Why not cut off the bad area and the comptip, paint it, put a pulley on top and use it/sell it as a floagpole? Have you piced flagpoles lately? A 20 footer is over $200.
I like the trophy idea too. Or maybe crossbars for an outrigger canoe.?
Sorry about your woes. I have a Nacra 5.5 Uni mast in my basement broken exactly in half with no other dents or scratches. Each piece is 15 feet. I keep thinking I will use these for two A-Class boat crossbars (7.5 feet each)....
