Have you ever been to Cabo? I have, and have walked on the beach where Joshua went ashore. Not a rock in sight, only sand . Again you distort the facts to suit your argument, just as your claim that Winston's boat had extra framing and plate thickness, compared to what I had designed. ÖÖÖ..
Brent if you were there, hadnít the hurricane stripped a lot of the sand from the beach and exposed reefs and boulders that ground up most of the boats washed ashore?
I have a cruising friend (Robert) that knew Moitessier well, Moitessier was very cavalier with Joshua with collisions and groundings thinking it was immune from damage. When Joshua went ashore he was actually in the bar and his boat was just anchored, he wrote some BS about being aboard !
As for Winston and construction, I didnít make that up the pro marine welder who inspected Winston said on BD net that she was built so. Easy to prove if you know the boat and owner so well they will have all the details.
Your drum skin theoryÖ..ÖÖÖ..
....isnít my drum skin theory itís the accumulated knowledge and science that makes engineering and itís the theory of plates and shells that any engineer anywhere will tell you exactly the same
Your problem in comprehending the principle, is you have a blind spot when it comes to the fact that the longitudinals are welded to the plate , fixed solid points. They are not floating free! Until you get that, you are mentally incapable of understanding the structural principles of the stiffness added by longitudinals. Ö..ÖÖÖ..
My problem adopting your engineering principles, thatís a good one from someone who claimed his boats had an AVS of 182 degrees !
I comprehend it all intuitively, thatís the problem, you donít, and I can show you that you donít, and have shown you that you donít.
And you constantly mix up diminutive steel tanks with proposed scaled up 60 foot frameless behemoths that simply wonít work. Thatís where you should be , addressing the silly claims that the design is intrinsically strong enough to scale to twice the size of the initial design you started with.
You also still havenít commented on the fact that other designs of yours rotated their keels because you misunderstood the structural adequacy. You lied when you said only the boat that tore holes after a high speed grounding suffered that fate didnít you !
So tell us Mike. How many steel boats to your own design have you built ?How many have been built ? What is the greatest number of decades you have been cruising in and maintaining any one of them? Why have I never encountered one of them ? How many of my boats have you seen, either cruising or being built No answer means NONE!
Iíve designed more that you, mainly one off custom designs for shipyards, nothing like the variety or number of sailboats of Bob Perry here but I also design other vessels like patrol boats, ships, floating docks if anyone wantís something designed. I'm not just a yacht designer I will design yachts when pushed or starving :-).
Iíve never seen a Brent boat ever, because the 200 you claim built around the world amounted to something like under 40 if I remember rightly from Tad Roberts estimates, and the majority are in Canada, none in Tasmania or I would have done an inclining test on it by now !.
