Transverse frame calculation

Good posts from AdHoc which Brent should fully address.

Apex is the man of action putting to rest the demolition derby once and for all. Thanks Richard.

Yes frankly that's what I felt when I saw his plans. I agree the stringers are so slender they are insignificant. Brent argued they could be slender because they had magic properties ( always remaining in compression ). He aslo believes that the curved plate acts as full transverese support of the longitudinals thereby reducing the span!

Smoke and mirrors and statistics and misleading conduct is Brents MO.

Anybody considering building an origami hull should add a few thousand dollars to the plan cost and get a professional to finish the plans off properly. Brent could do this once and lift his game. But his ego won't let him deviate from the line in his book.

By now he could have achieved ISO compliance for free from forum advice.

He still could

 

Brent, shipbuilder use plans to built, not rendering.
If you can't explain with plans, don't bother.
Plans with details this is the fondation of the boatbuilding.
If you tell the builder: Oh wait, it is better in three dimension, he will call security to throw you out!
Plans Brent, plans like you show us. that is the reality.
Don't spin this one, you fail miserably.
You are what you are, an ignorant, and an arroguant. and quite dangerous. And yes it is difficult for you to understand plans.
You are playing with steel, you just have a little fun to weld in the worth condition for welding (but you don't know that), you don't care, since as I said long time ago, you are not a boatbuilder. Boatbuilding demand some morale attitude. Your lake of morale is unbeleivable.
You are a narcissiste.

Obviously you don't KNOW what is a floor.
Structural integrity? Yiou know what it means? No of course, no clue.
Thanks Brent, you are sinking a little more.
You are dangerous. Stop designing, promoting and building boat.
It will be better for your customers.

Richard,
I totally agree with you about the blames you have against Brent but I have to agree with Mike about the usefulness of letting Brent argue at his good will on this thread. This is only one of many boat forums that Brent uses to advertise himself, if he looses access here he will still keep spreading his word on other sites.
Brent will keep spitting on true marine professionals elsewhere and non will be there to counter his non sens. If he wants to keep critiquing naval architects and engineers, he best do it in there face. If wants to keep arguing, let him do. There is no better forum for it as no other forum offers as competent members on the subject as this one. The objective and structured argumentation that is being presented on this thread provides a reference that can be used by anyone from any other site and by people that may not have solid enough knowledge to structure an argumentation as it is being done here.
If Brents arguments were strong enough, he should be able to convince boat designing/building community or potential clients by referring to this thread, therefore benefit from keeping arguing here (it's all fair). If not....well...anyway, you know what way this thread will benefit so must as well let it be.

I find great that this has not turned into a brutal pissing match, it's what makes it such a great reference, not only as counter-BS tool but also for some interesting content. Yes, much of what Brent posts twitches the nerves, either because he is being rude, annoyingly repetative or following some strange logic but it's worth enduring to just get to the end of this by giving good responses to what he has to present.

cheers,
Murielle

 

No argument can stand against that. Thanks Murielle.

 

You sir are a gentleman.

I mentioned before I don't see why Brent is fighting this. In some ways his construction method is very clever. And he markets to a group of people who otherwise would not, or would not feel they could afford a boat. But with that said, he is definitely lacking some fundamental engineering. There are a few things he could do that I imagine wouldn't cost his designs anything more in material or money, but would increase their ship-worthiness dramatically. There is no reason at al he couldn't incorporate these things.

In fact it is fool hardy for him to maintain his orthodoxy not to.

Brent, I applaud your sincerity and effort, but, why not do the right thing and consult the forum, and have some of these guys who despite all the vitriol of the past would be more than willing to "help you" at no charge, to update your design.

Take it as an opportunity to grow, and update your book. Still keep the aspects that make your designs easy to build and unique, but modernize them.

I hope you take me up on this. As Mike Johns said; this is an opportunity to up your game.

Machiavelli once said, "Entrepreneurs are simply those who understand that there is little difference between obstacle and opportunity and are able to turn both to their advantage. "

Some of of us may seem adversarial, but I imagine most of them want to help and not hurt you. Stop and think about it for a while and capitalize on the opportunities these experts are offering you.

 

Hum, hum!

 

These people are no experts, just have a look at their galleries.

 

"These people are no experts, just have a look at their galleries."

...mala, you have unfortunately been a member here since July 2010, you have posted 8 posts, I may be wise for you to not say such things untill you have understood many of these pepole on this site, many certainly DO know what they are talking about, some, of course are armchair admirals and flash crap all over the place, but if you KNEW what is right and what is wrong in the boatbuilding game, you would realise immediately someone posts if they are full of **** or they know what the pointy end is called..


......and yes, there is quite a lot of crap in the galleries, I agree with that, but there are a few experts here that really are just that.

....my old moto was "we do not know what we do not know"....maybe I should go back to that one......

 

I am a newb to this forum. I am not a naval architect, or a naval engineer or even a boat builder. But I did go to school for physics. My main focus's have been computational fluid dynamics, FEA, and designing aparati. Professionally I have had 2 careers. One in the entertainment and live event industry, and the other as a tinker/inventor/fabricator. I don't pretend to be an expert on boats, but I do know a few things about engineering, materials, mechanics, etc etc.

You told me to look at people's galleries, most people don't even have one. But all that is mute. Because Brent doesn't have a basic understanding of the engineering and physics involved. It doesn't matter how many miles he has sailed in a boat, or how many he has built. The fact it it doesn't even matter that it is a boat except that a boat experiences some unique forces that would be wise to be well advised of. The things that Brent is missing is the same if he were building bridges, buildings, or bicycles. Sure you can guess your way thru things, but that is no substitute for foresight in engineering, not for a boat, not for anything.

If you want to call out other people on this forum, have at it. But ad hominem observations get us nowhere. In this case the emperor has no clothes on, and it doesn't matter who is calling spades what they really are. I won't fly a helicopter with any pilot who can't explain dynamic lift or the conservation of angular momentum to me, nor would I buy a boat from any architect/designer/builder if they couldn't explain to me the engineering decisions they made. Its not rocket science, its nowhere even close to that. Its just common sense, something that seems quite uncommon unfortunately.

 

I think you had better understand about the grades of steel and what the grades mean first before you attempt to contribute.

PS....you could put up the material properties of Switz cheese if you like. No matter how you spread it, shape it, it is still Switz cheese. Same for steel...what its yield strength is, has nothing to do with its shape. Try again Brent...oppss...Mala

 

Then we are so lucky to have you, you imply that you are the judge the jury the executioner and the Word. I look forward to your posts and the lofty standards they will adhere to mala !

So what do you think about Brent's almost total lack of basic engineering knowledge ? Do you think he could scale that 36 to 60 feet, for example, and produce a robust vessel without significant frame modification. I'm curious where you stand in a sensible discussion.

And I'm curious as to what pictures you'd like to see in a gallery that would ensure that you could recognize a professional when you look there?

We do know amongst us who is a poser and who is for real. You would be quite surprised to find the level of achievement that some here have achieved. Both builders and designers, fabricators and even people starting on a learning curve can contribute quite a lot at times.

If you haven't recognized any expert yet it might possibly be that your glasses need a polish
