On BD.net they spoke lovingly of Lloyds Rules and ABYC while stating that one doesnt even consider the strength added by curves, while the other considers curves to give a maximum increase in strength of 15%. That is like claiming that a square oxygen bottle need only be 15% thicker to have the same strength as a round one! What a crock!
On that site, all but one of the people ridiculing what I have been doing, had almost zero experience in steel boat buiding, and the one who had some, had only limited coastal cruising experience. When asked he was th eonly one who responded.The rest were silent, indicating zero. Everyone in history who has come up with a new and better way of doing things has been ridiculed . Copernicus, Galileo, Columbus, Da Vinci , etc were all ridiculed by lesser men. The guy who suggested, in the1840s, that doctors should wash their hands after handling corpses, before getting involved in childbirth, was ridiculed for the rest of his life. So I am in good company. The only way to avoid ever getting ridiculed is to never come up with anything new, nor challenge in any way how things are being done, which is ,sadly ,how many people avoid ridicule. I prefer to leave such cowardice to lesser souls.
There are a dozen experienced yacht designers/naval architects/engineers several pro boatbuilders experienced in steel and numerous amateurs including coded welders with more knowledge than you, who either built or are building their own steel boats. They all universally condemned your ignorance and your hubris.
All class societies allow for curvature in effective thickness. As they allow a chine , deck edge cabin side etc to be counted as a girder. You donít seem to get this. They count all these things and still require transverse structures. And thatís based on thorough analysis, the problem with thin shells ( boat hulls) is that they are thin relative to curvature and buckle easily. The amount of thickness you can reduce for curvature is carefully calculated relative to buckling criteria. What external pressure will start to collapse the hull. When you build to class rules thatís inherent in the scantling requirements. If you custom design you should be able to state the head of water the structure will stand.
Even your own client feedback runs counter to your made up engineering. Here Tom who made the mistake of building to your plans isnít too happy with your engineering. To quote Tom's massage to you again which you simply ignored :
ďCase and point my plans on the 26 showed no cabin beams or longs in the cabin and I questioned you on it and you stated it didn't need any because the camber of the roof gave it great strength. Why is it that after it was all welded up I could walk on the roof and rock up on the ball of my feet and bow in the roof and bulge out the cabin sides at the same time? Also what would happen if I had left it that way and took a big wave over the top?"
Tom ditched his BS design sold it and bought proper plans from a reputable designer and has built a better designed steel boat.
So itís not only the knowledgeable designers and engineers who try to tell you have it wrong but your clients as well. And you still won't accept you have it wrong.
