[Rhodes22-list] anchoring - snubbers

[Robert Skinner]

The chain does act to some extent as a shock
absorber, as it is being lifted off the bottom.
A properly sized nylon line also provides some
cushioning effect as it stretches.  For a storm,
however, I would use rubber snubbers on a bridle
as the final piece.

In a hurricane hole, anchoring stern to the
shore is an old practice, as the bow handles big
waves better.  Double anchors forward, of course,
with slack for the tide/surge.

Of course, Maine sees a daily tide of 8 to 20
feet depending on location, so surge does not
seem so pronounced.
