A lot of folks suggest removing this mast base, rebedding and reinstalling the lag screws.
This is for a Catalina 30, mk1 from 1982.
As with many old boats, moisture at the mast base is sometimes an issue.
A surveyor one year ago detected elevated moisture in this area. After speaking with the factory, I drilled small inspection holes near the mast base from in the cabin below. No water drips, and the shavings that came from the holes were light colored and dry. No deck depressions in the area, compression post block (wood from 1982) in bilge still solid.
All of that said, I really do NOT want to mess with this.
The "challenged" VHF antenna cable stub is another story.
Lastly, I saw on YouTube folks pulling a new forestay through an assembled string of furling foils (removed from boat, drum removed from furling foil but foils still attached with connector pieces). I have a Hood SeaFurl 810LD. Is this possible? Everything on YouTube looks easy
