Spartite

Spartite is the modern answer to the ancient problem of mast support and sealing at 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 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.
