When we bought the boat there were only a few wedges in place, not enough

there another system that would work? Say just filling the partner with
silicon, would this allow to much flexing? How firm is the SparTite after
it sets?, does it allow some movement or does it harden as a solid rubber?

One of the guys in my YC seals the mast opening with a piece of line
jammed into place (ater adjusting the stays to give him proper rake),
then coats it with silicone. Since we have to drop the mast every year
for haulout, it seems to work well for him
