Just got my 76 h30 moved to my back yard. Planning to do a complete refit. Dropped the keel and rudder today. Initial look and inspection of the keel bolts look ok. I had water leaking in thru the hole in the top of the keel for the cable of the center board and migrated to the keel bolts. My keel was designed for the center board but never installed. I'll post more pictures and progress. I'm planning to build a new rudder, repair the keel bolt leaks, paint inside and out, new standing and running rigging, update/redo the interior.
