[C38] Spartite VS Mast boot

One of the reasons that I didn't use Spartite was that my mast stood within
1/8" of the starboard side of the partners.  I recently learned from a C38
owner at LeFiell that some mast steps were installed off center of the boat.
I compared my mast step with other C38s this year and finally realized that
my mast step is off center not the partners.  When I replace my mast this
summer, I plan to move the step to centerline which is to port about 1 inch.

Long ago, rope gaskets were used to seal everything on a ship, so in
that sense it is probably OK, but remember that if the rope is not fully
impregnated it will eventually rot, unless it is nylon and I am not sure
what would happen to nylon long term.
	However, the mast partners help transfer the energy from the sail to
the boat hull.  On our boats, the original design was to shim the mast
into the partners with rubber blocks to help absorb shock loads, deal
with flex (from the loading, and temperature affecting the fiberglass
and wood), and transfer the constant energy to the boat's deck.

	With no shims, the loads are being held only by the mast step (about
a
1/2" aluminum plate holds the foot of the mast, and locks it to the mast
step).  I suspect that over time, this would mean some issues to the
step, but you would have to ask Frank Butler or S&S about that.  Also
shock loads may make the mast flex out of column enough to strike the
partners, and could cause fiberglass to crack, or the partners to take
more stress than intended.  Again, the designers could say more about
that.

	Russ, I don't think any yard would step the mast without securing it
to
the partners in some fashion, are you sure there are no shims in your
installation?
