Still trying to stop camber inducers eating my carbon mast.
I put some epoxy (the 5minute stuff) on the worn part and let it
cure in a warm room. Looked real good. Lasted one session.
The cambers wore throug in exactly the same spots.
Checked with shop-staff (experts on my sail). Sail is rigged
perfectly and rotates easily. Cambers look ok.
Checked with someone who uses same sail on different brand
carbon mast. Some sand in Cambers but no wear on mast.
So it must be my mast that is too 'soft'. It's a Sailworks
65% carbon racemast.
I wrapped some tape around the wearmarks now, to see how that works.
Anybody got any better ideas?

Two years ago I had the exact same problem, my NP MKII was eating my
NP carbon 60 mast. I laminated a verry thin layer of glass on those
places. This worked fine, it stopped the problem. When my mast finaly
broke it was at an other place, the place where you can part the two
pieces.

I then bought a new mast, again a NP C60 and a NP MKIV sail(with the
roller cam). Now the problem has dissapeared. I don't know if the
mast has gotten better, or the rollercams are a lot better.

Succes

Hi,

I just started reading your post, so I'm not sure if this was already suggested.
My carbon mast was starting to show cosmetic wear from my camber. This resulted in
me noticing other people's masts to see if they have the same problems. One guy
had cut a diet seven up can (the top and bottom), and wrapped the area where his cambers rest on the mast with the leftover metal cylinder. Then taped it in place.
He said a lot of his friends who race (I want to add credibility to the solution :) ) do that, and it seems to work great.

Mind you, I'm a fresh water guy, so I'm not sure how this solution will hold up to
salt. Try that, it might work. As for rust, the diet seven up can is made of
aluminum, so don't worry about that part.

Good luck...Amro

I have done the same with a Gaasta WC carbon mast. I got some strips
of fine glass cloth, wetted the area with epoxy and laid the glass
(only one layer thick). Don't try to put any epoxy on top of the
glass. Just make sure it is wetted out by squeezing the surplus epoxy
around. It will soak through. This kept it smooth and doesn't seem to
affect the rotation too much.

Hej, bill!

I've also got those problems, but I use this very strong silver tape, and
change it now ant then. And it works quite ok with my sail....
(and I surf in salt water and sand)

...On the same subject: I have found that when pushing the mast up the
sleeve, downhauling and outhauling, t***, the
(roller)-camber-inducers may not end up `right angles to the mast':
they are still pointing up. So I over-outhaul now, and straighten the
camber inducers, and then let off the outhaul. This made a big
difference to
1) ease of flopping over and 2) reducing mast-scrathing.

Cheers.
