Did the bolts thread or stick into the
aluminum disks? If so did you have any trouble getting the holes aligned when
stepping?
The previous owner of my boat did a
similar thing with oak but eventually it abraded where the bolts/pins went into
it.

Life span of carbon masts?
Chris,
\
Provided you can avoid lightning strike (which causes the
carbon fiber to delaminate and very effectively destroys the mast), and
provided you can avoid chafe (anchor rodes, dock lines, etc)
the mast stand a good chance to last longer than you or me.
\
There may be one inch thickness at strong points, but, even at
deck level, I found no more than .25 inches and as little as
.125 inches, when I examined the stump after the mainmast had let go at
deck level. Watch that chafing !
\
Themast had let go not because one of the above
causes, but because the heel of the mast, stepped on the keelson in
an alumimum collar, was secured to the collar with 5/8 nch set
bolts, (to prevent rotation of the mast). When I accidentally
beached her, in 6 ft surf, the wild action on the bow was such that those
two set bolts chewed the dailight out of the mast walls, and a few weeks
later, the mast, having no or little support left on the heel,
broke at deck level.
As a result I pulled the still standing mizzen mast
and “plugged” the inside of the heel with two solid 1"
aluminum discs. That mast has never given any trouble in over 24 years.

Hi all;
\
My first post to the list, I am boat shopping, and wanted to
learn a bit more about the Freedom Boats.
\
I have a simple question. What is the life expectancy of
carbon fiber masts? No specifically the Freedom masts, but in general?
