After seeing this quote from Brent in Bob's thread:
If you check the origamiboats site you will find origami boats of a wide variety of shapes, wide sterns ,narrow sterns ,canoe stern, wide bows, narrow bows, deep deadrise , shallow deadrise, single chines ,multi chines, radiused chines, etc etc. The one shape myth is just that, a myth, began by Michael Kasten who knows so little about the subject that he continues to decree impossible what we have been doing since 1980; perpetuated by those who have little or no understanding of origami boat building and no experience with it ,who have done nothing to educate themselves on the subject .
I was curious who this Kasten dude was. So I found some of his stuff. Sounds like a pretty reasonable guy with some pretty good experience. He has a good breakdown of the different metal building methods (including Origami) here:
Frames First or Plating First...?
And though his conclusion was that the origami method was interesting and clever, it was, at the end of the day, not really all that.
Even so, he doesn't seem to be pushing any "myths". As for the shape issue, all he says is pretty much what Brent says above. From Kasten's article...
In other words, variations to the hull shape are difficult and time consuming to create, so the vessels are limited to being either larger or smaller, fatter or more slender, taller or shorter, having more or less sheer, yet essentially the same in their general shape and appearance.
Further, it must be kept in mind that just as with the "pre-cut-plate" method, the "Folded-Plate" or Origami method is generally only applicable to the hull plating itself, and not to the keel, rudder, deck, superstructure, nor to the equipment, rig, joinery, systems, etc. In other words, though it should be accomplished as efficiently as possible, erecting the plating is only a small part of building the hull, and a very small part of the whole picture.
Sounds about right.
Some may wonder why I'm so interested in this. Well, it's pretty simple...I have a Degree in Architecture and worked in it for several years before I became an entrepreneur. I was always drawn to organic works by guys like the Saarinens, Utzon, etc. While I was in school, there was this "crazy dude" in our area who was building a house on a cliff overlooking a lake - completely out of steel...
I loved it. I was amazed by it. But I also understood that this thing was taking decades to get done...by a guy who knew exactly what he was doing.
So, I love the concept of origami boats. It's brilliant really. I just want to really, and honestly understand what it takes to do one, and do it well, by someone who knows little about the whole process (i.e. - the Wannabe Cruiser).
