That assumes your origami process is "better" than all other forms of boatbuilding when in fact it is only simpler. It also sacrifices almost all style for simplicity and practicality.

Many of us want more than the basics - "Give me the luxuries and I'll do without the necessities".

Re: Pros and cons of steel sailboats

"the most butt ugly boats imaginable."

Well you would be the expert there Brent.

I fidnd them less than attractive but far better looking than anything you haver done.
Care to post one of your that looks better?
I'll wait.
I'll go make some bread.

Re: Pros and cons of steel sailboats

Brent:
That was regarding the Islander Yachts series. You seem to want to apply it to everything I have done. Do I need to post more construction drawings? They will only succeed in making you feel more inadequate. Islander always did their own engineering. This is common with almost every high production boat builder. But how would you know BS? You have never designed a grp boat so by your own definition you would know nothing about the process. You have never designed a production yacht. You design backyard boats.

For the record our "basic" set plan provided to Islander would have included:
Hull lines
Keel lines
Ballast
Rudder lines
Deck lines
Interior layout
Interior inboard profiles
Interior joiner sections
tank layout
Prop shaft strut
Deck plan
Deck gear schedule
Deck details
Sail plan
Rigging plan.
Often a detail drawings or two or three of various areas.

Any owner of one of my design can buy a complete set of plan for their boat for around $500. On my bigger designs where there may be 20 or more sheets of drawings the cost will be around $1,000. I am selling plans to boat owners all the time.

And, once again Brent your reading comprehension fails you. I asked you to provide the quote where I said wood and grp boats wers stronger than steel boats.

Re: Pros and cons of steel sailboats

Hey Brent. While back I politely asked you a series of questions. You have yet to do so. Please go back and try. That's what threads are for.
By the way any ocean sailor knows jack lines and harnesses are what to count on to keep you on the boat. Life lines are to steady yourself so you don't fall.
By the way taking an outbound from bvi to Bahamas. Getting plane in am. Nicer than bcc this time of year. No leaks except off the stern at night. Bye now.

You find the Chatam 37 ad 40 ugly? Well I cannot say that I find them very beautiful but I normally don't find beautiful old hulls and these designs have many years, more than 20 if I am not wrong, but I find them remarkably modern for their time. The designer is really old and is semi-retired now but those designs continue to be built all over the world.

Certainly it is (was) a great design and those boats have navigated extensively, circumnavigated and sailed on the Arctic and Antarctic. Certainly the hulls work fine otherwise they would not have been built in so large numbers. The French are quite picky in what regards sailing performance and have a huge number of options in what regards boats and Nas.

In what regards aesthetics it is a more subjective matter but I would say that they are beautiful to many otherwise he would not have about 6000 boats of his design sailing the oceans and the Chatam series are one of the more popular series.

He seems to care a lot more regarding how his boats look than you, or at least is what seems to me.

Regards

Paulo

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.

Re: Pros and cons of steel sailboats

I find those boats very nice looking and obviously designed to sail well.
There is no comparison to what BS has to offer. It is day and night.

But, what would I know.
