"The Shape of the Canoe"

I found great article about designing open canoes - "The Shape of the Canoe" written by John Winters (article at boatbuilding.com/article.php/ShapeoftheCanoe. I suppose most of, if not all, hull design principles presented by John applies to sailing canoes also...? Canoes designed by John (www.greenval.com) looks really cool. I did quick search and found quite many beautifully designed and modern kayak and canoe plans - but all plans and DIY kits of sailing canoes seems to look like 20-30 years old design. Hope to see some development in this area also.
