Spartite Mast Chocks

 

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.

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".  If you purchase too little, a further amount can always be mixed and added later.
