When leaving my slip, I have to make a quick 90 degree turn or run into the next downstream pier. When doing that when the current is running strong (and possibly with wind too) if you don't make that turn very quickly and with decent headway, you will end up against the boats at the next pier. At times you have to actually "crab" your boat at an angle into the current till you clear the channel where the piers are lined up perpendicular to the current. If you have a single engine and no thrusters, you don't always get to come and go when you want to.

When conditions are not bad, I practice w/o thrusters, but I don't have a lot of prop walk anyway. Using forward and reverse thrusts I can get the boat to turn when the current is relatively mild.
I was in a river marina and know what you are saying about currents and crabbing.
The last two posts tell me you should not be stern in but bow in.
You need headway to turn, water flow over rudder to steer. The current neutralizes some or all of that flow. Try bow in and back out. You should have more control bow to current.
