Good question. Only time I've retired them is after they actually break. Most of the time that's happened when I get tossed in the ocean and am not too far from shore. Sorry that I can't answer the question.
Wow, sounds exciting!

Most of my broken masts have been in waves, my suggestion would be a close visual, for small cracks or camber groves & ect. unless you get alot of water time it takes a long time to fatigue one to failure.
Good info, thanks

I agree, Chuck. I keep mine out of the sun while storing and they last for years. I have a couple that are at least 15 years old. I'll continue using them.
I've found the following works:
test that sort of works:
borrow it or lend it to a good friend to use, either way a very good chance it break under just about any conditions,
test that always works:
sail it offshore a little more than 7 miles, it will break for sure.
Sorry great question that I wish I knew the answer too....
