Well it was from your own words so I'm not sure where the charge of disinformation comes from.
by Brent Swain: "Given the tendency for the trailing edges of the twin keels to be driven up into the boat when they collide with a rock, and the fact that they are far enough back to be under the pilothouse floor in the 36, putting a 3/16th plate web across them would reinforce them without being in the way of anything. The top of this web could be T'd with a piece of ˝ inch by 4 inch flatbar, making it extremely strong."
You admitted that was your older design and that it needed improving which you did. I was using that to illustrate that your intuitive grasp of shaped based strength was wrong , that stiffness and buckling strength are not the same thing at all.
Here's your own post talking of scaling your frameless foldup:
by Brent Swain "My 26 is ten gauge hull plate, my 31, 36 and 40 are all 3/16th. I only suggested 3/8th for a 60 footer. "
You talked of another 65 footer once that you had some involvement with. But whether 60 or 65 the point is that the effort was made to show you that you cannot scale your frameless design to even close to 50 feet, the total length doesn't matter.
I had drawn the tank and specified the angle iron webs in that design by that time in the plans I sold them, which they ignored. The tops of the low aspect ratio keels on my 36 are 8 ft long. I have since seen them on that site , swooning over twin keelers which have about a foot of attachement to the hull, with a far higher aspect ratio.
How do you get a foot of attachement to a plastic hull ,with a far higher aspect ratio keel, to be stronger than 8 ft of attachement to a steel hull with a far lower aspect ratio keel?
You dont!( Mike the "Engineer?")
No Mike, with a track record like that ,I wouldn't want you "Engineering" any of my boats, any more that I would let a civil "engineer " do laser surgery on my eyes.
A friend posted several pictures of a couple of very successful origami 55 footers in aluminium on that site. One I last saw at Christmas Island after which he sailed back to BC in November. Jean Marc, the owner, has cruised enough miles in the Hecate straight area, year round to have done a circumnavigation, wiht zero structural problems .He loves sailing in full storms. Harvey , on the other origami 55 footer, cruises the west coast of Vancouver Island year round .
Completely demolishes your theory about them not being strong enough.
Here are some quotes from a letter Steve on Silas Crosby sent me from the Straits of Magellan
"I thought you should know that Silas Crosby is amoung the smaller boats sailing around , but it seems to cause us less worry that most boats down here .
The ability to get in very shallow and even dry out , or just touch at low tide, is a quality that most people, even here , do not have a clue about.
While avoiding ice chunks near the Pia Glacier, I hit a rock dead on at 3 knots . A shrug and carried on. Thanks for your helping me get here . Good boat, good design."
This completely demolishes Mikes theory about my boats not being strong enough. So who would you believe, someone who has sailed one of my boats from BC around Cape Horn, then home again via the western Aleutians , or some one who has never sailed on one , an armchair expert?
When the later claims to know more about a boat than the former, what is his credibility?
Take any Mike Johns design ( which I have never seen) and run thru Boat pass at full flood tide, at full throttle, and hit the big rock in the middle, and see how it makes out .As Mike implies, it will suffer no damage. I am sure he will fully warantee it against such dammage, so it wont cost you anything.
