Our family had a 1981 C&C36 from 1980 thru 1990. Essentially the same as the 79 model with different windows. Headroom over 6' - my Dad is 6'3" and could stand upright inside.
The boat is not tender like the 29 or 34 of that area. It is not painfully slow like the 26. It is reasonably stiff and sails well to windward etc... Is not quite as racey as some of the others.
The 9 years we had the boat we were very pleased with it. Yes the windows did leak. If you join the C&C owners email list the process of rebedding or replacing these windows has been covered extensively
I would say is a good boat. Sails well, has interior room and is not piggish
