I am not sure of your description, but we put a small rocker
on the bottom of the mast to prevent eccentricity in the tube.
(the mast does not sit quite flat on the bottom)
I am not sure I would worry about it, but I am not sure
what you are describing.

I have unstepped the mast on my Coronado 25 and noticed that the mast foot
is flat in the fore and aft direction, but the tabernacle is stepped down
about 1/16" at the middle of the footprint of the foot. Anyone know why
this is? Was there originally a spacer of
some sort between the forward bottom of the foot and the tabernacle? Any
suggestions would be welcome.
