Whisper has a tiller. The Challenger that Tristan Jones sailed had one too. I believe that it was also a Palmer Johnson boat. Advantages of a tiller include: better sailing feel, more fun, ability to steer while under dodger in bad weather, more room in cockpit, no steering gear to break or need repair, ease in rigging self steering (as Jones did in Indian Ocean) or tiller autopilot. Disadvantages: ?
Are there any other Challengers with tillers?
