I love the fact that she put on the top of her list, helm station she can get too without having to climb over the lazeratte to get to. ...
You raise an interesting point that is at the origin of the modern concept of the two wheels setup: If you have a small wheel you would lose the best and more comfortable position to sail a heeled boat, I mean sitting on a side.
with a small wheel you cannot reach the wheel siting there, or you have just to bend forward making the position uncomfortable. With a big wheel it is more difficult to go forward but you can comfortably steer the boat sitting on the side with the foot on the pedestal.
The two wheel setup have just solved that. On an older boat you have too chose between a better sailing seating position or an easier passage on the cockpit
