It's a worthy project and article - please read. I post the photos here just to present the simple but efficient kind of hull that can be built in a "quick and dirty" fashion. Resourceful, inexpensive, and working with materials on hand - all the way of sustainability and the way we must go, as I understand it. We must work (gratefully) with what we've been given...
(The hull itself bears quite a resemblance my own old Voyager hull which, incidentally, sailed to windward respectably on it's hard chine.)
Thanks, Gary! For the info and for your excellent blog: Outrigger Sailing Canoes
