Best way to waterproof keel stepped mast
Spartite is not used to water proof a keel stepped mast but is used to replace wood wedges between the mast and partner at the coach top. A neoprene mast boot should be used once the spartite cast has been formed and cured to cover the area where you have installed the spartite. To minimize water entering the boat and bilge, I suggest that you fill the sail track for the sail slugs with silicon just above the mast boot and hose clamp. This does not eliminate water entering the boat as rainwater will find it''s way into the bilge by way of openings in the mast such as sheaves, halyard exit plates and holes used for antennas and wires. I have used my original cast of spartite for 6 years, each year pulling the mast for winter storage, no problems, a great product.
