Do you really want the fiberglass around the mast to be stronger? Not more flexible? It sounds to me like this bolted-together mast is really just a keel-stepped mast with slots cut in it that a sheet of material goes through in order to keep water out of the boat.
I'm (obviously) not a nautical engineer, but it seems to me that you want the fiberglass right around the mast to be more flexible - like the boot around the keel-stepped mast -- to prevent any horizontal movement of the mast from damaging the "real" deck.
