If you go the Spartite route, make absolutely certain the inside of the partners deck “ring” on the boat is 100% smooth with no ridges. I put in Spartite 20+ years ago and did not notice a slight ridge [< 1/8”] in the inside circumference [wider at the bottom and narrower at the top] which when pulling the mast the first time would not release. The boat was actually lifted 6”+ out of the water before the crane operator stopped. Had to unbolt the AL deck ring to pull the mast, then pound the Spartite / deck ring off the mast, then grind down the ridge. Was flawless for subsequent pulling of the mast. And make certain to reapply your lubricant of choice [Vaseline / KY, whatever] before stepping the mast. The Spartite needs to be covered to protect it from UV degradation.

Are there other ways to shim a mast for a DIYer? Chuck S Your contributions help pay the fees associated with this list and help to keep it active.
