Jib won't do much
I own a Freedom 30 and love it, but I doubt it would move under jib alone. The power in the Freedom rig comes from a large, fully battened main. The jib is small, self-tacking and basicially vestigal (although a handful of owners have retrofitted larger jibs). You can easily sail with main only, and tacking and jibing is little more than simply turning the wheel a quarter turn. There are also some twin-masted Freedoms, but I've never sailed one and can offer no thoughts on them. Because of the lack of a big headsail, most Freedoms aren't great in light air, and they're said not to point as well as other boats. I have new sails and think she points almost as well as a traditional rig. There's a fairly active Freedom discussion group on Yahoo.
