Now that gives cause to ponder, aircraft thought to be light and

Lot's of people think that.
Aircraft are unbreakable only when opperated within prescribed limits.
Beyond that the are guar-on-teed to bust.

America's Cup racers have to be as light as possible for performance.
Looks like this one was just a bit TOO light.

So, there is such a thing as a boat designed to be too light.

Carbon fiber structures are very strong for their weight but are not
noted for graceful failure modes.

Yeah. And we tend to overestimate how strong carbon fiber is. On the
average, it's only 10% or so stronger than S-fiberglass. Its big advantage
over other composites is its stiffness, not its strength.

I think the hull of those boats gets changed fairly often (every few
years) trying to get better hydrodynamics. when you look at things
that way durability is a low priority if its only needing to stand up
to one or two seasons and wear and tear wont really be a factor

ac boats are designed to practically fall apart at the end of the last race
about 10' over the finish line. if not, then it was designed too strong and
heavy (read: slower).

long term durability is not one of the design constraints.

Ha! I had to look at that wreck for over a year. After they pulled it out of
Jamaica Bay they hauled the wreckage to a lot behind my office in Harrison,
NJ and just left it there after the inspection. Eventually it was taken out
to somewhere.

Watch formula one auto racing- when there's a shunt , there's CF shards
thrown all over hell and gone. Why they don't require a kevlar wrap to
contain the crap is beyond me though I suspect that the shedding of parts is
their way of shedding energy at the same time. BTW the f-1 season starts
this week. Despite the past several seasons being about as exciting as
watching kudzu grow, I'm still watching...sigh. Pat

I thought they *did* require a Kevlar wrap. They did in IRL, when I was
writing about it.

Pat, if last season wasn't exciting enough for you, you may need to seek
medical attention. I can't wait for Hamilton to kick Alonzo's butt well
and truly this year.

Yeah, BUT with the antics of alonso in the pits keeping hamilton away and
the espionage accusations being thrown about, I wanted to throw a brick
through the tv. That and the fact I lost my cable connect for the last 3
races of the season....sigh. I suppose I'm showing my age when I mention
that I liked f1 when they had the turbos, aspirated, v6-8-10-12 engines all
competing. sigh... Pat

I think the problem was related to the team losing their designer a few

Wings are still there, but turbos are out, along with (this year)
traction control and engine braking.

Ah yes, Mr. Excitement. In a red car. yawn.

Hamilton is the best thing to happen to F1 since Senna. He deserved the
championship, but the FIA penalty would n't let it happen anyway.
