NO Genoas Usually
The general recommendation for the Hunter 26/260 is NOT to use a genoa sail since the jib sheets would have to be adjusted and equipment added. While I'm sure some have done this, most who want extra power in light winds opt for a crusing spinnaker which is easy to fly - especially if you have a furling jib. I'm sure someone had done this and can tell you how it works. The archives on this site probably have had some discussion on this issue. Good Luck.
