Jay,

You can free up one of your masthead sheaves for another halyard by
dead-ending the mainsail boom topping lift at the masthead.  You can attach
the topping lift to the same masthead fitting that the backstays use.  At
the aft end of the boom, drill & tap to mount a small cam cleat with
built-in fairlead such as a Ronstan M/N: 70/28.  Please see the 2002 West
Marine Master Catalog on page 1008 in the lower right corner of the page for
a picture of this cam cleat.  Now, you will adjust your boom topping lift
from the end of the boom.  Dynamic Equilibrium has been sailing with this
setup for over a decade & it's been absolutely bulletproof.

The enclosed link is a picture which shows the spinnaker pole topping lift
on Dynamic Equilibrium:

Note that this picture also shows my dead-ended mainsail boom topping lift
described above.

The spinnaker pole topping lift is visible as the line which runs from about
75% of the height of the mast down to the double bridle on the spinnaker
pole.  The topping lift runs thru a Harken M/N: 0082 Single Bullet Block on
a stainless steel eyestrap mounted on the mast.  The eyestrap is attached to
the mast with #10 - 24UNC X 1/2" long stainless steel machine screws, which
are drilled & tapped into the mast.  The screw threads & the back of the
stainless steel eyestrap were coated with epoxy during final assembly to
prevent corrosion & ensure they would never come loose.  I have my spinnaker
pole topping lift led back to the cockpit.

If you want to be able to fly a tri-radial spinnaker such as Dynamic
Equilibrium is using in the above picture; then, you will need to have a
dedicated spinnaker halyard.  You need to have a "spinnaker crane" in order
to get the head of the spinnaker out well in front of the forestay.  The
spinnaker crane on Dynamic Equilibrium is clearly visible in the above
picture if you look closely at the masthead.

Hopefully, this answers your questions.  But, if not; then, try to
reformulate your question as specifically as possible & I'll try to help.
