Spartite Mast Wedge Replacement System

Spartite is a mast wedge replacement system that properly supports the mast and seals the cavity between the mast and the partners. A one-piece custom-fitting mast chock is created by pouring liquid Spartite into the deck opening around the mast and allowing it to harden.

Once solid, Spartite provides even support around the mast section, absorbs shock loads and distributes rig loads evenly. The one-piece ring ensures proper mast placement at all times and virtually eliminates water leaks. It stays attached to the mast when the rig is out of the boat. Kit includes supplies needed to build a simple mold out of even the most complex partners.

Boats in the 36’–40’ length range may require Kit 1 or Kit 2, depending on the amount of compound needed to fill in the gap. Once components are mixed, Spartite sets up within 15 minutes; fully cures in 2-3 days. Kits include everything necessary for installation.

• Kit 1 (51 cu. in.) fits boats in the 20' to 40' size range
• Kit 2 (102 cu. in.) fits boats in the 36' to 60' size range
