Greg's thread made me think about my old Chris-craft Cavalier and how it was set up. It had solid shaft propulsion. And looking from the back, it had the rudder just left of the prop. I wonder why it was set that way instead of being directly behind the propeller instead of offset the way it was. Also I wonder why only one prop instead of two. It was a bugger to back out of a slip .

When underway everything was fine and would steer well regardless of speed or direction.
Any ideas?
