Just to add a question to this thread:  any comments on the durability of
carbon vs. epoxy vs. aluminum masts?  I broke two masts last year in the
shore break (both 2 piece, one epoxy, one aluminum), and I was relatively
happy that both were cheapies.  Would carbon be more or less likely to
snap?  Are one-piece masts more durable?

Thanks!

If possible, consult with whomever sold or recommended your sails, or
list your sails in here.

You should get a mast with not only the correct length and IMCS
ratings, but these days carbon masts come in a range of tapers, or
the diameter at the top, middle and bottom.  Your sails may or may not
work well with one of the more tapered or skinny masts. From what I
can see none of the manufacturers makes all tapers so that need will
limit or dictate whose mast is suitable.

I use only 2-piece masts because I prefer to store and transport them
inside my van.  They are otherwise mostly inferior to a one piece. The
2-piece is heavier, costs more, it may or may not have a funny
curve at the ferrule, and may have a built-in predisposition to
failing at the joint.  I have broken 2 carbon 2-piece masts over the
years.  Both were several years old, one broke at the joint (it split
from the joint upward) and the other broke between the boom and base.
So I guess my experiences on this last point are not weighted either
way.

1) No, a single is the way to go, if you don't mind hauling around 14' - 16'
of mast.  The new DynaFibers are supposed to have a stronger union than a
one piece, but that's the adverti***t - haven't heard actual reports.

2) I've found deals on NoLimitz for $125 - $150 (in Hood River).

Probably and yes.

Most of the surf-nazis that I know are running with epoxy, since
you don't really need the stiffness of a carbon in the waves anyhow.
Plus carbon is more brittle than epoxy so would be less likely to
bend as well in one of those spectacular over-the-falls crunchers,
and they are cheaper $$.

A one piece is a little bit lighter, a two piece is a little more
convenient.  Powerex is a good choice-bought one last year for around $
258.  We also bought a one piece Skinny for  $ 199 and like it but it
apparently does not work well for all sails.

Also have a Fiberspar 2 piece surf mast after breaking a World Cup but
have not used it yet.

I would recommend in buying a new mast over a used one.

Modern, big-name carbon masts 1) have no hard spot st the furrule,
2) weigh nor more (well, maybe the equivalent of a mouthful of
water) than a one-piece, 3) offer an almost infinite range of
bends/sizes/stiffnesses, 4) are as durable or more durable than
anything else you'd want to lift or maneuver, 5) are still
expensive, and 6) are worth every extra penny because of the lighter
weight and greate response.

Aluminum masts and surf mix like rotten eggs and ping pong, like jet
skis and windsurfers, like race sails and wave boards.Don't ever
take aluminum masts in breaking waves over, say, 10 centimeters
high. Maybe 12 cm, if you've very careful to keep the mast tip
pointed towards the next continent (not the one you're sailing
from).

There's my $.02.

< Snipped, lots of discussion about weight etc.... >

I am under the general impression ..before Carbon was introduced the rule
was:

i) Epoxy - waves (1 peice strongest)
ii) Aluminium - flat water

Now when Carbon, or a % carbon were introduced, it was NOT to lighten masts
but to improve their FLEXING characteristics. Therefore a Carbon mast will
react faster to gust loads and rapid changes in rig loading (i.e. when
sailing over chop). The larger the % of carbon, the faster the mast will
flex, but there comes a point when the strength of the mast is not aided. I
am guessing now, but for use in waves you would not exceed say 40% carbon ???

my 2 pence worth,

ignore the .sig file, I row too !!
