We bought a 1979 C&C24 in May last year. Good little boat
Ours has a head under the v-berth, but ours is a different layout to a lot of the 24's out there which have it at the rear near the companionway with the seating that goes across the entrance to v-berth.
We also have a traveler and all lines lead back to the cockpit so we have a complete set of sail controls in easy reach, lacking a furler on for foresail but no biggie. She's a fun boat to sail, pretty stable and pretty quick (original sails and I can still get clipping along at 7knots). The standing rigging seems to be somewhat oversized and overall the boat feels really solidly built, she feels like she'd put up with a lot of abuse from the weather, the sea and the owner lol.
Lots of room inside (for a 24 footer) as she's quite beamy, certainly OK for a couple for up to maybe a week of cruising as long as you aren't 6ft+.
It's a lot more boat than the Catalina 22, we looked at things from Cal20's up to a couple of 27 footers and the C&C24 ticked the boxes,not too big for a first boat, but not so small that we'd outgrow it in a season.
If you haven't been to see it yet, I'd definitely consider going to take a look, there's no real substitute for your own feelings about it.
