Carol,

I=B9d be more than a little concerned with the loose crane deck plate.  Yes,
there=B9s a lot of stress on the bow cleat but also on the base of the crane,
which is mostly force pushing down and aft at whatever angle the crane is
pointing.  I think there=B9s a chance that you could crane down your mast
without incident, but consider what might happen if the crane base plate
were to let go during the process.  The base of the crane could pop out in
an unpredictable direction which could put the crane operator and the
rigging at something of a risk.  The greatest stress is when the mast is
almost down, and at that point, the crane is pushing almost straight down o=
n
the deck.  Depending on how loose the plate is should dictate weather you
should get a bunch of guys to walk it down manually, or perhaps a
combination of the two=8Bthe more load that the guys could take of the mast a=
s
it comes down, the more stress you take off the bow cleat and the crane.
That said, the safest thing you could do is fix the deck plate before you
use it again.
