I personally have never broken an N20 mast, but I figure it would only be a matter of time with my "extrodinary" skills at breaking stuff.

I'm just looking at the possible "green" side of aluminum vs. carbon.

My trophy consisting of a small section of Ryan's N6.0 aluminum mast does look rather nice on my bookshelf. I guess you could cut a broken carbon mast into sections and make trophies out of them for future regattas....

And if N20 carbon masts can be successfully repaired, why aren't they? Did the insurance company require you to toss out the broken mast?
