We joined up to HSB last spring, my wife and me went through their initial basic keep boat class. The instructor was OK, I got through the class but wife had a tough time. The instructor was not very patient with her and once the "fun" of learning to sail was gone, so was she. As far as the club, they have a nice staff and very nice boats, once you figure out their system of reserving boats it seems to work well. Also, sailing in San Diego Bay is awesome!
I would be glad to answer specific questions if you have any.
