If you back *directly* into the wind using low RPMs prop walk should not be much of an issue and you will come in at an angle to the dock if the wind is as shown on your graph. That will keep the wind from blowing your bow. Since you are backing directly into the wind, you can go nice and slow. Once you get near the dock, your
line handler can jump off the back and wrap a
cleat with the stern
line. Then forward gear at low RPM will pull the bow into the dock despite the wind.
I do this whole operation at 1000 - 1200 RPM. As long as you keep the RPM really low, things will happen really slowly. Once the stern is to the wind, the boat will just sit there happily for a long time. No need to rush anything.
