I find Brent's Origami process fascinating and would really like to watch one of the hulls being folded into shape. Many of his points such as welding chainplates, cleats & stanchions down make a lot of sense. One of his boats would certainly seem to be a good choice for serious voyaging - the security of steel can't be denied. I'd also be interested in some info on the weight of his boats - that frameless monocoque construction has to save a bunch of weight.
Having said that, I DO wish he'd dial back the utilitarianism a notch or two and increase the "yacht" factor by a corresponding amount.
They weigh about the same as framed boats but the true saving is in time and thus money, faireness greatly enhanced , zero filler needed. By the thicker plating it allows for the same weight, exponentially more resistant to distortion, and the greatly increased resistance to holing. Thicker plate also gives one a lot more forgivenes to corrosion. I've seen many boats which were a writeoff, but would have had decades left had the plate been thicker. Framing and lighter plate does nothing to reduce these problems.
The "Yacht factor" is basically the "dainty, flimsy and fragile look" factor. I find that if it looks dainty fragile and flimsy, it probably is. I refuse to design a boat dainty fragile and flimsy, the stakes are too high on ocean cruisers. Full time cruisers get the same rough treatment as workboats , and should thus be built more to workboat, funtional priorities. Experienced ocean cruisers are a lot more impressed by workboat priorities, than the dainty, flimsy, fragile "Yacht" look.
Read Moitessiers book "The Long Way" about a boat built to workboat priorites, which had far fewer problems and failures in a non stop 1 1/2 circumnavigations sail, rounding both the Cape of Good Hope and Cape Horn, than most boats built to "Yacht "priorities have in crossing the peaceful latitudes of the Pacific.
"Yachties were dismayed at the" Industrial " appearance of the round the world racing boats . Industrial works, decorative doesn't, in that kind of use.
