So, has Glenn succeeded in destroying any of these to see about their
strength relative to the chain itself? I read of many boats surviving
hurricanes whose chains are so distorted they'll no longer fit in the gypsy,
so I expect these swivels would cause serious deformation, or even failure,
of the chain before breaking, themselves. It also seems that putting a
serious load on, and then inducing twist, would be needed to do a
"true-life" test...

=================================

I guess we'll have to wait and here from Glenn on the testing. The
European stainless steel unit that someone recommended cost around
$300 so it's not likely we'll see much "testing to destruction" on
that one. I'd have some concerns about mixing a stainless swivel with
galvanized chain and anchor in any case.

If the chain distorts but you and the boat survive the hurricane,
that's a small price to pay in my opinion. With 3/8 HT chain the
difference between SWL (no permanent distortion), and ultimate
breaking strength is about 10,000 lbs so it is easy to see how that
could happen.
