This can be found on page 100 for specifics.

The field drawing doesn't show anything nice about the 90 degree turn the rope makes in the davit. It's shown as a square tube butted against sheet steel bent into a channel, with some weld. I wouldn't expect it to be sharp, but it's not going to be nicely rounded either. And a smaller rope is much more likely to swing and scrape across the edge than a larger one.
