significant curve, do you have to measure round this curve, as that is a difficult to do in advance.
2) Leech Radius. The wording of J.6 is confusing to me. I think it's saying that you can have angles (or radii less
