How to get water out of a carbon boom?

[stevemadere]

I have an older Chinook carbon boom with water trapped in the boom arms.

Any ideas on how I can get it out? (I've tried just leaving it out in the sun to heat it up, that doesn't do much).

Wire coat hangar?
Problem is how to reseal it.
Styrofoam of correct diameter stuffed in?

An ounce of water makes a lot of racket without affecting performance. I'd try first to guess at the amount of water in there.

There's got to be a plug somewhere. Remove it, empty the boom, and hope you can achieve a good seal.

Last ditch option is Lee's styrofoam plugs. I stuffed all my booms end to end with styrofoam in the '80s, but haven't had that problem since then. (Ya buy or scrounge a block of styrofoam, sharpen one end of the straight section of an old metal boom arm, twist and shove the section through the foam block to make plugs a few feet long, then shove the plugs through your boom and ... ya hope ... reseal the ends.)

When I get good enough to compete at the world freestyle level, I'll probably worry about a trickle of water in my booms.

Oh, that's right; I don't care about freestyle. Maybe THAT'S why I don't check my booms for an ounce of water in them. SURELY it's the only reason I don't compete at the world freestyle level.
