Product Overview

Replace rubber mast wedges with pourable Spartite

Spartite replaces mast wedges to completely support the mast and seal the cavity between the mast and the partners. A one-piece custom mast chock is created by pouring two-part 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.

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 supplies needed for installation and allow users to build a simple mold for even the most complex partners.
