Re: Pros and cons of steel sailboats

Jon:

Lots of composers composed for instruments they could not play. Mozart wrote a lot of horn concertos but he did not play the French horn. His buddy did.

Little Bobby Schumann could play the piano just fine. But there is a theory that he wrecked his hands using a contraption designed to stretch his finger reach. It is known that he did use this odd device. It's not clear if that's what lead to him stopping playing. But, he was a very weird guy. Ended up committing himself to an asylum where he eventually died. Some think he starved himself to death. Others think he died of syphilis.

Bobby's wife, Clara, was a very famous virtuoso in an age where it was very unusual for a woman to be a professional musician. She was also an accomplished composer when very few women were composers. Brahms lived with Bobby and Clara. Think of that.

Re: Pros and cons of steel sailboats

Maybe Mr. Schumann was attempting to build a steel yacht in his backyard?

Re: Pros and cons of steel sailboats

At the risk of being mundane ( above posts where delightful and reminds me Beethoven continued to compose after he lost his hearing and the Wizard of Bristol kept drawing after he was too old to sail) wish to return to frameless construction. Seems practical way to increase plate thickness while eliminating frames so total hull weight remains in "acceptable" limits. What I wonder is:
Is there a upper and lower limit to LOA where it just doesn't make sense?
Why don't we hear about this technique more in Aluminum construction? Being easier to bend and of significantly lighter weight seems LOA limitations are less likely to apply. Forget where but seem to remember a new sailboat manufacturer using a modification of this technique. Also wonder if a female mold could be constructed and with a hydraulic press using Al ( or possibly steel but more force involved) a production line of sailboats could be constructed at very reasonable cost.
Just wondering

Thanks Bob - I read your post as he couldn't PLAY, not just the piano. I doubt any of the composers of symphony music could play every instrument.

I, myself, personally intend to continue being outspoken and opinionated, intolerant of all fanatics, fools and ignoramuses, deeply suspicious of all those who have "found the answer" and on my bad days, downright rude.

Re: Pros and cons of steel sailboats

Out:
I think some of the French builders have tried way of making alu into a production material. They have done some very nice boats but there doesn't seem to be much of a market for them. I think today's sailor is wary of metal boats. GRP is pretty stable in a salt water environment.

I leave it to Brent to tell us what the lower limit LOA is for steel. I would guess that it would depend on the desgn and using Brent's method you could build a nice 11,000 lb.
30'er in steel, maybe less, if that was your material of choice. Brent's method opens the door to lighter steel building. I look forward to Brent's opinion on this.

Re: Pros and cons of steel sailboats

There are several French boat builders with a considerable production, I mean production boats. Aluminium is probably the material more used on French voyage boats and most of the French that want to voyage and do that on other type of boat do that mostly because aluminium boats are more expensive.

Of course, voyage boats are just a very small part of the global market and they are therefore a small minority even in France, but not in what regards boats designed with voyage in mind.

Re: Pros and cons of steel sailboats

One of the gadgets we got from Germany after the war (krupp?) was a huge hydraulic press I heard it was the worlds largest.They had used it to stamp out hulls of U boats. Victoria Machinery Depot used it for years making stuff for pulp and paper mills but never heard of more boat building by that method. Probably due to a resistance to try anything new. Back when I was in my explosives phase, I planed on pressing aluminum into a female concrete mold using overhead Amex charges.Fortunately for the fiber glass canoe and kayak industry I went on to ferro cement. The molds were just too heavy.

Re: Pros and cons of steel sailboats

From my limited understanding cost of Alu is tied to cost of electricity. Maybe as electricity cost fall in the future Alu construction in production runs will be more viable. Interesting post Len. Nothing new under the sun.

Re: Pros and cons of steel sailboats

Steve just built a Boreal 44. It's a boat I looked at before the Outbound. Very sound vessel beautifully executed. Admiral didn't like the feel of interior lay out so dropped off the list. I would have been pleased as punch. Hear what you say about Americans and metal. Knowing that and knowing the cost of the d-mn things when you think some sad day you won't be able to sail any longer metal boats become less attractive. Just easier to sell a boat in your home country when you have swallowed the anchor.
