Can you help me identify the purpose of these? (swim platform/davit - 44DA)

I have a St. Croix model SC650 (I think) davit system on my 44DA. It works great. Dinghy needs some work, so we took it off...

But my questions is...what are these for?

I don't think they are a part of the St. Croix system. Are they a part of another davit system that could have been on the boat previously?

Brackets for the original Hurley davit. Have them on mine.
