I had an '81 on Lake Superior. It was a great boat, especially in light air. With a reefed main and a #4 up, I could sail in 35knts no problem. The only problem with the boat, other than the normal age stuff, is the holding tank
I talked to one of the original C&C designers and he mentioned that the tank doesn't suck enough air during a pump
out. This can cause the tank to crack at the outlet fitting. I added a second 1/2" air intake and the problem was solved.
I would hightly recommend this boat.
