[Rhodes22-list] Swinging at anchor?

[Hank]

You also need to ensure that the chain between the float and the anchor is
inspected.  I used to have an Islander 36 and kept it on a mooring at the
Naval Academy.  I got a call one day that my boat was missing.  It turned
out that the chain had broken near the anchor and the marina had not
inspected it sufficiently.  Fortunately, the weather was pretty calm and it
had gently floated across the river and had very little damage. The marina
was able to go over and bring it back that same morning.
