Origami steel yacht construction

[dskira]

But Watson it is not the point I asked to Brent.
To know the GM he has to have the full weight calculation, plus the full waterline inertia calculation.
He never ever provided that, but stated that I was not a naval architect in one of his post, and stated that every boat not designed by him are a waste of time and money (I make a short cut of his claim, perhaps not the exact words)
I have the right to challenge him. Since he put the thread on this level, as a professional, I expected him to answer on the same level.
HE NEVER ANSWERED AND JUST TRYED TO DIVERT THE THREAD BY STATING A VERY DANGEROUS NON SENCE.
Therefore been a danger, been wrong, been not able to design a boat, been a danger for people who bought his plan, and by is own doing he should go away from this forum.
Amateurs (are we are not all amateurs in the real sense of the term, from the Latin Amar, meaning Love and I am a lover of boat like certainly all of us in this forum) are the most welcome, and I LEARN from them, yes I learn every day from all of you.
But crooks who use the forum to sell a book and plans are a danger for the boat society.
Disguising the marketing behind a wall of lie is not what we expect.
I consider and its proven that Bren Swain is a crook and a fake.
I challenged him, he had all the time to respond, he never did.
I don't see what he bring to the forum beside lies and innuendo.
I never ever tried to sell ONE plan, or to tell people what to do EVER.
I have the greatest respect for all of you, but a bad apple came, and yes I lost my temper with some of you, even with Jeff, and I publicly apologize for that and especially to Jeff, which after all we are his guest. I forget that for a while. Being in disagreement with him, didn't authorise me to have been rude, which I felt I was.
I don't lost my temper anymore with Brent, since no lost temper is necessary against him.
Just asking ONE question he can't answer.

Whatever.

I think we have a misunderstanding here. I was talking about a hypothetical Brent boat not your personal boat. "That tall" was referring to the bermuda rig as designed. You can't replace a stayed mast with a freestanding one of the same height, of the same material, with the same strength without massively increasing the weight. I know you CAN build a junk rig with a steel mast, obviously it would have to be much shorter than a bermuda rig with equivalent area.

Have you seen the analogies Brent uses?

No wardd, I would say the opposite!

The method, which is not BS´s method btw., is and was discussed here to the very end and in general consensus being a valid one to some extend.

The person is making these discussions senseless by drivelling them down to anecdotal tales and stories.

Not the method was criticized, but the false arguments, lies and exaggerations of the person promoting it. Boatbuilders, Homebuilders, Welders, Boilermakers, Na´s, Designers, Engineers and even skilled Amateurs, have proven the person wrong, not the system. And ALL received insults, attacks and negative feedback.

When one is claiming to be the only one on earth with a valid recipe (which in itself is already insane), he has to proove all others wrong, or leave the scene.

In this case, BS has attacked everyone asking for the proof. He instead, has proven on many, many occasions that he himself does not understand the religion he promotes.
It is therefore mute to discuss the religion any further in his presence.

Ban the person, then lets go ahead discussing methods!

That was a nice example how to circumnavigate the main topic here Jeff.

As mentioned several times now, the pointage is not the problem we have with BS!
Revenue and value of our Forum was the point, as Ad Hoc so eloquently expressed.

Richard

btw, I am not bothered, just felt it was unnecessary.

I agree, and please read my post they goes in your direction. Did you see ONE technical answer from Brent on 101 naval architecture, the BM? the most important point, without a proper answer no dialogue is possible.
that the problem Wardd, Brent put the thread personally so it is IMPOSSIBLE to have a real discussion.
Not because of us Wardd, not us. That the sickness of Brent, to make belief.
He do the same with his plan (I can prove it since he do not know what is BM) he sell paper, DANGEROUS paper. For money.
Would you like to have a friend drowning because of a bad design. No of course.
Plenty of good people wanted to exchange with him, read the thread with attention, he refused flatly.
Don't put the fault on us, it's wrong, sorry

Please I urge you to read my last post, and you will understand why I think Brent do not belong here. It is very technical, nothing to do with anything else.
And make no mistake, HE HIS NOT AN UNDERDOG. To bee one you have to know your 101 and from that go on a different path.
Some naval architect are underdog and they are real and knowledgeable.
Putting Brent at this level is insulting for them.
(I worked for one of these real genius)
Daniel
PS added: (I said BM which is Buoyancy/transverse metacenter, it is GM gravity/transverse metacenter, but this is not important since the former has to be calculated to have the latter, thing that Brent do not know and never answered. If he answered correctly he had to gave automatically the BM before finding is GM. So my difference is mote since linked. Just to be precise)

Some of us can only give negative feedback so often. (:

System limits us, wants us to spread the love around etc.

You have good point. Looking back what the man has to say..
"I pulled the hull" 581 times (including quotes)

A few decades ago when pc:s were young breed there was a program called "BS generator". It produced speeches of any subject you wanted to without any meaning in the sentences.. but it sounded like it had some sense.. if you wasn't really listening..

We have a similar system here Teddy.

Just open a thread with the terms "metal", "steel", or "boatbuilding methods" in the title!

Immediately the "BS generator" generates meaningless content!

Try!

Ive read a fair bit of this forum (not all, I have a life!)
Can anyone tell me where this started from-in that how many (or any) of BS's vessels/designs have sunk or suffered structural failure?
Where did this start from?

I understand you have a life!
The point is not the failure (but it will come to that unfortunately for the people on the boat) the point is the following if you read all the thread:
Brent said that his design are the only one valuable, all other are a waste of time and money.
He said naval architect are over charging clients for they own profit.
So we ask him to prove that.
I asked him SEVERAL TIME to tell us what is the GM of his boat and ALL the calculation backing the number.
HE NEVER ANSWERED THAT. THE 101 OF YACHT DESIGN.
Without knowing that you do not know your design thus what you are selling.
But boy he insulted us personally, to avoid any technical confrontation.
And when he answer let say about steel, he goes on for so long with terms chosen in Wikipedia, that for an uninformed person can be very confusing, since he explain...........nothing. That is the technique that make you ask your question.
HE DOESN'T NOT KNOW EVEN WHAT IS A GM, THEREFORE HE PUT HIS CLIENTS IN DANGER TO SUDDENLY DIE OF CAPSIZING AND PUT THEM AT RISK SINCE THEY DON'T KNOW THE PRODUCT THEY BUY.
he pretend that his boat are safe at 170 degree. It is not possible, and do not back this number. And he can't since he doesn't know the first rule of stability, the GM.
He deceives and lie.
And that is the point.
He attack personally the professionals to hide his shortcoming.
Since he is payed for his plan, he commit fraud, and should not be here.
WE OFFERS to help him countless of time, each time he returned with insult, innuendos and stories about his cruising.

So that is not an answer for a man who declare that his design are the only one valuable, ALL the other design are bad and the yachting comunity is a bunch of crooks. (I don't exaggerate, just read the posts)

I DO NOT KNOW WHY HE IS ALLOWED TO BE HERE.

I am like you, I have a life. But I don't like to be taken hostage by someone who jump on you anytime you post on steel related, or tell lies on his products, and use the forum as a propaganda platform for selling his product.

I want to be comfortable in the forum. And yes to exchange ideas on the forum is part of my life.

One reverend Jones is enough, we know the end.

Hi Robo, I was wondering about the same thing, so I looked up Brent Swain's boats track record. Couldn't find a single case where catastrophic failure had occurred with the exception on one fellow who didn't build to the designers specs. All of the owner/builders of Brent's boats who responded were happy with the boat although some had move onto bigger ones. Two of them told me that they really appreciated his coming and helping tack it together, and his enthusiasm was an inspiration to help them finish. There are few of his boats available second hand and they do not depreciate any more than any other boat. I recommend you buy his book even if you decide to build some one else’s plan there is some good common sense advice for a novice builder.
Having said that do read the post and the criticisms. Some of the points brought up are legitimate and you should consider them if you are going to build a Bent Swain designs. It would take very little to address their concerns.

Hi Brent,

I was waiting for you to post today.

It looks smth like a boat, and it might be a boat if constructed properly, but nobody knows the limits bcs it's not designed at all.. just pulled together as BS says.

[Brent Swain]

The bottom line on any design is how she sails and have there been any serious failures. Anything else is far lss relevant. Best get this info from those who have built and sailed them, not from armchair experts who have never sailed , built nor even seen one.
Luck never lasts 30 years and hundreds of boats, in an unbroken streak. That's not luck, it's fact. It over rides theoretical calculations; with reality.If structural problems were even a remote likelihood , they would have happened many times over the last 30 years, not waited till now, or some future date. It doesn't work that way.
As I have pointed out, any hard chine hull can be built using origami methods, with huge savings in time and money .I have often encouraged those who seek a different hull than I want to design, to go ahead with another design. I only design what I believe in. I give them all the technical help I can , free of charge.
The more happy people there are with steel boats, including the not so rich, the better off all steel boat builders. We have different clientel but common interests.The more people who move to steel, the more will want to follow them.
Older methods obviously work, with a much greater effort and time, and potential for distortion, but origami is the next logical step along metal boat evolution.
Steel has, as yet huge unreaized potential for small ocean cruisers .
Lets keep the evolution advancing, and not get stuck at any one point..

Brent was supported and encouraged initially on this site. But he started making some statements that were wrong with respect to just how structures work. He claimed that he had a novel and creative new technique that made transverse frames unnecessary in boats up to 60 feet.

Unfortunately it was based on a very serious misunderstanding of structural principles.

He made numerous attacks on existing and proper design and build procedures for people not adopting his method. When we tried to point out he was actually more than a little misinformed he didn't respond very sensibly.

A subsequent look at his construction 'plans' for his 36 footer and a look at his construction methods revealed a lot of very poor detail and techniques that could be and should be easily improved. In fact his construction techniques are very poor.

Brent doesn't hold with discussion of improving the design even though there are some abysmal design flaws that may even lead to the hull being breached at some stage.

His justification for the design involves deceptive claims of what his designs have endured. Tales that come from Brent with a glimmer of truth but a lot of creative spin added for marketing purposes. None of the inflated anecdotes come from a third party but only from Brent.

What is really concerning is that he has fudged stability and clearly lied about how that had been derived, his vessels will have nothing like the stability he claims, of all the issues this is a particularly serious one.

His response to having any of his errors pointed out was not to accept and discuss them and move on, but to try and twist distort and mud sling.

So he slowly dug a hole in which he now resides.

And a 26 31 or 36 foot steel boat will be very forgiving of design and construction flaws. An alloy one won't, neither will a larger vessel.

If you want to do a statistical analysis then you need to involve more vessels than just Brent's. Class rules have already done this and suggest absolute minimums that should be adhered to. To this end a lot of Brent boats have been constructed properly with extra framing and good fabrication. Those boats will be more durable in the long run.
