Blair, the question is which model do you have,
and what year is it?If it is a full keel, the bolts are embedded in the keel which project into the boat.If it was a centerboard model, most of the centerboard trunk were made of cast iron which rusted and expanded into the centerboard housing and restricted the centerboard from going up or down. The cast Iron centerboard housing had keel bolts also. They were also embedded in the keel housing and projected into the boat. If you are doing a full makeover on the centerboard model, make sure you drop the centerboard ( it is connected underneath the keel like the 23 and 25. Check the archives for recent info) scrape the inside and seal it with good underwater epoxy sealer. This will minimalize any future centerboard problem you may have.The 25's had integral keel housings with the centerboard trunk built-in in the hull so that there are no keel bolts, just the centerboard pin bolts.r.w.landau
