I am a member of the C25 association and I would post your question there. I know there is somewhat of a difference between years/models/types that others know. All I know is that my 1985 Traditional Interior Standard rig/fin keel is short for me and I am 5'10". I have to stoop while in the main cabin, but it does have a pop top, so when we are at the dock it can be raised into position. As Bert says, more info is available on the site. It is a great bunch and you will certainly be welcome.
