Anybody here concerned about flying in a plane built from the same brittle stuff that your masts are made out of and break frequently?

Would you rather use an aluminium or a carbon mast?

Have'nt broken a carbon skinny yet been using them for 5 years.Though i do get a new one every 2 seasons.

Nothing wrong with carbon masts if they're designed properly. Hope it's the same for airplanes, especially if I'm up in one.

The problem I am refering to is consistency of manufacure. I know every mast maker will be testiment to the fact that they have had bad batches over time. It's either an inconsistency in the fabric or it's difficult to maintain tolerances in the manufacturing processes but all have had problems over the years.

I've worked with a few Aerospace fitters (Plane mechanics) who have told me of the hoops they have to jump through.

The QA for manufacturing proceedures on Planes makes our the manufacturing of our masts look like it's done by knidergarden children.

There was also an episode on Beyond 200 (I think) quite a few years back when these planes were on the drawing board showing the laminates and the testing which they did on them and it was all superior.

Just remember if gravity wants to get extra freindly with a plane Fire is the last of your worries

Yep I once flew in china and there was no safety instructions so I asked the crew why. They said we crash - you die !!

If my life depended on it - mmmmm let me think for a moment.

If every mast failure represented a catastophic failure in air I would go aluminium - but its not a apt analogy - mast arn't designed with lose of life in mind - else the would probably be solid or some sort of honeycomb kevlar core.

I just wouldn't be one of the first inline for the new flights.

"The problem is all the unknowns that are being introduced and then explained away as if there is no problem," said Vince Weldon, a former Boeing engineer, in an interview to be broadcast as part of Rather's report.

Well, how is this any different to a new anti-cancer drug? Any innovation comes with unknowns- there's always risks associated with unknowns. The regulators and manufactures have to do their best to mitigate those risks based on all available knowledge.

Who knows? There's always a good story for a journo from ex-employees.

Soo true. was going to make the same point. If Boeing or Airbus made masts they would last for at least 10yrs but would have been tested ultrasonically, microscopically, x-rayed (maybe not but you get the point). Likely they last 10yrs or more and probably cost a few grand. Full lifetime warranty and you'd probably have to have then certified every year by certified mast mechanic as well as a 500hour inspection to boot.
The difference is like shooting a feature film via your $50 camera-phone from T-Moble on location in Compton,CA (think Boyz inda Hood) vs the production crew from Lord of the Rings shooting and Imax feature in New Zealand and Antarctica...x10.

Think you may have misjudged that one, (possibly more like 50 years) my wife and I have between us 5 70% carbon masts all 10 years old. Admittedly my wife doesn't stress her masts too much, but I've had mine stuck in the reef, tip first with board dangling in mid air, a few times. No point asking what they are, Killwell stopped making matrix 5s years ago more's the pity. (I need a shorter masts now)

Did I say 10, my "5" key and "1" key must have swapped partners while I wasn't looking.

Decrepid,I noticed that Hot Sails Hot Rods are made in partnership(whatever thats supposed to mean)with KILWELL FIBERTUBE.
Got one,seems OK,priced well.

That's very interesting fullmoon, cause Phil Smith (Bugs) was the instigator of that mast when he was in NZ working with Hot Sails. I'm sure he'll be interested to hear about it.
Are they standard diameter or a tad smaller??

You can get dodgy metal batches to, or dodgy build quality, or Heat which changes the properties of the metal introducing week spots. Carbon is probably just as safe if designed properly. Also, u seen what happens when aluminium catches fire :D

Yes.....first time I read it, I thought "Hmmm....has Africa had some sort of high tech upgrade??"
