bravo eyelet posts

This is a quick question for Bravo experts.
I snapped an eyelet post. Do they just twist off with a wrench? I tried, but didn't want to apply to much pressure and strip/break anything.
Thanks.

I've never removed one but I believe they're riveted so will require drilling to remove?????

Thanks, Matt.
That's what it looks like-a rivet.
A search of replacement parts shows only the plastic eyelet posts (the sleeve around the rivet, but not the rivet itself). So drilling out the old one gets me only halfway there. I'm towing the Bravo from Pa to Florida for vacation tomorrow, so I'm hoping that the Daytona Hobie Dealer can fix it right away.
