Dynafiber: Due to very low failure rate, they extended their mast
warranty from 1 year to 5 years! I've had Dynafiber mast since 1992, my
most used mast, still going strong. Dynafiber booms haven't had enough
track record yet for longevity, but I've bought one last June, which I
only use for high wind bump & jump, and in waves on coast. No problems,
other than a slight elongation of the spring pin holes. They are
correcting this for '96 with a different adjustment system.
Gulftech: I have a carbon gulftech boom, that I've had since '93. I
used it originally on a 7.5 race sail, but now I only use it with my
6.9 and 6.3 race sails, with an occasional jump. It's still going
strong.
Powerex: Prepreg carbon epoxy construction masts. My wave masts are
either the Powerex Carbon Wave, or the Dynafiber Tsunami Wave.
Nolimitz uses prepreg carbon, but I have no experience with them.
Generally, carbon prepreg construction in masts is going to be much
more reliable. Dynafiber uses a braiding machine (developed by K2 Ski)
to braid the carbon fiber onto the mandrel. Also a very durable
construction. Fiberspar uses the cheapest method of laying up carbon
fiber (wetting the unidirectional carbon cloth by hand).
I stopped using aluminum booms, because the salt water corrodes al
quickly, which leads to premature failure. But then again, al booms
are cheap. Carbon booms are expensive ($250 - $300).
