Vang connection on F30

The ring at the base of my mast that connects the mast end of the boom vang (the center ring) has been broken off. The previous owner has crimped a wire between two of the other rings to the vang which looks dubious at best. I was wondering if anyone else had an idea for attaching the boom vang to the mast. I have seen a heavy duty metal cuff that surrounds the mast that was probably fabricated for the boat, but if anyone knows if this is a item that can be purchased I would love to know. I would be open to any other good ideas. Also are these rings a known weak point?
Thanks

I had the band you are describing made by Garhauer Marine when I installed rigid vangs on my Express 39. I would recommend Garhauer.

Garhauher Marine sells this for the Freedoms. I bought one for my F38 about 4 years ago, so don’t recall the details, but they’ll size it for your mast. They need the diameter of your mast at the bottom and about 9 inches off the deck, if I recall correctly. Just give their tech support a call (909-985-9993). I also bought the rigid vang to hold up the boom. Excellent upgrades for the boat…

Thank you. I have contacted Garhauer marine.
