I'll chime in - as much rudder and CB as you can use. Full is preferable.
But the odd part, well another one of them, is that with no power (engine at idle or in neutral), it steers like a keel boat, sort of. With power, it steers like a power boat.
When going slowish with no power, you can steer the stern around in the normal (for a keel boat) way, but when you hit reverse to slow forward motion, the prop will pull you in the opposite direction the rudders are trying to steer you.
So when moving forward and pulling in at a wall, you would come in at an angle, get very close (almost touching the fenders), and put it in reverse to slow and stop. To swing the stern into the wall on a keel boat, you would steer opposite the wall to pull the stern in while moving forward, with the engine in reverse to slow and stop you. With the Mac, you do the same thing until the prop, which is in reverse but directing thrust in exactly the wrong direction, takes over, at which point you cut the wheel towards the wall so the prop can pull you in. A little burst usually helps here. But the directed thrust of the prop when in reverse while the boat is moving forward takes some getting used to.
Same thing happens when backing into some place, putting the engine in forward, and now the stern is doing exactly the opposite of what it was doing a few seconds ago.
Once you master the two-stage slowing and stopping bit, you can grease it in like a pro, taking advantage of the keel and directed thrust for sharp turns, and the rudders for slow, no power turns. Just gotta be quick with the wheel and throttle.
Now crosswinds, that's not fun no matter what.
