Mast Partner Support/Sealer Kits
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 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.
Note: Size Large is also needed for all unstayed rigs under 40 feet, such as a Freedom or Nonsuch, or if you have an unusually large gap (over 1") between the mast and collar.
