Al,
If you want to try my slip for size, let me know. Or just go to a marina and try a few and measure once in.
If you get into AYC and you go for D Dock, wind is normally at stern, which makes docking easier.
C Dock is a little trickier. A and B don't have as much wind, but wind is normally to your side, which can also be tricky.
If slip has 4 poles, then it's easy because as you back in normally your between the poles sooner and your boat neighbors become less of a issue then. As I stated in other post, your boat has a narrower than boat swim platform, which makes it easier to get swim platform into tight slip, but then you need to line up rest of boat which is a quick walk over. Can have passenger hold fender on those rounded corners to help.
