Tiller vs. Wheel
I have to strongly agree with Jack on this that a tiller is very preferable on a resonably modern boat that is less than 12 meters and that it is only US prejudice for wheels that make them so common over here. With a tiller it is easy to place the controls where they fall easily to hand while on the tiller and also placing instuments on the bulkhead or on a pod over the companionway, allows you to see both the jib slot and your instruments. Placing instruments on the wheel pod makes them only visible to the helmsman when motoring.
A tiller also has the advantage of allowing you to move around the cockpit using the tiller extension so that you can make adjustments and still keep a hand on the helm.
