I assumed the reason for the offset prop shaft on the 30-1 was so you could pull the prop or shaft without the rudder interfering.
I haven't been backing much with my 30-1 this year because I'm at an end slip on a T-shaped dock. I do a U-turn to get in, tie to starboard, and drive straight out (except jogging around the POS houseboat in front of me on which I've scratched my hull once or twice). And y'all are right about choosing a slip with the prevailing wind pushing the boat toward the dock. One time this year the wind was pushing me away from the dock, and a guest of mine fell in trying to hold the boat to the dock. So anyway I haven't been noticing how much prop walk there is on my 30-1. At the start of the year I had half a "normal" double slip. I docked stern-to so my bow pulpit wouldn't be a hazard to people walking by. What I found it easiest to back my 30-1 (with tiller steering) by turning the rudder around backwards. That way the water flowed over the rudder the expected way, without the "sharp edge" upstream, and it felt much more controllable.

I assume that was for one or two reasons. First, to minimize prop walk in forward? And for ease of getting the shaft out without dropping the (rather heavy) rudder. No fun to back the boat. I start way early and drive it backward slowly and then pull it out of gear and drive with the rudder. As was mentioned on an earlier post, it looks funny but is effective. My old slip was down a narrow channel with the slips on one side and a bulkhead on the other - on the bulkhead was a major pedestrian path toward our museum. After many back and forth near mishaps and a lot of tourist entertainment, I switched to the long backward drive down the channel.

I've found that prop walk is pronounced when the shaft is on centerline, but when the shaft is offset, it is offset to minimize prop walk. i.e. If the prop pulls to port, then the shaft is offset to starboard cancelling the effects of the prop walk in reverse. At least, that's how it should be done. Obviously, others here are experiencing things differently, which I find surprising.
