Any sailors with 490 rdm masts?

Hi group,

The summer doldrums are creeping up on us here in NC, and I'm
reluctantly turning my attention to the big gear.  Planning to upgrade
both my 490 mast and 9.0 sail.  I'm intrigued by the prospect of using
a large rdm, such as the Gultech 100% carbon 490. It will be partnered
with a Windwing Hammer in 2-cam mode to cope with the gusts on Lake
Jordan.  (As an aside,  I'm told that some photos from Jordan are in
the latest NewJ -- Raleigh is the latest windsurfing destination...not!
:-))

I realize there have been concerns in the past about the stiffness/bend
characteristics of big rdm's, and wonder if these concerns have been
confirmed or dismissed by actual experience. Can any rec.dotters out
there provide some testimonials regarding their experiences with large
rdm's, especially (but not exclusively) the Gulftech?

Thanks!

Charles L.

Not quite as big as the rig you're talking about, but I have been
sailing my Windwing 7.0 Quantum with a Nolimitz 460rdm and even at
200lbs, it feels really good.  Lots of range and quite tunable.

I'm 220 and have sailed a 7.8 Ezzy 2 cam Infinity on a 490 RDM for a
few years.
Its alright for what I use it for - bombproof, durable and pretty good.

Cams work fine after initial adjustment.
Not as snappy and crip as a regular mast, but good enough.  Feels more
like a 75% carbon standard mast than a 100% carbon standard mast.

460 and below, and I love the RDM's in the wave sails.
For 9.0, I think I would prefer a high modulus or reflex SDM (compared
to my Ezzy Powerex RDM mast).
But if you are not sailing the 9.0 OP'd and gusty (and/or you are not
that heavy), it should be fine for recreational early planing fun.

YMMV, since you are looking at Gulftech.
Their RDM's may be more responsive - I do not know.
Responsiveness and reflex is the only issue for me.  In all other
regards, SDM are superior.  One thing that helps is to use RDM on a
sail that was designed for RDM.

I bought a 490 skinny Gulftech and cut it down to about 475 and my
Pryde's rig up SWEET on it. ;-)

Hello Charles,
(Not sure if my first attempt to send this succeeded)
I have been using EZZY skinny 490s for more than two years and I notice
no difference in my sail performance when compared to either a
Fiberspar 490 or 460.  I'm rigging my 7.5, 8.5, and 9.5 Infinities on
the 490s
When I started using the 490/9.5 combo I met a guy in Hatterasnamed
Robby Naish who checked out my set- up and said it he felt the mast was
very stiff.  (Sorry about name dropping but it is a true story, really)
I don't know anything about the Gulftech but I hope you get an
opportunity to check out the EZZY before you buy anything.  I'm
guessing that the cams on the Windwing are skinny compatible?  Check it
out first.

Hey Charles,
I forgot to mention boom and extension compatibilities;
Make certain that the skinny boom shim will fit in your boom head and
note how tight it is- this may make height adjustments on the water
(while standing up) more difficult.  The NoLimitz style boom shim fits
all boom heads that I've seen but the older Powerex does not fit in the
Chinook Triple clamp head.
Chinook and Streamlined manufacture extensions long enough for a 490 to
fit in a 9to 9.5 sail.
