I bought my 1977 SJ21 two days ago and I'm in the honeymoon phase of a new boat checking out all the blogs and seeing what others have done. I had an S2 8.0 I kept on the Bohemia River on the Chesapeake Bay but didn't use her enough to warrant the slip fees and storage. She had a shoal keel and didn't point worth a damn unless I was sailing under small coast advisories
so I went with the San Juan after reading about her light air capabilities (the admiral didn't like going out in a storm). From what I can see "WindSteeler" is in pretty good shape, I'm a big Pittsburgh Steelers fan and the yellow hull didn't hurt selling her 
can't wait to splash her in the spring!John
