Spring lines plus a wheel at the corner of the dock you are gonna pivot on should work fine. I've seen people actually just manually maneuver boats out of difficult slips from the dock with lines, yank em around and get em pointed the right way from the end of the finger peir, then step on and motor off. Nothing says you have to do it the hard way.
I was out with a friend in his cape dory 28 the other day and we were practicing spinning the boat with propwalk, power bursts against rudders, etc. It was pretty cool, you can actually just more or less sit there and spin if you need to and are in practice, but I finally mentioned that I wasn't a power boater and would like to do some sailing. hahah.
capt ken has it right, make some buoys and go out and spend a whole afternoon practicing someplace wide open where a mistake won't mean anything.
