My boat is much smaller (30ft) but has a fin keel
and skeg hung rudder
. After many attempts at backing, I had thought that it would be better to begin backing with the rudder in the middle, until I got some flow across it, and then try to steer. But, mine just doesn't work that way. Lately I have started backing with the rudder hard to starboard, to fight the propwalk. As I begin to reverse it will stay rather straight and even turn slightly to starboard. At that time, I am free to steer, but always with the wheel
/ rudder somewhat to starboard from center. If I actually steered to port, it would turn that way quite quickly with the rudder and prop walk combined.
s to your situation, I would save myself the grief, and dock
bow in. Try hanging something soft over the stern to break the pattern of waves slapping while docked. Experiment
with different things till something works. Add a fan for white noise
