I just purchased a new 2-piece mast (a $199 Serfiac Carbon 30 mast from a mail order company).
I also have a 92 (or 91) NP World Cup 6.0 sail which has 4 cambers.
My problem is that the cambers seems to scratch the mast when they rotate leaving a clear cut
on the mast (pretty similar to a cut you would get by using a knife).
With my previous mast (a BIC cheap stock expoxy mast) I didn't have any problem.

Now, I'm wondering if the coating of the mast is too weak/thin/cheap.
Have you heard about this kind of problem?
Is there a solution to it? (apply extra coating, use scotch tape, use a piece of mylar,
use a file to smoothen the edges of the cambers, etc...)

Thanks for your help.

There may be a reasonable way out: buy some of the new NPryde Roller Cams
which are standard in the Mk IV. Just replace one or two of your  Cams to
check out wether it works. You should be getting both no scratches and much
smoother rotation.

Not feasible with a 4 camber race sail, I realize, but it worked for her.

You might try upgrading to newer cambers, or perhaps gluing some soft one
inch hollow cloth "tape" to the inside of the cambers. The "tape" I'm
refering to is climbing "tape", made of synthetic cloth, similiar to what
many uphauls use (i.e. 4 knots). You can get it at REI or a climbing store
if you can't find it at the local West Marine or similiar boating store.

My old Waddells, and some old Norths, use cloth like this against the mast.
The newer Waddells have a small all-plastic "T" cambers, but I don't know
if they scratch the mast of not.

Good luck,

Jaime
