I have a couple old masts that I still use going on 12 years, and I'm getting nervous about their stability.

I keep them both in bags and out of the sun when not in use.

Is there a way to tell when a mast is getting too old? or a life span that one should heed?

thanks

For me if they survive the first year they are proved. And good for 5years
then into reserve pile.
never had one for 12 years

The conditions and where you sail and how often all factors to consider

Side of waves and winter is a lot different than summer baffing
would not want to consider breaking a mast in the first
Would not even worry for the second
But that is for me

Also my experiance is newer sails are much better tune on new mast vs older
works the other way too old sails old masts seem to work better
Weird since masts have not change much in 10 years.

As said, if they last the first week of sailing, they should last quite a while. Most of mine are over 15 years, doing just fine.
If you tend to crash, listen to the previous poster religiously. I tend to stay dry for weeks at a time, so old masts work peachy keen....for me.
If I sail the coast, it's skinny's for me. All bay sailing get old standard mast since I'm a surfer can can paddle hours at a time.
Nobody without an X ray machine can predict the life of carbon masts. The breakages usually occur months or years before, a slight impact causing a weak spot in the fiber strands, only to break years or weeks later.

Agree completely. Waves, offshore winds, winter...I want newish carbon and uni. In summer I run the older stuff. Non-wave sailing I've kept masts up to eleven years, and then sold them cheap at the swapmeet.

cool thanks,

now that I've asked though, I've probably jinxed myself

(I'll still use this as an excuse to get some new masts)


thanks guys!

Photo of a 2004 Neil Pryde X5 (520) 85% carbon mast that unexpectedly broke a few days ago while cruising in 10-12KTS and flat water.

No pumping at the time and only light/moderate downhaul tension on a 9.8 Neil Pryde V8. Snapped cleanly right at the top cam above the boom and below the ferrule. That cam sits just above a minor wear spot left from another sail. Not a creak. Just a very loud snap and it was gone.

Mast appeared in good condition with minimal wear and fading. Never left rigged, stored indoors and in padded bag.

Sailed the exact same rig one time prior a few weeks ago. Powered up in about 15-20KTS and flat water. No indications of any pending failure. certainly not a thought that it could ever fail then or during that next lighter session.

Granted the X5 was 8 years old, it had what I would consider fairly light use and good care.

Swear I've had more N.P. mast failures in flat water than any other brand.

Even in my small one-man sampling, I've had masts and hourglasses snap like toothpicks on their first sessi0on, on a lake. I think your "newISH" caveat is important; get infant mortality out of the picture first in risky conditions.[/i]

I use PowerEx carbon RDM's. I have three of em. Bought the first one in 1992, so it's 20 years old, the last one I bought used in 1996 (It's probably a 93' model). They all work great, no plans to replace any of them, and I sail 20-60 days/year depending on how crappy the wind is in the midwest. Hard to break a skinny.

Smann,

Or you could call your brother who owns a windsurfing shop and he can take care of you!
