I believe that shrouds are sized to about 3x the expected static load
per wire at 30 degrees heel and headstays around 15 times. This seems
to put the two types of stay into noticeably different categories when
doing stress calcs. I'm with you on newsgroup expectations, of
course. Though, as I mentioned before, there is a very complete
discussion of how to do these calcs including a worked example in
Larsson & Eliasson's book.
