I'm happy to hear of your acquisition. I've sailed a mid 80s Cal 24 many times, and I was always impressed by it's stability. The one we took out could cut through swells with authority, and my youngest daughter appreciated that. I also liked the external gas tank storage in the back (vented to the cockpit, not the bilge).
The only quirk we had with the boat was the outboard motor mount put the outboard a fair distance off the stern, and reaching through the stern pulpit was a bit of an art form for starting, shifting, etc. Odds are you'll have a better mount that we did.
