Lots of boats are great for single handing. Of course unirigs like the H17 and A-class boats are superb, but I used to sail a TheMightyHobie18 and now sail my Tornado nearly all the time by myself. I sail out of Ventura, CA. Did a 45 mile race around Anacapa singlehanded last saturday...3 hrs & 17 min. flat! Could have done better with a crew as the winds were up and I was working to keep her down in the gusts...but it was great fun!
