not really, except for those too weak to haul up an anchor and who feel they
REQUIRE an electric windlass.

btw, depth of water is NOT the reason to carry 300# of chain (chain is
mostly
useful in coral and/or rocky bottoms, and even then you really, really,
really
want not much more chain than might be needed to stay off the bottom).
people
carry 300# of chain because chain goes through an electric windlass easier
than
a chain/rope rode does. In other words, it is useful if the boat owner is
too
weak and decrepit to haul up by hand 35# of anchor and 20# of chain, or
manual
windlass 45# of anchor and 40# of chain.

I suspect opinions will differ on this
