The boat had its first outing in Marseille and looks gorgeous. Unfortunately there are no detailed pictures yet other than these here http:/
The conditions in Marseille were difficult, but it showed enough potential in its first race (untuned) to generate alot of interest (and orders) from some top sailors.

Now, THAT's NICE! <img src=

I'm almost afraid to ask, how much?
I have been told that it costs
ready to sail
from US$ 19850 (from the boat yard in Switzerland) depending on how you want it finished. That could vary slightly.

There is a new development linked to this A-cat.
Here a quote from the CQ (cat quarterly) magazine :
**************
The new design makes use of the new revolutionary material Tilinium. The name is a combination of
Titanium
and
Aluminium
. It combines the better proporties of these materials with some that are normally associated with carbon fibres.
Because of the mix, Tilinium has three times the
strength to weight ratio
of aluminium and betters carbon laminate by about 50 %. It is more resistant to corrosion and degradation then the other named materials. It also has an extremely good fatigue resistance. The aluminium part allows this material to be extruded, with the titanium compound adding stiffness and strength and allowing a thinner wall thicknesses.
However none of these properties is actually the reason for its use in this new design. The properties that were of interest were actually the fact that this new and very exclusive material is now seen as far more fashionable then carbon laminate, something that is amplified by the fact that it is even MORE expensive as carbon laminate.
The builder feels that these selling points give him an undeniable advantage over the competition in a cat scene were the use of laminates like carbon and kevlar has become quite ordinary. Stock traders and .com millionairs are increasingly unwilling to invest 20.000 in a product that doesn't
Ooooh
and
Aaahh
the lesser fortunate sailors on the beach anymore. The builder expects this new material to quickly replace carbon laminate as the supreme false idol of modern cat sailors while its high cost will keep it well out of reach of the lesser designs like the FAD boats.

What is that, and where can I get it?
Part of a group of materials known in engineering circles as unobtanium, usually a mythical material with some or all properties that make it superior to other materials. However it can rarely be sourced or used practically.
Or more normaly a commonly used material given a new name to make it sound like it belongs to the group of materials known as unobtanium.
Does the article say what they use it for?

Are we being spoofed? <img src=

I googled for
tilinium
and the only reference I could find was
A description of an episode of a Science fiction show called Battlestar Galactica

No, no. Cat Quarterly's genuine: http:/

Since we are on the topic of metal,
Anybody heard of 'AlBeMet' metal?
A combi of Aluminum and Beryllium? Stong and not heavy!? I am trying to get more info. I don't think Ive been 'had' here...
You're not looking very hard:
AlBeMet® is a metal matrix composite, consisting of separate phases of pure aluminum and pure beryllium. This gives AlBeMet® a synergistic combination of the toughness, ductility and machinability of aluminum, combined with all the great properties of beryllium.
E Materials are available as E20 and E60, with beryllium metal and 20% or 60% beryllium oxide (BeO) by volume, respectively. E Materials were designed to take advantage of the superior thermal dissipation capabilities of beryllium metal and beryllium oxide ceramic material for electronics heat sink applications. These materials can be selected according to their coefficient of thermal expansion to maximize their compatibility with the electronic substrate.

Get your wallet out.
Well engineers have already succeeded at marrying aluminium and ceramics into a new material called glare. So why shouldn't it be possible ?

Be careful of the toxicity of an aluminum/beryllium alloy. Be sure to get a materials data sheet for that type of alloy. Different alloys have different levels of toxicity but I am guessing that one will require special precautions to cut or grind.
As an alternative take a look at aluminum matrix metals, M2 for example.
In general be real careful with exotic materials or materials not commonly used in manufacturing. In many cases there is a good reason they are not used.
I hate to keep saying this over and over but you only have to sit and wait for the medical people to go over the instrument reading trying to decide if you are going to die or not to be very respectful of the concept of toxic materials.
Carl, are you speaking about a experience you made yourself? Would you share the story, to drive the lesson home?
Myself, I have been to lax around WEST epoxy and sandpaper, but nothing a decent respirator dont stop..

I have experience with aluminium impregnated with carbon fibres, this is also used for the gudgeon pins of Nascars, I believe its just been banned from F1.
Same weight as Al, same stiffness as steel.

Grob,
Now THAT's interesting
Do you have a link to more info ?
Can this material be hot formed or will that destroy the bond c.q. fibres

There are two forms of beryllium-induced lung disease: acute and chronic. Acute berylliosis has a sudden, rapid onset and is characterized by severe inflammation of the lungs (pneumonitis), coughing, increasing breathlessness (dyspnea), and other associated symptoms and findings. In addition, in some individuals, the skin or the eyes may be affected. The more common, chronic form of the disease develops more slowly and, in some cases, may not become apparent for many years after initial beryllium exposure. Chronic berylliosis is characterized by the abnormal formation of inflammatory masses or nodules (granulomas) within certain tissues and organs and widespread scarring and thickening of deep lung tissues (interstitial pulmonary fibrosis). Although granuloma development primarily affects the lungs, it may also occur within other bodily tissues and organs, such as the skin and underlying (subcutaneous) tissues or the liver. In individuals with chronic berylliosis, associated symptoms and findings often include dry coughing, fatigue, weight loss, chest pain, and increasing shortness of breath.
Nasty stuff - if you inhale it.
Doesnt carbon and aluminum swap electrons? Wouldnt this combo degrade quickly in a marine enironment?
Can you engineer a design that would reduce the loads to the point you don't need exotic materials? That sounds cheaper... But not as sexy as Unobtainium
SPEAKING OF toxic materials, I just heard that Russian spy who died was poisoned by an exotic material (Polonium 210??) made from Bismuth exposed to neutrons. not sure if I heard it right, but one milligram is more than enough to kill...
So all that cloak and daggar stuff isn't all fiction... <img src=

Year and years ago I designed a beryllium heat sink for some space hardware. A simple metal block, machined and then pickled.
We had a safety review and were required to do all the work in a special machining station with containment and filtration. To make long story short, I was standing outside when suddenly dust started blowing out. It took about 2 hours to determine it was just
dust
kicked up by a cooling fan. It was a very long scary 2 hours. Plus I was wet from being washed down.
That was scary but not really dangerous. We knew it was hazardous and had 2 levels of containment plus filtration masks. The real danger is when you don't have a clue. The best example is cutting edge aerospace where they were working with brand new materials. There are a lot of stories from 1950-1960's of technicians dying from strange illnesses after working on secret projects. The SR71 and Be-Al for example. More probable for sailors are the people who coat their lungs while spray painting IMRON without a respirator, cleaning toxic materials off your hands with solvents that are absorbed by the skin or the time the by-product of curing paint killed all the insect life in my garage. (Or that neat surplus or stolen stuff you bought on eBay)
Know what you are doing. I have enough friends that are sick right now.
Thank you Carl.

Decades ago I painted cars for a living. When it got to the point that I could TASTE enamel reducer when I got it on my hands, I found a new line of work.

The general term is matrix metal. High strength metallic crystals with melting points higher than aluminum are mixed with aluminum. Normally they use bromides, carbides and monocystals. Sometimes the price is reasonable. Specialized made some bicycles with M2 framses

I have a picture somewhere, I posted it on this forum once but I know that link no longer works.
Its quite specialised and is very expensive at the moment. But like all these things should get cheaper as volumes increase. I think it can be made in a number of ways, the hard part is getting the two materials to bond well. The way we have used it it is hot formed in a mold, a bit like sintering, to get the net shape and is then finish machined.
