Rather than use a ss plow $$$ for a mooring, get 3 over-sized Danforths
spread out 120 degrees and leading to a central point with a swivel and a
short chain to the buoy.
I found that the chain becomes a more significant cost, so increase the
anchor size and get by w/ less chain.
With anchors, the mooring can be more easily raised and inspected. At least
in the mud my mooring was set in, there was no detectable wear on the anchor
or chain at that end (the labels were still on the anchors after a dozen
years) . The chain does wear close to the middle (at the swivel), but you
can replace those sections w/ new chain and clevis connecting links.

This is a thick mud/sand bottom, mostly mud. WIth reversing tidal
current (4 knots) I expect the 90 stainless plow to dig in pretty deep
within the first week or two (i'll be keeping a good eye on it during
that time) -

Chuck, it seems to me that with an achoring setup like that, the chain
may very well be held away from the anchor and the monel link might
work.

What do you think - am i being too optimistic (stainless chain and new
anchors are expensive)

Thanks,

Mike.
