Spartite is the modern answer to the ancient problem of mast support and sealing in the partners. Spartite is a pre-measured two-part polymer poured into the cavity between the mast and the partners while the mast is in the boat. Each kit comes with complete instructions and materials for the yard or yacht owner to build a simple mold out of even the most complex partners or mast collar. Spartite makes a one-piece, perfect fitting mast chock that replaces archaic wedges.
