I had the same feeling when I first got our R27 Classic. We came from a stern drive instead of a sailboat but still very different. After 7 years with our tug I can’t imagine anything easier to handle. With the thrusters even easier than our 19ft cuddy. You will get used to it and love it. I know people that have gone from the inboard R25 to the outboard R27 and had the same comments. You’ll learn with time and wonder why you had any problem before.
My only additional advice beyond what is said above and in the linked thread is to think about “momentum” and “thrust”. The boat does not steer with the small rudder and keel without thrust. Once you have momentum in a certain direction (including radially around a centerline point near the helm, about 35% from the bow) the boat will continue in the same direction and rotation unless you use thrust (the steering wheel is nearly useless without thrust and always is useless in reverse). When docking, line up your approach, stop all motion, read the wind and current, and then give enough thrust and steering wheel to create momentum in the direction and rotation you want to go. The thrusters can then be used to make small adjustments as your momentum takes you into the dock.
