Spartite Mast Partner Support/Sealer Kits

Mast Partner Support/Sealer Kit

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.

The Spartite ring shrinks less than one thousandths of an inch and, when installed properly, will radically reduce or eliminate leaking at the partners. Spartite ensures secure and correct mast position in the partners all season and makes correct placement of the mast in the partners automatic whenever the mast is restepped. This is an exceptional feature for racers who trailer to regattas, sailors who remove their spars annually, and boats with unique rig placements. Racers, who like to move their mast fore and aft to adjust to conditions, can pour Spartite to fix the athwart ship position of the mast and allow space fore and aft for quick, easy adjustment by the addition or removal of spacers. Under sail, the one-piece structure of Spartite elimates the problem of wedges falling out or moving.

#1 - Small

Kit Size

 Small

Boat Size

 Under 40 Ft. LOA*

Kit Coverage

 51 cubic inches (836 cubic cm)

* 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.

To estimate the quantity of Spartite® needed, measure the square inch, or square centimeter, area of the mast section and subtract that number from the square inch, or square centimeter, area of the partner opening. Multiply this number by the desired depth, which must be at least 2" (5cm), then add 1/4" (7mm). If you purchase too little, a further amount can always be mixed and added later.
