Do you really think a swivel is necessary ? Unless you are anchored for a
long time in a tidal current I wonder if it helps or hurts.

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

I have found it necessary with an all chain rode and a windlass. This
is my second boat with that combination and have ended up adding a
swivel both times to avoid chain hockling and to ensure that the
anchor comes up straight over the pulpit roller and in the right
orientation.
