I just found your threads and thought I'd post: I have owned S2 27 no. 81 for about two years now. Not much to add to the cabin top traveller discussion, except that mine also has the Lewmar cabin top arrangement. I have changed out the cam cleats, as it was already set up with control lines when I purchased the boat. If there is an owners forum dedicated to the S2 27 somewhere, I'd be interested in joining. Thanks.
Welcome. I have hull #80, build year 1987. I have a question for you. Does your boat have a compression post in the salon? All the literature I've read states that 27s have keel stepped masts, which I am sure the pre-'87 models do. Mine doesn't, however, so I am interested in hearing about your mast configuration.
