Transverse frame calculation

mala, please don't start. You are not up the task as you allready proven.
You are not designer nor boatbuilder. Your post about keel was the dfemonstration of your great ignorance.
Daniel

 

Of course you didn't found an expert, You don't know what is an expert
Judjing someone by his gallery is quite a ***** act.
Daniel

 

Don't try this game. you wrong and far to ingnorant.
Could you please have the courtesy to present yourself and tell us a little more about yourself and where you live.
Until now you seams more a spamer. And spamer are not allowed.
Be polite

When one receives a huge pile of drawings form a designer, it's a warning that the design is horrendously complicated, for which there is no excuse in a small sailing craft.
It's far easier for a designer to draw in a lot of irrellevant bits and pieces, than it is to build them, and its often an excuse for a designer charging a horrendous price for plans.
I've simplified my boats to the point where it takes very few drawings to give the builder all the info he needs. The same has been said by people using the origami boatbuilding section iin my book. The method is so simple, that there is not much more to be said about it.

Anyone asking about how much torure a big origami boat can take should read the book 'No Fixed Address" by Clive Hammill. ISBN 0-6204-0787-8
It's in the Vancouver Island Library system. It's a great read , and reminds me of Moitessier's writing. If it is not in your local library, then suggest they order it in.
In the last pages, he describes pounding on rocks in a huge swell for 6 days, before being pulled off in huge swell, being lifted and dropped repeatedlly on the rocks before breaking clear. No damage
.
She is the biggest origami boat I've ever personally built 47 ft overall with 1/4 inch plate. I ended up going the physio therapist with a bad back for a while after. Now I only build to 36 feet. It's much easier on the back. Lifiting gear would have helped.

You describe the inside of the keel as a hinge?
Take a length of piano hinge. Try opening and closing it while holding a curve in it. Then think of the curved 3/16th hull plate and the curved 1/4 inch sides of the keel, along with the curved edges of the 3/16th tank top, all comming together and full welded, and you get an idea of the strength given by many curves all comming together., fully welded. I don't expect anyone who has problems visualizing things in 3D to comprehend this, but those "two dimensional only " people shouldn't be designing shapes as complex ,and having as many curves as a sailing hull.
As the aft end of the twin keels are under the pilot house floor, you can extend it as high as you please ,without getting in the way of floor space, or cluttering the inside of the tank.. Lately I have been lapping the angle stiffeners onto the back of the tank, which takes it to the centreline. As I have pointed out ,the aft end of the keels are the points which need the greatest strength.

Is someone suggesting we completly forget the lessons of the Sleavin family tragedy and thus allow others to suffer the same fate, while making it a taboo to suggest doing anything different , to avoid it repeating itself?
Had they been in any steel boat ,they would have survived, as the Gringo incident clearly shows. Their boat was smaller than the Gringo, so the dammage would have probably been less.

 

I have no doubt that the people posting here have a huge amount of experience and ability. Unfortunately, the ability to see stresses in 3D , and the ability to look at the entire hull and decks of a sailing hull, and their interconnection , instead of seeing and thinking in two dimensional only, is, sadly, not possessed by some. They can only see each component as standing alone, not attached to, nor supported by others, nor by their shape. This has held back the development of small steel sailing craft, for far too long.

 

Its not rocket science, its nowhere even close to that. Its just common sense, something that seems quite uncommon unfortunately.[/QUOTE]

Right on! I have been trying to explain the structural basics, in comon sense terms, to people who seem to have none.
Its like speaking Chinese to a unlilingual Greek , or vise versa.

 

The real reason people want me to quit is so their quarter million dollar boats don't have to compete with my 30,000 dollar boats , so their 3,000 dollar roler furlers don't have to compete with my $200 dollar furlers, so their $40 blocks don' have to compete with my $2 blocks , so their $1400 composting heads don't have to compete with my $80 composter heads so their $200 lavac heads dont have to compete with my $20 lavac Type heads , so their $10,000 water makers dont have rom to compete wioth my $1,000 watermakers etc etc . the list goes on.
Reminds me of the time when George Forman was world heavyweight champ. Many heavyweights were constantly saying "He should retire for his health." What they realy were thinking is "He should retire and stop making us youngsters look bad ", or "He should retire before I'm forced to fight him and get my as kickd by an old guy." Same game , diferent time, different subject .
Relax guys . My clients could never afford your prices, so we are not competing for the same market anyway.

 

Common sense says you are unfortunately an ignorant neophyte.
Even the carpenters are having a laugh at your expense at my work. A builder knows more about basic beam common sense intuitively than you. And you hold yourself out as an educator

SO you think that you can re-educate highly trained and very experienced experts in their fields to BS boat-building BS style.

To come up with 10 completely wrong assumptions from your extracted posts in this thread alone would take a first year mechanics student a few minutes, it's all either grossly incorrect or grossly confused facts .

It's megalomania to suggest you know best while completely unable to showing some ballpark calculation . It's just bedtime stories claiming it's all fantastically strong because of magic curves, yes it's smoke and mirrors to cover up your gross incompetence.

All the pro's here work think and see 3D structures with ease, it's actually you that's lacking this understanding completely. How can you remain so thick skulled. You don't even have lines and other basic hull data, so you can't even be shown the 3D tools at work on your crappy design assumptions. That would show you very clearly.

Or maybe you do understand it since you have a problem admitting you are wrong.

You even come up with an excuse for selling crappy design sketches as building plans, and then imply that people who draw detailed plans are con artists. Boy what clientelle are you actually marketing to. Certainly not an experienced builder, they'd have you in court in seconds.

Of course if the poor sods you sell this con too can't understand how to put it together from your 'plans' then you get a job building the boat. So there is some real vested interest in not having plans a beginner can follow easily.


You really appear to be morally corrupt on every front, and you are playing with peoples investments and even lives. I'd like to show you too that a large frameless hull would collapse and be lost, from a simple wave impact, not even a ship impact. I know one of your clients was trying to get lines off the hull to give to the designer If they have now would be a good time to give them to me so I can shown you some real 3D ...accurate too.

And that 57 foot you reffer to a post or 3 back wasn't your design, and it was framed, it was just the plating first framing second technique that lets you claim origami......right? Then it's another false implication for the masses.

 

This debate has drasticaly increased book and plans sales for me. Thanks for the oportunity to answer these questions.

 

Brent this is insane. call it what you want, YOU CAN"T SPIN IT, since you desiged it.
Nobody should built one of your boat. You are to dangerous.
Seeing your design detail, I don't beleive one word of everything you said about your cruise in very dangerous see, and pounding without any major issue.
It is simply not true, I am sorry, but it is all in your head.
You forget one thing: other people, me included, sail. But we don't brag about. Braging as you do, it is bacause you lie.
The proof? your design detail. It all in the detail, it reveal the personality.
Ignorant and refusing top learn.
And letting your customer adding floors and frames show how careless you are.
Plaese don't wrote that insanity:

It is just an other mental diarrhea. I built and design to many boat to take crap like that. It's insulting.
And by the way your sea stories are also quite insulting.
Daniel

 

Good luck, you could not have me in mind when posting that nonsense. A quarter million US$ would not buy my 38 footers, and I do not build sailing boats.

Bad luck, you must have meant me, because I was the only (active) builder contradicting your drivel here, as far as I can remember.

No, Brent, Murielle convinced me already, It is better to see you die in your own **** than banning you!

Btw, I had a nice mail showing me some of your "drawings" (you call them plans in your ad.s), shocking.

Would you mind if I post them here? (you know nobody can copy them to make a boat, so, there would be no risk of loosing your income)

On top of that I got a comment:

....interesting Brent! A nice fu(king scam.......

and thanks for this comment, coming with a negative rep! Don´t fear to sign it next time.

Richard

 

This is a pretty good lie. Some of your customer are running away.
Don't be fool by your own mirror.
I use the internet, don't forget, and I find interresting things.
Don't take us for stupid.
Daniel

 

Hmmm,

this was another comment I received by mail:

I too love the initials btw...................

And this is the "design" a prospective buyer gets when he is dumb enough to buy your scam.

(now that we know you are improving your business with our kindly assistance we must not fear that you argue when we help a bit with free ad´s)

My best regards
Richard

 

So, you again, refuse to anwser any questions about your poor detailing and your poor financial records of misappropriation of costs that any dictator would be proud of

Ahh, ok, like this you mean.



This is perfect for you and those that wish to waste money.

What is so difficult about showing clarity like this?



I can just image you going into a car show room, and asking to buy a car. Salesman says we have a nice new #36...oh..oh..can i see it? No says the salesman, give me your money, i'll show you child like dwgs what it may look like, which have no meaning to what it is really like and then you can build it yourself...so it is cheap for you, because ours are shinny and clean and obviously too expensive for a person dressed the way you are.

I get it now....the nice snake oil con
