Now that gives cause to ponder, aircraft thought to be light and unbreakable, Boeing comes to mind?????

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.

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.

Yeah. Check page 51 on this document.

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.

Yep I just read the e-mail from F1 Hooray! something on TV to watch, only problem is the hours which are a little inconvenient. :-) ...lew...

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

It's hard for me to get excited about the F1 cars after the wings came in. When the turbos took over, I quit caring.

But wasent it nice to see Kimi win? I don't like to see a "freshman" win the championship, it inflates their ego too much. :-) ...lew...

I liked it better when the driver sat up-right too. 1958 USA GP in Sebring Fla. Phill Hill in a BLUE Ferari along with Von Tripps etc. Anyone want to see the pix ? I put them on the computer back a while ago. ...lew...
