What is this?

I found this on a Commander and I don't know what it's for.

Thanks for posting this. I got the same in my box-o-stuff and I have no clue. I thought it might be some kid of slip-over-the-boom vang holder. Inquiring minds want to know!

You got it! I felt a little ripped-off after digging through all the stuff that came with 113 and there was none to be found. Frame and matt worthy...

it's the claw for a roller boom, slips over the rolled sail for use as a vang I believe.
Got one with the Triton, but not the Ariel.
Odd, because the Triton had been converted to single line reefing, and the Ariel still has roller boom.

Ken.
