Friend has a Moody 36 center cockpit. I went out with him once - 40 degrees out side and a nice comfy sail in 15 kts of wind.
His only complaint was that it took 10kts of wind to move the damn thing.
His was the same vintage you are looking at, and had been carved up and redone on the inside pretty extensively - including at one time putting a full sized house refridge in the center of the saloon.
All in all it seemed to handle well for it's design and purpose and was certainly well built.
